Pin insulators are designed to provide line support. The functions of these insulators is to support the conductor directly on the head or neck of the insulator (top and side grooves). Our pin insulators are designed and manufactured by BS standard for insuring the insulators' electrical and mechanical performance, as well as all dimensionalspecifications and requirements.
