I-insulator eyinhlanganisela, ebizwa nangokuthi i-polymeric pin insulator noma i-polymeric line post insulator, iqukethe induku yokuvikela i-fiberglass evikela indlu (i-HTV Silicone Rubber) ehlose ukufakwa ngokuqinile esakhiweni esisekelayo ngokusebenzisa iphini elidlula ngaphakathi izindlu ezibunjiwe noma ezifakwe ngenqubo yokuzungeza eyindilinga. impahla yomkhiqizo: I-insulator eyinhlanganisela yenziwa ngenduku yokuvikela, umkhono we-silicon rod glue kanye nakho kokubili ukuphela kokufakwa.
