--- Isiguquli sokusabalalisa esingu-22 kV sidlala indima ebalulekile ohlelweni lokusatshalaliswa kukagesi, isebenza njengebhuloho phakathi kwemigqa yokudlulisa ama-voltage kakhulu nokusetshenziswa kwamakhasimende okuphansi. Lawa ma-transformer aklanyelwe ukukhipha amandla kagesi kusuka ku-22 kV kuya emazingeni aphephile futhi asebenzise izinhlelo zokuhlala nezohwebo, Ngokuvamile kusuka ku-400 V kuye ku-1 kV. Ukuqonda ubuchwephesha
