Flexible Braided Copper Busbar for Transformers - Customized Solutions from China Suppliers and Factory
The Features for Flexible Braided Copper Busbar
-
1. Excellent Electrical Conductivity
The raw material is oxygen-free copper wire with a purity of ≥99.9%. The electrical conductivity of copper is close to that of international standard soft copper (58 MS/m). After silver plating treatment, the electrical conductivity and oxidation resistance of some high-end products are further enhanced.
-
2. High Flexibility and Installation Compatibility
The braided structure of multi-strand copper wire endows the product with excellent bending performance, allowing for free adjustment of installation angles and effectively compensating for dimensional deviations during the installation of electrical equipment.
-
3. Strong Anti-Vibration and Anti-Fatigue Properties
Compared with rigid copper bars, the flexible structure of braided copper busbars can buffer the vibration and shock during equipment operation, reduce the fatigue loss of conductive components, improve the operational stability and service life of the electrical system, and has significant advantages under high-frequency vibration conditions.

Frequently Asked Questions (FAQ)
Our flexible braided copper busbars are made from oxygen-free T2 (C11000) copper wire with a copper content of ≥99.95%, ensuring excellent electrical conductivity and long-term reliability.
We offer four surface finish options: bare copper, tin plating, nickel plating, and silver plating. Silver plating provides enhanced electrical conductivity and superior oxidation resistance for high-end applications.
The flexible braided copper busbar supports a working temperature range of -50ºC to 120ºC, making it suitable for both extreme cold environments and high-temperature industrial applications.
Yes, all dimensions are fully customizable including length, width, thickness, hole number and sizes, cross sectional area, single wire diameter, plating type, bend angle, combined connectors, and high ampacity requirements — all tailored to your specific needs.
Unlike rigid copper bars, braided copper busbars offer superior flexibility, excellent vibration and shock absorption, and the ability to compensate for installation misalignments. This significantly reduces fatigue wear on conductive components and extends the service life of the electrical system.
Our flexible braided copper busbars comply with international certifications including RoHS, CE, and REACH, ensuring they meet global environmental and safety standards for use in a wide range of industries.
