What Are the Benefits of Bunched Copper Wire?

Almost all electrical and industrial applications use copper wires in homes and other commercial places. The copper wires are made in different varieties and though they retain the properties of copper, many of them differ in their features and functions. One variety is bunched copper wire. This type of wire is a cluster of wires and can be more strong and reliable than the bare copper wire.  When bunched together they can allow a smooth and sturdy connection enhancing the application.

How is the bunched copper wire used?

Bunched Copper Wire.

The Bunched wires are used in a major way in the cable industry. The cables connect different electrical processes, can be tied together and used as a rope for tying knots for use in different appliances.

The winding, looping or binding is done around different types of rods based on the nature of use. They are flexible and can be looped in half-frame or semi-concentric arcs.

The wire is also used in the aeronautical industry in the manufacturing of space shuttles, radio transmission devices, cockpit circuit machinery, and maritime engineering.

Features of bunched copper wire

  1. These wires are highly practical, hard and strong and users can benefit with its long service life.
  2. They are supple and can be customized to suit individual needs. It can be molded into any shape and form as per the specific requirements of the users.
  3. The bunched wires are more elastic than the bare copper wire and offer high tolerance without losing its shape easily. It is applied for joining two appliances and used in a loop form whenever the wire needs to be bent and designed into different shapes.
  4. They do not lose their electromagnetic properties while under use. They are can provide the highest level of precision with zero tolerance. They can be seen in use in industries like defence, aerospace, marine, pharmacy, biometrics in addition to the electric and electronic devices. The inaccuracy levels in the bunched wires are lower than 0.03%

Superior in quality:

One can easily know the difference when bunched copper wire is not used in an application. The bare wires are likely to break easily if they are applied continuously while when in a bunch, they are much sturdier and durable.

This wire like all other copper types is a good conductor of electricity and the wires are capable of dispersing energy at a faster pace. Although silver is superior in its conducting, it is not used much since it is expensive.

Another flexibility of a type of copper is the braided copper rope. It can be used as a rope without twisting. The braided rope is made by joining strands of rope. The strength and diameter increases when there is an increase in the number of strands. The rope wire is anti-abrasive and carries many anti-corrosive properties. The wires are clamped firmly on one end and braided together. The braiding can be in sets of 3,5, or more strands. Once the desired length is reached with firm braiding, the loose ends are secured.  To ensure quality and safety, the manufacturing is done by professionally trained technical experts.

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.
