CB-10KV 200A-1500A Indoor Copper Conductor Wall Bushing

Introduction of 10kv wall bushing

High-voltage wall bushing (hereinafter referred to as bushing) is suitable for rated voltage (10-35) kV, frequency (15-60) Hz three-phase AC system power station and substation power distribution device, for the conductive part to pass through the insulation panels, walls or
Other grounding objects are used for the fixed connection between the insulation support and the external conductor (bus bar).

Environmental conditions

1) Indoor Wall Bushing
Ambient temperature not higher than +40°C, not lower than -40°C
The altitude does not exceed l000m
The monthly average relative humidity is not more than 90%
The surrounding air should be free from obvious pollution such as corrosive or combustible gas, water vapor, etc.
No frequent violent vibration

2) Outdoor Wall Bushing
The ambient temperature is not higher than +40°C and not lower than -40°C;
The altitude does not exceed l000m;
The wind speed is not more than 34m/s
According to GB/T5582, the air pollution degree of the environment where the product is used is divided into 4 levels: Ⅰ, Ⅱ, Ⅲ, and Ⅳ;
No frequent violent vibration

Product Features

The wall bushing is composed of porcelain parts, metal accessories, mounting flanges and conductive bars (rods).

Use and classification

Porcelain wall bushings are used for power distribution devices and high-voltage electrical appliances in power stations and substations, for wires to pass through grounding partitions, walls or electrical equipment enclosures, and to support conductive parts to insulate them from the ground or the enclosure.
Porcelain wall bushings can be divided into indoor and outdoor types according to their use environment.

According to the different conductors passing through its center, it can be divided into busbar wall porcelain bushing, copper conductor wall porcelain bushing and aluminum conductor wall porcelain bushing.
When the copper conductor is directly connected to the busbar, galvanic corrosion is likely to occur, and the temperature rise of the contact surface is too high, which will cause the joint to burn out and affect the life of the equipment. Therefore, copper-aluminum transition joints should be used, but it will bring trouble to the site construction.
The conductor porcelain wall bushing can solve the above problems.
Indoor and outdoor wall bushings are assembled from porcelain parts, conductive rods, metal accessories at both ends and mounting flanges. The busbar through-the-wall porcelain bushing is assembled from porcelain parts, metal accessories at both ends, busbar splint and mounting flange (female
The splint is usually prepared by the user according to the size of the busbar).
