Copper braided connection wire for battery housing

Copper Braided Connection Cable for Battery Enclosures

Product Overview

The copper braided connection cable for battery enclosures is a flexible connector specifically designed for energy storage and new-energy vehicle battery systems. It is crafted using a multi-layer ultra-fine copper wire braiding process, offering exceptional flexibility and excellent vibration resistance. The outer layer is equipped with a heat-shrinkable insulating sleeve, effectively preventing oxidation of the copper wires. This product meets the standard requirements of leading energy storage companies such as CATL, and is primarily used in high-voltage inter-chamber transitions within battery enclosures and equipotential grounding applications in energy storage modules. It addresses the industry’s longstanding pain points—such as traditional rigid harnesses being prone to breakage under rough road conditions and occupying excessive space when bent—while also simplifying the enclosure structure, reducing assembly time by 30%, and providing efficient, reliable battery system connection solutions for energy storage PACK manufacturers and new-energy bus OEMs.

Core Structure and Performance Principles

The key advantage of this connection cable lies in its multi-layer ultra-fine copper wire braiding structure. Compared to conventional rigid harnesses, the multi-strand braiding design significantly enhances flexibility, enabling large-angle bends. During vehicle operation, it effectively absorbs vibrations and impacts from road irregularities, preventing cable breakage caused by the rigid stress of hard connections. The outer heat-shrinkable insulating sleeve not only provides insulation and protection but also isolates the cable from external moisture and corrosive substances, preventing copper oxidation and extending the cable’s service life while ensuring stable electrical conductivity over long-term use. Additionally, its braided conductive path is more optimized, capable of carrying high currents without significant temperature rise, thus meeting the high-power transmission demands of battery systems.
