Thumela I-imeyili6/10kV XLPE-insulated medium-voltage power cables afaneleka kunethiwekhi yamandla njengeziteshi zikagesi. Angase afakwe emiseleni, ngaphansi komhlaba, nangaphandle, kanye nasezindaweni ezingaphansi kwamandla angaphandle ayimishini. I-conductor isebenzisa ukufakwa kwe-XLPE, enikeza ukumelana nokushisa okuhle kakhulu nokumelana nokugqwala kwamakhemikhali, ngaleyo ndlela ivumele ukusetshenziswa ezimbonini zamakhemikhali nasezindaweni ezingcolile. I-aluminium wire armor (AWA) yezintambo eziwumgogodla owodwa kanye nensimbi yensimbi yesikhali (i-SWA) yamakhebuli amaningi ahlinzeka ngokuvikelwa komshini okuqinile okwenza lezi zintambo ezingu-11kV zifanelekele ukungcwatshwa ngokuqondile emhlabathini. Lawa makhebula kagesi e-armored MV mains avame ukunikezwa amakhondaktha ethusi kodwa ayatholakala namakhondatha e-aluminium uma ecelwa ngezinga elifanayo. Amakhondaktha ethusi aminyene (Ikilasi 2) kuyilapho amakhondatha e-aluminium ethobelana nendinganiso esebenzisa kokubili ukwakhiwa okuminyene nokuqinile (Ikilasi 1).

Ukwakha :
1.Umqhubi
Ikhondatha yethusi eyindilinga eyindilinga ehambisana ne-BS6360 Class 2.
Isikrini Somqhubi
Inhlanganisela ye-semi-conducting enwetshiwe eboshelwe ku-insulation futhi isetshenziswe ekusebenzeni okufanayo nokufakwa.
2.I-Insulation
I-ployethylene (XLPE) e-extruded cross-linked ilungele ukusebenza ezingeni lokushisa likakhondatha elingu-90°C.
3.Isikrini Sokugquma
Inhlanganisela ye-semi-conducting enwetshiwe isetshenziswa ekusebenzeni okufanayo nokufakwa. Izikrini ezikhumukayo ezibandayo zinikezwa njengezikrini ezijwayelekile kodwa eziboshwe ngokugcwele zinganikezwa uma zicacisiwe.
4.Metallic Screen
Amateyipu ethusi asetshenziswe agqagqene ukuze anikeze indlela yamanje yephutha lomhlaba.
5.Ukubeka
Ama-cores amathathu abekwe nge-polypropylene string fillers ukuze akhe ikhebula eliyindilinga elihlangene, futhi liboshwe ngetheyiphu.
6.Tape Binder
7.Umgodla
I-polyvinyl chloride emnyama enwetshiwe (PVC) noma inhlanganisela ye-Low Smoke Zero Halogen (LSOH) inikezwa njengokujwayelekile. Ezinye izinto zinganikezwa uma zibaluliwe.
8.Izikhali
Isendlalelo esisodwa sezintambo zensimbi eziyindilinga.
9.Oversheath
I-polyvinyl chloride emnyama enwetshiwe (PVC) noma inhlanganisela ye-Low Smoke Zero Halogen (LSOH) inikezwa njengokujwayelekile. Ezinye izinto zinganikezwa uma kucacisiwe isb. i-medium density polyethylene (MDPE).
