Porcelain Support Insulator

We are indulged in exporting Porcelain Support Insulator that are also called Porcelain Bushing, or Support Bushing is used as high-voltage insulating and sealing through which the discharge electrode suspension rod entering the electric field in an ESP, and in small size ESP it also functions as supporting of the discharge electrode system. By its configuration, it is classified into three types: Cylindrical insulator, conical insulator and special-shaped insulator.

Porcelain Bushing is glazed white or brown on surfaces inside and outside with both ends ground.
The XHDC Porcelain Bushing conforms to the Chinese standards of GB/T772-2005 a Technical specifications for high-voltage insulator' and JB/T6746. (1-4)-1993 a Ceramic insulator used in electrostatic precipitator ', and the IEC series standard is also followed.

With different materials XHDC Porcelain Bushing can be used under the temperature a 250A C or a 350A C with the operating voltage ranging from 72kV to 120kV and a mechanical compressive failing load not less than 500kN.
