Tension Polymer Insulator
Tension polymer insulator consists of an insulating core-fiberglass rod protected by a housing (HTV Silicone Rubber) intended to be mounted rigidly on a supporting structure by means of a pin passing up inside the housing which is moulded or cast by circumferential crimping process.

Tension polymer insulator adopts the most advanced cylindrical head structure in the world, which is characterized by small head size. Light weight, high strength and large creepage distance. It can save metal materials and reduce the cost of the line. In order to meet the needs of live working, the traditional structural shape of the domestic is adopted on the brim.
