Product Description

ANSI 56-1 56-2 56-3 Porcelain Pin Insulator

Ceramic pin insulator have enough insulation strength and mechanical strength, type of electrical insulation can not only withstand the action of working voltage and overvoltage, but also have enough resistance to the erosion of chemical impurities, and type of insulations can adapt to the change of temperature and the influence of the surrounding environment.

Porcelain Pin Insulators are supplied complete with the steel spindle suitable for mounting on steel crossarm, both vertical and horizontal mounting, ceramic pin insulator shall be suitable for corresponding conductors. Threaded lead thimbles shall be cemented to the insulators to fix the Din Pin Insulators with required steel heads.
