Polymer Pin Insulator
      Composite pin insulator, also called polymeric pin insulator or polymeric line post 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.
      Our existing composite pin insulator ranges from 10kv to36kv, for higher voltage composite pin insulators, please kindly send us your specifications.
