Functions of copper braided belt
Copper braided tape is selected as the conductor, copper pipes are selected at both ends, and the surface of the copper pipes is silver plated. The size of the joints is produced according to the needs of customers. Then, through special treatment, they are made into soft connections, soft grounding, high conductivity and strong fatigue resistance. They can be produced completely according to the needs of customers. Soft connection of copper wire is used for soft connection of high and low voltage electrical appliances, vacuum electrical appliances, mine explosion-proof switches, automobiles, locomotives and related products. It is made of bare copper wire or tinned copper wire by cold pressing. It can be tinned or silver plated according to the needs of users.
Copper braided tape is widely used in power transmission and distribution lines. It can be seen everywhere in this circuit equipment and non-linear connection:
Transmission and distribution line
The line that sends the power from the step-down substation to the distribution transformer or the power from the distribution transformer to the power consuming unit is called the distribution line. The commonly used distribution line voltages in China are 0.4kV, 6kV and 10kV, and 6kV and 10kV are called high-voltage distribution lines; 0.4kV is called low-voltage distribution line. The demand for distribution lines is safe and reliable, the continuity of power supply is adhered to, the loss of lines is reduced, the power is transmitted forward, and the excellent power quality is guaranteed.
The wire is the primary component of the line, and its function is to transmit current and electric power.
Wire classification: aluminum wire, copper wire, steel cored aluminum strand, heat-resistant wire, insulated wire, carbon fiber wire, copper-clad steel wire
Bundle conductor: a conductor erection method used for ultra-high voltage transmission lines to restrain corona discharge and reduce line reactance. That is, each phase conductor is composed of several branch conductors with smaller diameter, and each branch conductor is placed in a symmetrical polygon at a certain distance.
Lightning conductor (ground wire)
The primary function of lightning protection wire is lightning protection, which is erected above the conductor. Since the lightning wire is erected on the top of the tower above the conductor and grounded at the bottom of each tower, the lightning wire is also called overhead ground wire. (direct lightning strike / round lightning strike)
Materials: galvanized steel strand, steel core aluminum strand, aluminum clad steel strand, OPGW optical cable composite ground wire
10kV lines are not provided with lightning protection lines, 35kV lines are provided with lightning protection lines 1 ~ 2km away from the substation exit, and 110kV and above lines are generally provided with lightning protection lines.
Insulator
Insulators are components used to support and suspend conductors, and to form electrical insulation between conductors and grounding of towers and towers.
Insulator type: rod-shaped porcelain insulator, suspension porcelain insulator, suspension glass insulator and rod-shaped composite insulator.
Hardware
The types of line fittings mainly include various wire clamps, connection fittings, connection fittings, protection fittings, pull wire fittings, etc.
tower
Poles and towers are supports for supporting conductors, lightning wires and other accessories.
Towers can be divided into straight-line towers, tension towers, corner towers, terminal towers, crossing towers and transposition towers according to their uses.
Poles and towers can be divided into wood poles, reinforced concrete poles, large bending moment poles, thin-wall centrifugal steel pipe poles, steel pipe poles, angle steel towers and high-strength steel pole towers according to materials.
