Ulwakhiwo:
Yenziwe kunye noHlobo oluvavanyiweyo lwe-AS / NZS 1429.1, IEC: 60502-2 kunye neminye imigangatho esebenzayo
Ukuqulunqwa - i-core 1, i-3 core
I-Conductor-Cu okanye i-AL, iSetyhula ene-Stranded, i-Stranded Compact Circular, i-Milliken iSegmented
I-Insulation - i-XLPE okanye i-TR-XLPE
Isikrini sesinyithi okanye i-sheath-Isikrini socingo lwe-Copper (CWS), i-Copper Tape Screen (CTS)
Isikrweqe – iAluminiyam yocingo oluxhotyisiweyo (AWA), ucingo lwentsimbi oluxhotyisiweyo (SWA), ipolyethylene (HDPE) yangaphandle – enye indlela
Ubukhulu beCable yeMV:
Iintambo zethu ze-10kV, 11kV, 20kV, 22kV, 30kV kunye ne-33kV zifumaneka kolu luhlu lulandelayo lobukhulu obunqamlezayo (kuxhomekeke kwiikhondaktha zeCopper/Aluminium) ukusuka kwi-35mm2 ukuya kwi-1000mm2.Iisayizi ezinkulu zihlala zifumaneka xa uceliwe.
