The porcelain bushings are used extensively in electrical apparatus. Porcelain bushing is the device that enables one or several conductors to pass through a partition such as a wall or tank and insulates the conductors from it. The means of attachment to the partition, such as flange or other fixing device, forms part of the bushing.
Big porcelain bushing, hollow insulator upto 1000kv:
Upside down transformer bushing
Capacity voltage transformer bushing
Sf6 current transformer bushing
Outdoor cable end bushing
Voltage transformer bushing
Current transformer bushing
Circuit breaker post bushing
Sf6 transformer bushing
Oil immersed voltage transformer bushing
Sf6 circuit breaker bushing
Electrostatic precipitator bushing
Small porcelain bushing, hollow insulators are used as the insulating elements such as the transformer bushings and wall bushings .They are designed to perform under outdoor and indoor conditions for voltage upto 36kv.
