Thumela i-imeyiliIzintambo zikagesi ze-XLPE ezifakwe i-XLPE ezi-6/10kV zifanelekela amanethiwekhi kagesi njengeziteshi zikagesi. Zingafakwa emihubheni, ngaphansi komhlaba, nangaphandle, kanye nasezindaweni ezingaphansi kwamandla angaphandle omshini. Umshini usebenzisa i-XLPE insulation, enikeza ukumelana okuhle kakhulu kokushisa kanye nokumelana nokugqwala kwamakhemikhali, ngaleyo ndlela evumela ukusetshenziswa ezimbonini zamakhemikhali nasezindaweni ezingcolile. I-aluminium wire armour (AWA) yezintambo eziyinhloko eyodwa kanye nensimbi wire armour (SWA) yezintambo eziningi eziyinhloko inikeza ukuvikelwa okuqinile komshini okwenza lezi zintambo ze-11kV zifanele ukungcwatshwa ngqo emhlabathini. Lezi zintambo zikagesi ze-MV mains ezivikelwe zivame ukunikezwa ngama-conductor ethusi kodwa ziyatholakala futhi nama-conductor e-aluminium uma ziceliwe ngokwezinga elifanayo. Ama-conductor ethusi avalelekile (Isigaba 2) kanti ama-conductor e-aluminium ahambisana nezinga esebenzisa kokubili izakhiwo ezivalelekile neziqinile (Isigaba 1).

Ukwakhiwa:
1. Umqhubi
Umqhubi wethusi oqinile oyisiyingi ohambisana ne-BS6360 Class 2.
Isikrini Somqhubi
Inhlanganisela ekhipha i-semi-conducting ehlanganisiwe exhunywe ku-insulation futhi isetshenziswa ekusebenzeni okufanayo no-insulation.
2. Ukuvikela
I-ployethylene exhumene ne-cross-linked (XLPE) enwetshiwe efanelekile ukusebenza ekushiseni komqhubi okungu-90°C.
3. Isikrini Sokuvala Ukushisa
Inhlanganisela ye-semi-conducting ekhishwe ngaphandle esetshenziswa ekusebenzeni okufanayo nokufakwa kwe-insulation. Izikrini ezibandayo ezihlubulayo zinikezwa njengezikrini ezijwayelekile kodwa eziboshwe ngokuphelele zinganikezwa uma kuchaziwe.
4. Isikrini sensimbi
Amateyipu ethusi afakwe ahambisana ukuze anikeze indlela yamanje yephutha lomhlaba.
5. Ukubeka phansi
Ama-core amathathu abekwe ngezithasiselo zezintambo ze-polypropylene ukuze akhe ikhebula eliyindilinga elincane, bese eboshwa ngetheyiphu.
6. I-Tape Binder
7. Umgodla
I-polyvinyl chloride (PVC) emnyama ekhishwe noma i-Low Smoke Zero Halogen (LSOH) ehlanganisiwe inikezwa njengejwayelekile. Izinto ezihlukile zinganikezwa uma zichaziwe.
8. Ukuvikela ngezikhali
Isendlalelo esisodwa sezintambo zensimbi eziyindilinga ezifakwe i-galvanized.
9. I-Oversheath
I-polyvinyl chloride emnyama ekhishwe (PVC) noma i-Low Smoke Zero Halogen (LSOH) compound enikeziwe njengejwayelekile. Izinto ezingasetshenziswa zinganikezwa uma kucacisiwe isib. i-polyethylene ephakathi nendawo (MDPE).
Imininingwane kagesi:
