Bolted Flexible Connection for Precision Current Transfer and Mechanical Movement Compensation
Product Introduction
Flexible Bare Copper Busbar is a reliable electrical connection component designed for precision current transfer and mechanical movement compensation in modern power systems. Manufactured from high conductivity copper, it provides an efficient conductive path between electrical components while allowing controlled flexibility during equipment operation.
The bolted connection structure combines secure mechanical fastening with flexible copper construction. This design is particularly useful when connected components experience small movements caused by vibration, thermal expansion, equipment adjustment, or installation tolerances. Flexible Bare Copper Busbar can accommodate these conditions while maintaining a stable electrical connection when correctly selected and installed.
The product can be customized in length, width, thickness, terminal configuration, mounting hole position, and conductor structure. This allows manufacturers and electrical engineers to integrate the connection into different equipment layouts without significantly changing the original system design.
Product Applications
Flexible Bare Copper Busbar is suitable for electrical systems that require dependable current transfer together with mechanical flexibility. The bolted connection method makes it practical for equipment where secure installation and convenient maintenance are important.
Typical applications include switchgear, power distribution cabinets, transformers, battery energy storage systems, power conversion equipment, industrial control panels, electrical machinery, renewable energy systems, charging equipment, and power electronics.
It can also be used to connect batteries, terminals, copper conductors, power modules, grounding points, and other current carrying components. In compact electrical assemblies, its flexible structure can help compensate for positional differences and simplify connection routing.
