Thumela i-imeyileIintambo zombane ze-XLPE ezifakwe i-insulated ze-6/10kV zifanelekile kwiinethiwekhi zamandla ezifana nezitishi zamandla. Zinokufakelwa kwiipayipi zamandla, phantsi komhlaba, nangaphandle, kunye nakwiindawo eziphantsi kwamandla angaphandle oomatshini. I-conductor isebenzisa i-XLPE insulation, inikezela ngokumelana okuhle kobushushu kunye nokumelana nokugqwala kweekhemikhali, ngaloo ndlela ivumela ukusetyenziswa kumashishini eekhemikhali nakwiindawo ezingcolisiweyo. I-aluminium wire armor (AWA) yeentambo ezingundoqo kunye ne-steel wire armor (SWA) yeentambo ezingundoqo ezininzi zibonelela ngokhuseleko oluqinileyo loomatshini okwenza ezi ntambo ze-11kV zilungele ukungcwatywa ngqo emhlabeni. Ezi ntambo zombane ze-MV ezikhuselekileyo zihlala zinikezelwa ngabaqhubi bekopolo kodwa zikwafumaneka nabaqhubi be-aluminium xa ziceliwe kumgangatho ofanayo. Abaqhubi bekopolo baxinekile (iKlasi 2) ngelixa abaqhubi be-aluminium bethobela umgangatho besebenzisa zombini izakhiwo ezixineneyo neziqinileyo (iKlasi 1).

Isikrini somqhubi
Ikhompawundi ekhuphayo exutyiweyo ebotshelelwe kwi-insulation kwaye isetyenziswa ngendlela efanayo ne-insulation.
2. Ukuvala ubushushu
I-ployethylene edityanisiweyo (XLPE) ekhutshwe ngaphandle ifanelekile ukusebenza kubushushu bomqhubi obuyi-90°C.
3. Isikrini sokuvala
Ikhompawundi ye-semi-conducting ekhutshiweyo esetyenziswa kwindlela efanayo ne-insulation. Izikrini ezikhutshelwayo ezibandayo zinikezelwa njengezikrini ezisemgangathweni kodwa ezibotshelelweyo ngokupheleleyo zinokubonelelwa ukuba zichaziwe.
4. Isikrini sesinyithi
Iiteyiphu zekopolo ezifakwe zijikeleziswe ukuze kubonelelwe indlela yamandla ombane angasebenziyo emhlabeni.
5. Ukubeka phezulu
Ii-cores ezintathu zibekwe nge-polypropylene string fillers ukuze zenze intambo ejikelezayo encinci, kwaye zibotshwe ngeteyipu.
6. I-Tape Binder
7. Isingxobo
I-polyvinyl chloride emnyama ekhutshiweyo (PVC) okanye i-Low Smoke Zero Halogen (LSOH) compound enikezelwayo isetyenziswa njengesiqhelo. Ezinye izinto zingabonelelwa ukuba zichaziwe.
8. Ukuzikhusela
Umaleko omnye weentambo zentsimbi ezijikelezileyo ezifakwe i-galvanized.
9. I-Oversheath
I-polyvinyl chloride emnyama ekhutshiweyo (PVC) okanye i-Low Smoke Zero Halogen (LSOH) compound inikezelwa njengomgangatho. Izixhobo ezizezinye zingabonelelwa ukuba zichaziwe umz. i-polyethylene enoxinano oluphakathi (MDPE).
Idatha yombane:
Ubushushu obuphezulu bomqhubi osebenzayo: 90°C
Ubushushu obuphezulu bokusebenza kwesikrini: 80°C
Ubushushu obuphezulu bomqhubi ngexesha le-SC: 250°C
Iimeko zoVavanyo lwangoku:
Ubushushu bomhlaba 15°C
Ubushushu obuphakathi (umoya) 25°C
Ubunzulu bokungcwaba 0.8m
Ukumelana nobushushu bomhlaba yi-1.2°C m/W
