Policlain Insulator gas Bushing
The porcelain insulator type of gas bushing has a porcelain cylinder and contains high insulating gas. The insulating voltage is from 70kV to 1000kV, and the current rating is applicable upto 12000A. This is the most commonly used type of bushing.
Composite Insulator gas Bushing
The composite insulator type of bushing has a silicon rubber coating on the surface of the FRP (Filament Reinforced Plastic) cylinder, and also contains high insulating gas. It is paticulary suitable in regions where more severe earhquakes may be expected. We can provide this type of bushing with voltage ratings up to 550kV, and current rating of 6000A.
300kV - GCB applied composite Insulator gas bushing.
500kV - One - break GCB applied composite Insulator gas bushing.
