Copper braided tape is used as conductor for soft connection, copper pipe is selected at both ends, silver plating is applied on the outer surface of copper pipe, and the joint size and fineness are produced according to the customer's needs. Then, through special treatment, it is made of soft connection, soft grounding, high conductivity, strong fatigue resistance, and can be produced according to the needs of customers. The soft connection of copper wire is made of high and low voltage electrical appliances, vacuum appliances, mine explosion-proof switches and automobiles, locomotives and related commodities for soft connection. The raw copper wire or tin plated copper braid wire is selected and made by cold pressing method. It can be tinned and silver according to the needs of users.

Copper braided tape flexible connection is generally used in non horizontal direction of live motion and low voltage circuit breaker as power components. The main electrical parameters of copper braided tape are DC resistivity (20 ℃) no more than 0.022 Ω mm2 / m, and DC resistivity (20 ℃) of tin copper braided belt is not more than 0.0234 Ω mm2 / m

Copper braided tape soft connection is widely used in power transmission and distribution lines. It can be seen everywhere in this circuit equipment and non-linear connection: the line that transfers power from step-down substation to distribution transformer or sends power from distribution transformer to electricity user is called distribution line. The voltage of distribution lines commonly used in China is 0.4kV, 6kV and 10kV, 6kV and 10kV are called high-voltage distribution lines, and 0.4kV are called low-voltage distribution lines. The construction of distribution lines needs to be safe and reliable, adhere to the continuity of power supply, reduce line loss, forward transmission power, and ensure excellent power quality. The conductor is the primary component of the line, and its function is to transmit current and power. Conductor classification: aluminum conductor, copper conductor, steel cored aluminum stranded wire, heat-resistant conductor, insulated conductor, carbon fiber conductor, Yinbao steel conductor, split conductor: a conductor erecting method used to restrain corona discharge and reduce line reactance for EHV transmission line. That is to say, each phase conductor is composed of several smaller diameter branch conductors, and each conductor is placed in a symmetrical polygon with a certain distance. Lightning conductor (ground wire) the primary function of lightning conductor is lightning protection, which is erected above the conductor.

Since the lightning conductor is erected on the top of the tower above the conductor and grounded at the bottom of each tower, the lightning conductor is also called overhead ground wire. (direct lightning / shielding lightning) raw materials: galvanized steel strand, steel cored aluminum stranded wire, aluminum clad steel strand, OPGW composite ground wire, 10kV line is not provided with lightning conductor, 35kV line is set with lightning conductor at 1-2km of substation exit, 110kV and above lines are generally provided with lightning conductor. Insulator insulator is used to support and suspend the conductor, and make the conductor and tower and other grounding parts constitute electrical insulation components. Insulator types: rod porcelain insulator, suspension porcelain insulator, suspension glass insulator and rod-shaped composite insulator. There are various kinds of fittings, fittings, fittings and so on. Tower tower is the support of supporting conductor, lightning conductor and other accessories.
