Hollow ceramic support insulator is used as high-voltage insulating and sealing through the discharge electrode suspension rod entering the electric field in an ESP. It also functions as support of the discharge electrode system. By its configuration.
Post insulator is used as high-voltage insulation for supporting HV Line. A post insulator consists of the ceramic body and metal fittings at both ends which are cemented together with binder that can withstand high temperature.
Shaft insulator is interposed and connected between the rapping shaft inside the electrical field and the driving gear-motor outside functioning as power transmission for turning the shaft and high voltage insulating between the discharge electrode system and the ESP casing.
