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.
