I-Triple insulated wire okanye i-insulated wire eqiniweyo eyenziwe ngamacandelo amathathu, ivala ngokupheleleyo iprayimari ukusuka kwisibini se-transformer.Ukugquma okomeleziweyo kubonelela ngemigangatho eyahlukeneyo yokhuseleko esusa imiqobo, iiteyiphu ze-inter layers kunye neetyhubhu zokukhusela kwi-transformer.
Inzuzo enkulu ye-triple insulated wire ayiyona kuphela i-voltage ephezulu yokuphuka efikelela kwi-17KV, kodwa Ukongeza ekunciphiseni ubungakanani kunye noqoqosho kwiindleko eziphathekayo zokwenziwa kwe-transformer.
