Product Description
Composite Wall Bushing

FCGW series of composite insulator dry wall drivepipe is implied to indoor or outdoor power substation with AC power system's rated voltage lower than 35KV, frequency being 50Hz, it performs electric insulator and mechanic support function for high-voltage conductor when high-voltage conductor crosses through wall or other object of connection to land, the product also is used as insulator and support for 10KV vacuum circuit breaker's high-voltage entry-exit wire. Especially, it is implied to dirty district for preventing from dirty-flash accident, therefore, it has been the upgraded product for vastly used china wall drivepipe.
Product Description
Wall Throught Composite Polymer Bushing Insulator
1.Professional Manufacture of China
2.Multi protection functions
3.CE,FCC,LVD&ROHS reports
Product Description
Condition of Use:
1. Ambient air temperatures within the range of -40 degree Celsius to +40 degree Celsius;
2. Altitude above sea level not exceeding 1, 000m; (If the altitude is higher than 1, 000, it needs adjust. )
3. Frequency of A. C. Power supply not exceeding 100Hz;
4. The mechanical load no more than the rated value.
This series product are composed of silicon rubber for sheds/ housing, glass-fiber reinforced epoxy resin rod core and hop DIP galvanized metal fittings. It has good mechanical performance and electric performance compared with porcelain insulators.
This product uses the capacitor equalizing theory; it uses optimal structural design by special electric field analysis andcalculation; it is light and handy, and it is convenient for installation.The product is made of fire resistant and corrosion resistant material without oil or porcelain. It not only can be used in thecity with high sanitary requirement, but also can be used in the area with severe pollution.This series product consists of primary coil, bushing flanges, and terminal block etc components.The end shield or ground shield is lead out separately to be convenient for test, and it also has good humidity resistance.The insulation resistance is stable and reliable.The secondary terminal block is formed by casting as a whole, it can prevent from turning, so the insulation resistance is stable and reliable.
Wall bushing is used for the power station and substation distribution equipment and high-voltage electrical appliances, for the wires through the ground partitions, walls, or electrical equipment enclosure to support the conductive part to make it right or housing insulation. 
according to their use of the environment it can be divided into indoor and outdoor wall bushings. Through the center of the conductor can be divided into the bus ceramic wall bushings, copper conductor wall bushings and aluminum conductor wall bushings. 
When the copper conductor and the bus is directly connected, it's very easy to produce galvanic corrosion, the contact surface temperature is too high cause the joints to burn, affecting the life of the equipment, it should be using copper and aluminum transition joints, but to cause trouble for construction, the use of aluminum conductors porcelain The casing can solve these problems. 
Indoor and outdoor wall bushings are made by porcelain pieces, conductive rod, both ends of metal accessories and mounting flange assembled. Bus wall bushing is made by the porcelain pieces, both ends of the metal accessories, bus plywood and mounting flange assembly (bus plywood usually with bus size by the user).
