1. Phantsi{1}}Iiphaneli zoSasazo lweVoltage
Iiphaneli zokuhambisa amandla ombane asezantsi-ziiphaneli ezinomthamo olinganisiweyo we-1000V okanye ngaphantsi. Ngokuqhelekileyo zisetyenziswa kwiinkqubo zokusasazwa kwamandla kwiindawo zoshishino kunye nokwakhiwa, ukulawula nokukhusela imithwalo yombane.
2. Phakathi
Phakathi-Iiphaneli zokuhambisa i-voltage ziziphaneli ezinomthamo othelekelelwayo phakathi kwe-1kV kunye ne-35kV. Ngokuqhelekileyo zisetyenziswa kwizityalo zamandla ezincinci naphakathi{4}eziphakathi, izitishi, kunye nezinye iindawo, ukulawula nokukhusela inkqubo yamandla kunye nokusasazwa kwamandla kwimithwalo eyahlukeneyo.
3. Phezulu{1}}Iiphaneli zoSasazo lweVoltage
-Iiphaneli zokuhambisa amandla ombane aphezulu ziziphaneli ezinomthamo othelekelelwayo we-35kV okanye ngaphezulu. Ngokuqhelekileyo zisetyenziselwa kwiinkqubo zamandla amakhulu, ukulawula nokukhusela inkqubo yamandla kunye nokusabalalisa amandla kwimithwalo eyahlukeneyo.
