Thumela i-imeyileIintambo ezihlanganisiweyo zomoya zeMedium Voltage zisetyenziselwa ikakhuluimigca yesibini ephezulukwiipali okanye njengezondla-manzi eziya kwiindawo zokuhlala. Ikwasetyenziselwa ukudlulisa umbane ukusuka kwiipali zombane ukuya kwizakhiwo. Ibonelela ngokhuseleko oluphezulu nokuthembeka, imelana neemeko zemozulu ezinzima, imitha ye-ultraviolet, kunye noxinzelelo loomatshini. Kulula ukuyifaka nokuyilungisa, ngeendleko zokusebenza eziphantsi, isetyenziswa rhoqo ekusasazweni kombane kwiindawo zasezidolophini nasemaphandleni.
