Thumela i-imeyileIintambo zombane ezidityanisiweyo zombane eziPhakathi zisetyenziselwa ubukhulu becalaimigca ephezulu yesibinikwiipali okanye njengezondla kwizakhiwo zokuhlala. Ikwaqeshelwe ukuhambisa umbane ukusuka kwiipali zoncedo ukuya kwizakhiwo. Inika ukhuseleko oluphezulu kunye nokuthembeka, imelana neemeko zemozulu ezinzima, imitha ye-ultraviolet, kunye noxinzelelo lomatshini. Kulula ukuyifaka kunye nokugcina, kunye neendleko zokusebenza eziphantsi, isetyenziselwa ukuhanjiswa kwamandla kwiindawo zasedolophini nasezilalini.
Umgangatho:
IEC 60502-2---- Iintambo zamandla ezine-insulation extruded kunye nezixhobo zazo zombane ezilinganisiweyo ukusuka kwi-1 kV (Um = 1.2 kV) ukuya kwi-30 kV (Um = 36 kV) - Icandelo 2: Iintambo zombane ezilinganisiweyo ukusuka kwi-6 kV (Um = 7.2 kV) ukuya kwi-6 kV = 3 kV0
