Thumela i-imeyileI-6/10kV XLPE-i-insulated medium-voltage cable cables zilungele uthungelwano lwamandla olufana nezikhululo zombane. Zinokufakwa kwiiconduits, phantsi komhlaba, nangaphandle, kunye nakwiindawo eziphantsi komatshini wamandla angaphandle. I-conductor isebenzisa ukugquma kwe-XLPE, inika ukuxhathisa okusemgangathweni kwe-thermal kunye nokuxhathisa ukubola kweekhemikhali, ngaloo ndlela ivumela ukusetyenziswa kwimizi-mveliso yeekhemikhali kunye neendawo ezingcolileyo. Isikrweqe socingo lwe-aluminiyam (AWA) yeentambo ezingundoqo kunye nentsimbi yesikrweqe socingo lwentsimbi (i-SWA) yeentambo ezininzi zibonelela ngokhuseleko lomatshini olomeleleyo okwenza ezi ntambo ze-11kV zilungele ukungcwatywa ngokuthe ngqo emhlabeni. Ezi ntambo zombane ezixhobileyo ze-MV zixhaphake kakhulu zibonelelwa ngezikhondatha zobhedu kodwa zikwafumaneka nezikhondaktha zealuminiyam xa zicelwa kumgangatho ofanayo. Abaqhubi bezobhedu baxinzelelwe (iKlasi 2) ngelixa abaqhubi be-aluminium bahambelana nomgangatho usebenzisa ulwakhiwo oludibeneyo kunye noluqilima (iKlasi 1).

2.I-Insulation
Iployethylene (XLPE) eyongeziweyo eqhagamshelweyo ilungele ukusebenza kwiqondo lobushushu le-conductor elingama-90°C.
3.I-Insulation Screen
Ikhompawundi ye-semi-conducting eyongeziweyo isetyenziswe kumsebenzi ofanayo kunye nokugquma. Izikrini ezibandayo ezikhumulwayo zibonelelwa njengomgangatho kodwa izikrini ezibopheleleke ngokupheleleyo zinokubonelelwa ukuba zichaziwe.
4.Metallic Screen
Iiteyiphu zobhedu ezisetyenzisiweyo zigqithene ukunika indlela yangoku yempazamo yomhlaba.
5.Ukubeka phezulu
Iinqununu ezintathu ezibekwe kunye neefayili zentambo ye-polypropylene ukwenza intambo yetyhula edibeneyo, kwaye iboshwe nge-tape.
6.Tape Binder
7.Isingxobo
I-polyvinyl chloride emnyama eyongeziweyo (PVC) okanye i-Low Smoke ye-Zero Halogen (LSOH) ikhompawundi inikezelwa njengomgangatho. Iimathiriyeli ezizezinye zinokubonelelwa ukuba zichaziwe.
8.Izikrweqe
Umaleko omnye weengcingo zentsimbi ezizityhutyhayo.
9.I-Oversheath
I-polyvinyl chloride emnyama eyongeziweyo (PVC) okanye i-Low Smoke ye-Zero Halogen (LSOH) ikhompawundi inikezelwa njengomgangatho. Iimathiriyeli ezizezinye zinokubonelelwa xa zicacisiwe umz. i-medium density polyethylene (MDPE).
