、The scope of application and use
The cotton weft woven copper belt mainly used for dressing electrostatic ring, supporting tube and slope adjustment etc. it consists of conductive copper fiber. Longitude 0.1MM copper wire flat rolling and latitude, by using 80 S cotton fibers， 2 shares of dark colored cotton fiber.
The main performance indexes of bare copper wire
