Iyunithi yebhizinisi Yokudluliswa Nokusabalalisa Amandla (T/D) ithuthukisa amasistimu okuxhumana amaswishi aqinile futhi amelana kakhulu nezinga lokushisa. Amakhasimende ethu asebenzisa lezi zinhlelo ukulawula ama-voltages afinyelela ku-1 200 kilovolts nama-currents afinyelela ku-50 kiloamp. I-Arcing ikhiqiza amazinga okushisa afinyelela ku-20 000 °C. Lapho izinsimbi ezivamile zingahluleka khona, i-tungsten-copper (WCu), i-copper-chromium (CuCr) ne-tungsten carbide-silver (WCAg) igcina ikhanda elipholile.
Ukushintsha othintana nabo abenziwe nge-tungsten-copper kuthenjelwe kukho ukuphazamisa nokuxhuma isekethe kagesi ngisho nasezindaweni eziphakeme.
Okungashabalali: Ngokumelana nokuguga okuphezulu kanye nezindawo zokuguguleka kwe-arc, oxhumana nabo be-arcing bangafinyelela impilo yesevisi engaphezu kweminyaka engama-40.
Balungele ukufakwa: Oxhumana nabo bebodwa abanele - sihlanganisa futhi sixhuma zonke izingxenye ezidingekayo zothintana naye weswishi egudlukayo negxilile futhi sikunikeze isistimu yokuxhumana ephelele elungele ukufakwa.
