What Is a Copper Flexible Connection?

A copper flexible connection is a conductive component designed to carry electrical current while allowing movement,

vibration absorption, thermal expansion compensation, and mechanical stress relief. It is commonly made from high-purity copper strands,

Copper braids, or laminated copper foils, and it is used wherever rigid conductors are not suitable.

In simple terms, a copper flexible connection acts as a bridge between two electrical points that may move relative to each other

or experience heat-related expansion. Unlike rigid copper bars, flexible copper connectors can bend, twist, and adapt to installation

requirements without losing electrical continuity. This makes them highly valuable in systems that require both conductivity and flexibility.

The term copper flexible connection is often used interchangeably with:

• Copper flexible connector
• Copper braid connector
• Flexible copper shunt
• Flexible copper busbar connection
• Flexible grounding connector
• Laminated flexible copper link
