Thumela I-imeyiliIzintambo ze-LSZH MV zibandakanya izintambo ze-armored ze-PVC ze-AWA kanye nezintambo ze-armored ze-SWA ze-XLPE eziningi.
Lo mklamo uvame ukusetshenziselwa izintambo zamandla asizayo kumagridi kagesi nasezindaweni ezihlukahlukene.Izikhali ezifakiwe zisho ukuthi ikhebula lingangcwatshwa ngqo phansi ukuze kuvinjelwe ukushaqeka nokulimala ngengozi.
Izintambo ze-LSZH zihlukile kuzintambo ze-PVC nezintambo ezenziwe ngezinye izinhlanganisela.
Lapho intambo ibamba umlilo, ingakhipha intuthu emnyama eminyene kanye namagesi anobuthi.Nokho, ngenxa yokuthi ikhebula le-LSZH lenziwe ngezinto ezishisayo, likhiqiza intuthu encane namagesi anobuthi, futhi alinawo amagesi ane-asidi.
Kwenza kube lula ukuthi abantu babaleke emlilweni noma endaweni eyingozi.Ngakho-ke, zivame ukufakwa endlini, njengasezindaweni zomphakathi, kwezinye izindawo eziyingozi, noma izindawo ezingenawo umoya ohlanzekile.

I-5V-90 polyvinyl chloride emnyama (PVC) - ejwayelekile
Owolintshi 5V-90 PVC yangaphakathi kanye nokuminyana okuphezulu okumnyama
Intuthu ephansi zero halogen (LSOH) - okunye
Izintambo eziklanywe ngokwezifiso ze-Medium Voltage:
Ukuze usebenze kahle nokuphila isikhathi eside, yonke ikhebula ye-MV kufanele ifanelane nokufakwa kodwa kunezikhathi lapho kudingeka khona ikhebula le-bespoke ngempela.Ochwepheshe bethu bekhebula le-MV bangasebenza nawe ukuze baklame isixazululo esihambisana nezidingo zakho.Ngokuvamile, ukwenza ngokwezifiso kuthinta usayizi wendawo wesikrini se-metallic, esingalungiswa ukuze kushintshwe umthamo wesekethe emfushane kanye nokuhlinzekwa komhlaba.
Kuzo zonke izimo, idatha yobuchwepheshe inikezwa ukukhombisa ukufaneleka kanye nencazelo ecijile ukuze yenziwe.Zonke izixazululo ezenziwe ngokwezifiso zingaphansi kokuhlolwa okuthuthukisiwe esikhungweni sethu sokuhlola ikhebula le-MV.
Ikhebula lamandla angu-12.7/22kV
