Electric brush wire is made by twisting copper wires with a single wire diameter of 0.05/0.07 or 0.1mm. Therefore, copper wire is extremely soft. Using this material, we can produce copper wires with large cross-sectional areas but smaller diameters. So, this type of copper wire can be applied to many devices, including small areas. This copper wire can also play a good role on moving parts. The advantage of small diameter and large cross-sectional area is further demonstrated in alternating current or high-frequency current.
Copper brush wire is a soft connecting wire used for connecting motor, electrical, and instrument circuits.
The product standard for copper brush wire is based on GB12970.4-91. The model of copper brush wire is TS copper brush wire; TSR copper soft brush wire.
The specifications of copper brush wires are: TS type (0.25mm-16mm) TSR type (0.6mm-6mm).
Twisting: The outermost layer of copper brush wire is twisted in the right direction, unless otherwise agreed by the supply and demand parties. The twisting direction of adjacent layers is opposite, and the twisting direction of the stranded wire is specified by the manufacturer.
Elongation rate: The elongation rate of TS type copper brush wire is not less than 18%; The elongation of TSR type soft copper brush wire should not be less than 15%.
Surface requirements: The surface of the electric brush wire should be smooth and free of any hair defects, such as golden yellow or light red caused by softening treatment
The colored surface can still be used as a qualified product.
