Din Pin Type Insulators For High Voltage Supplier China

Din Pin Type Insulators For High Voltage

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 DIN standard for insuring the insulators' electrical and mechanical performance, as well as all
dimensionalspecifications and requirements.
