Description:

Pin insulator is a component used to support or suspend a wire and form an electrical insulation between the tower and the wire. The ceramic parts of the pin-type ordinary ceramic insulator and the cast steel are glued together with cement glue, and the surface of the porcelain part is coated with a layer of glaze to improve the insulation performance of the insulator.

Ceramic porcelain pin insulator is used between the discharge electrode framework and ESP casing functioning as connecting and high-voltage insulating. By its own structure it is divided into two types: pure ceramic insulator and combined insulator.
