Product Details

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.
