Iphepha ledayimane elinamachaphaza edayimane liyi-insulating material eyenziwe nge-cable paper njenge-substrate kunye ne-epoxy resin ekhethekileyo eguquliweyo efakwe kwiphepha lentambo kwimilo enechaphaza yedayimane.Ikhoyili inesakhono esihle kakhulu sokumelana noxinzelelo lwe-axial olufutshane;ukuphucula ukuchasana kwempembelelo esisigxina yekhoyili ngokuchasene nobushushu kunye namandla kunenzuzo kubomi kunye nokuthembeka kwe-transformer.
