Copper brush wires are high-flexibility conductors specifically designed for flexible connections in motors, electrical appliances, and instrument circuits. They are especially suitable for AC or high-frequency current applications. GRL copper brush wires are manufactured from ultra-soft T2 copper wires, twisted to provide exceptional conductivity and flexibility, meeting the GB/T12970.4-2009 National Standard of China.

Copper brush wires are primarily used for flexible electrical connections in motors, appliances, and instrument circuits. They are particularly effective in applications requiring high conductivity and frequent movement or bending, such as in industrial machinery and automation systems.
Tin-plated copper brush wires offer enhanced resistance to oxidation and corrosion, making them more durable in harsh or corrosive environments. The tin layer also improves solderability, which can benefit certain electrical installations.
The diameter of the copper strands affects both the flexibility and current-carrying capacity of the wire. Thinner strands provide higher flexibility, while thicker strands increase the current-carrying capacity. Choosing the right diameter depends on the application’s specific requirements, including space constraints and electrical load.
Yes, our copper brush wires are highly customizable. You can specify the cross-sectional area, outer diameter, wire structure, and surface treatment (bare or tin-plated) to meet unique application needs. Please get in touch with us for tailored solutions.
In the new energy sector, copper brush wires are commonly used in battery connections, inverters, and other high-current, flexible connection points. Their high conductivity and flexibility make them ideal for renewable energy systems, such as solar and wind power installations.
Copper brush wires are constructed with twisted strands, which help reduce skin effect losses in high-frequency AC applications. This makes them suitable for high-frequency circuits where efficient energy transfer and minimal losses are crucial.
