Reasons to Choose Submersible Winding Wire

You will find that makers of electrical goods prefer to use the copper wire because of safety reasons. This is the reason why copper wiring is most extensively used today, even when there are others like fiber optic cables. Copper wires are chosen because of their ductile strength, their longevity, malleability and high electrical conductivity. The copper strands are thinner compared to human hair strands. This explains why they can be conveniently bent and twisted depending on your needs. So, copper wires are best suited for those places where movement is highly constricted. When you choose copper wires, you will never have to worry about these getting broken or damaged. Besides, installing such wires is easy and hassle-free. The submersible winding wire variety is used for the submersible motor pumps.


Why copper wires make submersible winding wire:

The copper wires which are used underwater have high thickness of nearly 0.4mm-3 mm. These wires have also show excellent results in shock tests which have been conducted in various environmental conditions. This is why the copper wires are found to be the best choice for submersible operations. Moreover, wires are expected to be designed in such a manner that they are able to resist sudden voltage bursts without causing any interruptions. For this reason, the submersible winding wire is chosen.

Such winding wires find a lot of use in different types of electrical appliances such as transformers, inductors, loudspeakers, headphones, generators etc. The main idea is to pass electric current through this wire and ensuring that the current so passed is not wasted in transit. It main usage is for electrical appliances which are submerged in water.

How to choose makers of submersible winding wire:

When you are looking for copper wiring products like the submersible winding wire or copper foil, you should find a reliable provider online. The submersible winding wires are now used in different critical industries and for time-sensitive tasks like shipping and travel. Copper products such as this wire and copper foils are used for making submersible motors which are both heat resistant and water resistant. They are also resistant to oil and heat, high voltage, acids and alkalis and even salt. So, for industries whose applications are submerged under the water, these products are very useful to get optimal performance.

When you have shortlisted some manufacturers, you should look at one which offer quality products that will be resistant to both high temperatures and mechanical wear and tear. The company should be able to provide you with submersible winding wire according to your specifications. Moreover, the company you choose should have customer-friendly return policies so that you can get the wires replaced if there is any defect or damage. The wires should ideally be made from poly propylene and polyester so that they can take in maximum pressure and also withstand extreme temperatures under the water. The copper wiring which is used by the manufacturer for producing the submersible winding wire should be of very high quality to yield optimal results.


Why Tin Coated Copper Wire Is Better Than Bare Copper Wire

The golden red metal, copper, has many advantages that make it a wonder metal for several applications, the chief among which is electrical. This metal has been used by humans for thousands of years now. In fact, copper became so widespread in terms of use that an entire age has been dedicated to it, and it sits comfortably between the Neolithic Age and Bronze Age.

Change is in the air

Humans discovered that if another metal was mixed with copper, it changes its properties for the better. That led to several alloys being discovered. Bronze, a copper alloy, is a mix of copper and tin and brass is a mix of copper and zinc.


These alloys were much stronger than copper alone. Also, they could be more easily cast. This opened a whole new world where copper could be played around with to make it more usable for different applications. Copper is used in various forms such as bare cables, wires, bars, Braided Flexible Connectors, and more in various fields.

Copper turns green when it is exposed to the air. A famous example of oxidized copper is the Statue of Liberty. The colour change may not have been an issue, but the oxidation is a semi-conductor, which on top of an excellent conductor like copper is not good news.

To control the issue of oxidation in copper, a method was found where covering bare copper strands with tin helped immensely. Apart from saving it from oxidation, it also added durability to it along with longevity.

Covering copper with tin

One way of preventing oxidation is to cover copper with something, usually plastic, to eliminate contact with air since no air means no oxidation. However, the minute the cover goes off, oxidation will occur. The answer to this is soldering the copper in. Once that is done, air does not get near the base copper strand, leaving it resistant to oxidation.

There are two methods that can be followed to cover copper wires in tin. One way to do that is by dipping the strands in hot molten metal so that they are covered completely. This is called the ‘Hot Dipping’ method. The other method is electroplating. An electric charge is passed through the strand which allows tin to stick to it and cover it completely.

The biggest advantage of tinning is that it adds to the shelf life of copper. Copper’s natural strengths are boosted several times over, and it is believed that tinning amplifies copper’s longevity by ten times.Connectivity of copper is also enhanced since tin is a primary soldering component. The tinning process makes copper almost impervious to high humidity conditions, wet environs, and high temperatures.

Tinned copper is used extensively in many applications, even high-risk ones such as in the marine electrical arena. It can be safely said that tin coated copper wire is much better that bare copper wire.

The Convenience and Safety of PVC Coated Wire is Well Established

Today, polyvinyl chloride or PVC coated wire is the most common type of wire that is used for electrical applications all over the world. There are many reasons why these wires have become so popular and the most important reason is that they are highly effective as a non-conductor of electricity and are really easy to use. In terms of durability too these wires are quite long lasting as they are said to remain strong and robust even after four decades. Many of the wires with PVC insulation nowadays don’t burn even if exposed to fire. With that kind of strength it is but natural that such wires are preferred over all other types of electric wires and cables.


A safe and robust material for insulation

As an insulation material for electric wires and cables, PVC is the safest that is presently available. It is not just non-toxic but has very little impact on the environment compared to any of the other materials available for insulation of electric wires. Considering its much lower weight polyvinyl chloride is mechanically quite strong and tough in addition to its capacity to resist abrasion. Besides, the material has been tested over a long period, across different conditions, absorbing all the improvements that came along. Today, it easily meets all the guidelines with regard to health and safety standards worldwide.

The dielectric strength or the capacity to resist volume, in PVC coated wire is the metric for measuring its properties that enable electrical insulation. The electrical resistance per unit volume of the testing sample indicates the capacity to resist volume. On the other hand, a specific unit of voltage is applied on the testing sample for a pre-determined length of time to obtain the dielectric strength of the material. Such strength is reflected in the quantum of voltage that the testing sample has been able to withstand without any damage to its structure. In both the measurements, it is the higher value that proves the strength of the material for electrical insulation.

Increasing applications of PVC insulation

Prior to arrival of the PVC coated wire, soon after the World War II, the insulation on wires used to be of rubber, which has almost entirely been replaced by polyvinyl chloride today. Of course, high voltage cables still use clay for insulation because the temperatures on these high voltage cables can go up to a maximum of 250 degrees Celsius while the threshold for PVC is 105 degrees Celsius. For lower and medium voltage application though, polyvinyl chloride has already captured a large segment of the market.

Tests and experiments on different other compounds of PVC are going on to raise its resistance to electricity. The major advantage with PVC is that it is lightweight and easy to use. If the threshold levels rise enough to resist 250 degrees Celsius, high voltage cabling will undergo a major change for the better. It will not just improve project completion times but also bring in the durability factor which is missing in clay insulation. The other important factor that the introduction of PVC insulation in high voltage cables will bring about is cost effectiveness.

High Quality Glass Wire by Reputable Manufacturers

Glass wires are generally bare copper wires coated with a glass covering. This prevents oxidation of copper when it comes in contact with environmental pollutants. Such wire is also resistant to melting at high temperature; that’s why it is perfect for use in motors, electric heaters, and such appliances that use heavy power load.

Fiber glass wire

Electrical Power Cable: Components and Ratings

Do you know who developed the first power supply system? Let the answer light up like a bulb in your mind. Yes, it was Thomas Edison! He did it in New York City in 1882. He used copper rods, which were covered in jute and positioned in rigid pipes containing a bituminous compound.featurewireandcablescurrentaffairseptember2015

Well, the journey of an electrical power cable from then till now has been interesting with lots of changes, to be precise, improvements.

 Modern power supply

Modern cables for power supply are available in various types, materials, and sizes. Each one is designed based on the usage. Sometimes, big single insulated conductors are also known as cables in the electrical industry.

 Components of electrical power cables

There are 3 chief components:

  • Conductors
  • Insulation material
  • Protective layering

The design of each cable varies depending on its application.

How a cable is designed and what material is used depends on:

  • Current carrying capacity of the cable – It determines the conductor’s cross-sectional size.
  • Working voltage – It determines insulation thickness.
  • Environmental conditions – They include temperature, mechanical force on cable, exposure to chemicals and sunlight, and exposure to water. They determine type and composition of outer protective layering.

 Short circuit rating

Usually, size of conductor required for power supply inside cable is determined more by its capacity to transfer short circuit current than by its capacity to transfer sustained current. This is because during a short circuit a sudden gush of electric current passes for a few cycles. This is followed by a steadier current flow. The period ranges generally between 0.1 to 0.3 seconds. This is where the importance of material used to create electrical power cable comes to play. The material should withstand the sudden gush of current with minimum or nil damages or hazard.

 Current carrying capacity and voltage drop

The capacity to carry current answers the question as to what size of conductor should be. It is the highest permissible rise in temperature that dictates the safe current carrying capacity of a cable, especially an underground one.

Voltage drop determines design of conductor for a power cable. Manufacturers consider the maximum permissible drop in voltage from source to load to design a cable conductor.

Here, Ohm’s law comes to play that states that current passing between two points in a conductor is directly proportional to voltage present across both points.

Choice of material is important here. Undoubtedly, copper is the best choice to manufacture electrical power cable. Copper wire is an efficient conductor and features lower voltage drop for a particular size and length than aluminum wire. Again, larger sizes of wire show lesser voltage drop than smaller sizes with the same length.

While choosing a cable you must know power requirements, application, voltage conditions, and such things. These will determine what type of cable will suit your electric power needs. Reputable manufacturers like Rajasthan Electric provide excellent wires and cables that are tested to the core and produced keeping in mind quality standards. You can also get braided connectors, tin coated copper wires, enameled copper strips, nickel copper wires, and more from them.

Benefits of Using Braided Flexible Connectors

Braided flexible connectors are used primarily for the purpose of passing currents through unstable conducting equipment. This is because the conductivity and location of many devices keeps changing as a result of conditions like thermal expansion or vibrations or simple operational movements. This is why braided flexible connectors made from copper are found to be very useful.Braided Flexible Connectors

These braids of copper wires are made for establishing connections between very big components. The smaller wires which make up the copper braids are seen to be resistant to breakage even under repeated movements and vibrations unlike larger wires. These braids are made from braided strands of metals which are placed around the central cable. When you place orders for the braided connectors, the manufacturers will design them depending on your specifications.

Why are braided flexible copper connectors useful?

The braided flexible connectors are very important parts of the electronics industries. These are prepared using copper and stainless steel. This is usually done to offer additional support and strength. The main purpose of such wires is to give maximum power outputs.

So, for those sectors where demands for power are higher and wires are likely to undergo a lot of load, the braided flexible connectors are preferred. They are cost-effective solutions which guarantee maximum output of power. They can successfully control the vibrations and absorb these. They handle the compression and expansion of wires when power is being transmitted through these. They can be custom designed to regulate machine-delivered vibrations. So, you will see that these connectors find a lot of use in electrolytic processors, transformers, computers, and power generators.

The communication and planting industry also makes use of such connectors. To choose manufacturers of these connectors, it is best to read online reviews about the products first and compare prices of the products quoted by multiple vendors.



Submersible Winding Wire – Uses, Features, & GST

Submersible winding wire is used in wide array of industries especially in submersible pumps. Highly pure electrolyte grade copper is used in manufacturing these wires. There are many renowned manufacturers of these wires that maintain high standards for creating extra softness in annealed conductors.Submersible Winding Wire

These submersible winding wires play extremely important role in proper functioning of heavy motors, where slightest quality issue or any kind of defect can lead to creation of big issues in the entire set-up. If there are any issue in the submersible winding wire then that may also lead to failure of pump during extremely important operations. That is the reasons why the leading manufacturers of such wires take into account all the possible failure issues so that at the time of manufacturing all the probable issues can be avoided.

In fact, numerous tests are conducted on the wire so that these wires have flawless quality. Some of the tests performed on these wires before releasing them in the market include elongation test, spring back test, melting point test, spark test, thermal ageing in air test, heat shock test, and many more.


Submersible winding wire comes with numerous features and properties that make this the preferred choice of submersible pumps. Some of the features are listed and discussed below –

• Most important properties of these wires include chemical, thermal, mechanical, and electrical properties, which ultimately help in withstanding abrasions and frictional losses. Biaxially oriented synthetic film is used in production of insulating material. This material is then placed concentrically around the conductor. This has been seen to have a very high life.

• Tensile strength of these submersible winding wires is extremely high, which again supports at every point of the wire where excessive stretching takes place.

• Overall diameter of these wires is less than that of the conventional PVC winding wires. This makes the former easier to wind. That’s why submersible winding wire is preferred and so predominantly used in motors.

• With easier winding facility of the wire, the motor size of the pump also gets reduced. In fact, this facility helps in development of smaller pumps, which ultimately saves the costs of materials, stamping, and castings. It has been seen that these facilities save up to 25 per cent in cost of pumps.

• There are many other properties and features associated with the submersible winding wires. Some of them are dielectric strength, ability to withstand 130°c temperature for a short period of time or -60°C to 105°C continuously, less leakage of current, tear resistant, and more mechanical strength.

How GST Affects Submersible Winding Wire?

After the first government’s announcement of the GST rates, the lighting industry was apprehensive. Though there were revision of rates on June 3 and June 11, confusion persisted due to the presence of multiple lists as well as categorisations. However, the confusion was done away with in the 14th Goods and Services Tax (GST) Council Meeting, where it was clearly mentioned that the winding wires, LED lights/fixtures, Metal Core Printed Circuit Board panels, LED driver, and many more come in the 18 per cent rate bracket, much lower than the earlier proposed 28 per cent rate. After this announcement, it has been decided that no price increase will take place in the GST regime.

Braided Connectors – Utility And More

Braids manufactured suing many wires are, at times, used for flexible electrical connections between various large components. Braids score over large single wires in such cases since the many small wires in them are more resistant to breaking or chafing under constant pressure, like repeated motion or vibrations.
Braided connectors are manufactured using copper or stainless steel bellows. They are sometimes covered to offer enhanced support and strength. These are vital components of the electronics industry.

Connectors are used to join electrical circuits that are used as interface. It is the delicacy of the operationalnature of these connectors that force the manufacturer to be very careful when it comes to using precise calculations and configurations.

The most common metal used to make these connectors is copper. This is because copper has excellent thermal and electrical conductivity, a feature that makes it the perfect choice for making these connectors.

What these connectors do

The main purpose of braided connectors made by the leading providers in the industry, such as Rajasthan Electric Industries, is to deliver maximum output. These connectors have to do so even during times of peak performance.

The demand for power in the electrical sector is considerable and wires experience robust loads. Braided connectors are the most efficient solution to ensure optimal power output in such cases.

Here are some benefits of using these connectors:

•  They absorb and control the vibrations.

•  They provide minimal resistance to ensure seamless productivity.

•  During the transmission of power, they manage and control the natural expansion and compression of the electrical wires.

Some applications of these connectors are in the energy industry for generators, circuit breakers, transformers, wind turbines, etc. They are also used in other sectors such as military, aerospace, information technology, and more.

Low down on Copper Flexible Connectors and its types

Copper Flexible Connectors are used to transmit current across conducting mediums. These can be subjected to different motions, such as vibration, thermal expansion, or operational movement. These connectors have excellent flexibility, and provide maximum conductivity with minimum volt drop. While they are usually supplied in a non-insulation design, but if the customer so wants, they can be supplied with insulation sleeves of PVC, silicone, fiberglass, heat shrink, etc.
Laminated connectors

Some manufacturers also make laminated Copper Flexible Connectors. These are made by stacking multiple foils of electrolytic copper which is then pressed while high current is applied to it. A very special type of metal diffusion takes place. The metal melts and forms harmonized bonds. This gives an extremely negligible drop across the connector which helps increase its current carrying capacity and reduces its temperature rise.

No other metal is utilized in the process as the filler material to join the two layers together. There is a constant cross-section across the entire length of the connector. Also, it is possible to saw, drill, meld, and mill the contact areas of the connector without facing any issues.

These are built to customer specifications. They are used when an electrical connection has to be made in extreme conditions or environments, such as space constraints, low movements, low mechanism vibrations, etc.

These connectors are utilized as flexible expansion joints to connect bus-bars in industries such as power plants, switchgear units, etc. Most manufacturers offer these connectors in specifications set by the client and can completely customize the product according to their needs.

Braided connectors

Flexible braided connectors are manufactured using copper wire of any diameter as is specified by the client. They can be made by using bare, tinned, or silver-plated copper. The contact areas are pressed with bare copper connectors. These can be plated with tin or silver if the client so requires. For perfect conductivity, the ends can be dipped in hot tin.

These are for low and medium voltage applications only. They are used in the electrical industry in generators, wind turbines, rectifiers, substations, transformers, etc. These are used in conditions such as space paucity, heavy mechanical vibrations, thermal contraction/expansion of attached units, etc.

The Best Uses Of Copper Wire

Copper and its alloys are used in a huge variety of ways, right from common household wiring to marine vehicles. This is because copper has several excellent properties that make it so valuable in many industries.
Some of these are:

•    Malleability

•    Resistance to corrosion

•    Conductor of electricity

•    Ductility

•    Solderability

Many forms of copper such as solid or stranded bare copper wire, copper wire cables, and plated copper wire are manufactured by leading manufacturers, such as Rajasthan Electric Industries, today and are used in a staggering variety of industries, such as electrical, transport, construction, and more. The best part is that not all uses of copper are for conducting electricity and thus it is quite a useful and valuable metal.

The best uses of copper in wire form

These are:

Running electrical currents in buildings – right from small fixtures to major appliances, copper wires are used to carry electricity. They are considered the best since they are corrosion resistant and extremely durable. Finely twisted copper wires are utilized in ADSL and HDSL wiring for LANs.
