Thumela i-imeyileIintambo zamandla ze-12.7-22kV-XLPE ezigqunywe nge-insulated medium-voltage zihlala zisetyenziselwa iinethiwekhi zokusasaza umbane kunye neentambo zamandla ezincedisayo kwiindawo ezahlukeneyo. Izixhobo zokukhusela ezihlanganisiweyo zivumela ukungcwatywa ngokuthe ngqo ukuthintela ukutshayiswa kombane ngengozi kunye nomonakalo. Uhlobo lwe-AS/NZS 12.7-22kV-XLPE luquka iintambo zamandla ze-medium-voltage ezenziwe ngokwe-Australian/New Zealand Standard AS/NZS 1429.1. Zifanelekile ukufakwa okuzinzileyo kwiinethiwekhi zombane kwiindawo zangaphakathi nangaphandle, kwaye zinokufakwa kwiipayipi zekhebula, kwiitreyi zekhebula, okanye zingcwatywe ngqo phantsi komhlaba. Zifanelekile kwiinkqubo zamandla anamandla aphezulu afikelela kwi-10kA/1 second. Izakhiwo ezinezakhono zamandla anamandla aphezulu ziyafumaneka xa ziceliwe.

Iintambo zeMedium Voltage ezenzelwe wena:
Ukuze isebenze kakuhle kwaye ihlale ixesha elide, intambo nganye ye-MV kufuneka ilungiselelwe ukufakwa kwayo kodwa kukho amaxesha apho kufuneka intambo eyenzelwe wena ngokwenene. Iingcali zethu zentambo ye-MV zingasebenza nawe ukuyila isisombululo esihambelana neemfuno zakho. Ngokwesiqhelo, ukwenza ngokwezifiso kuchaphazela ubungakanani bendawo yesikrini sesinyithi, esinokulungiswa ukuze kutshintshwe umthamo wesekethe emfutshane kunye nezibonelelo zomhlaba.
Kuzo zonke iimeko, idatha yobugcisa inikezelwa ukubonisa ukufaneleka kunye neenkcukacha eziphuculweyo zokwenziwa. Zonke izisombululo ezenzelwe wena ziphantsi kovavanyo oluphuculweyo kwiZiko lethu loVavanyo lweeCable zeMV.
