Copper braided wire soft connection

Copper braided wire soft connection is to use copper braided wire as conductor, both ends of the selection of copper tube, copper tube surface tin plating disposal, joint standard according to customer needs to produce, and then through extra disposal, make soft connection, soft grounding. High conductivity, anti-fatigue ability. Mainly suitable for all kinds of high-voltage electrical appliances, communication equipment, vacuum electrical appliances, mine explosion switches and automobiles and other related products to do soft connection. The soft connection of copper braided wire is suitable for all kinds of high-voltage electrical appliances, vacuum electrical appliances, mine explosion-proof switches, automobiles and locomotives. The soft connection of tinned copper braided wire is mainly used in places where the safe use of electrical appliances is damaged due to expansion, vibration and other factors. The braided wire is not as good as the transition of copper bus bar, and the bus bar connection at the outlet of generator can also be used for grounding, such as cable grounding.
