Thumela i-imeyileIintambo ze-LSZH MV zikwabandakanya i-PVC eyodwa-core AWA iintambo ezixhobileyo kunye ne-XLPE ezininzi zeentambo ze-SWA ezixhobileyo.
Olu luyilo luqhele ukusetyenziswa kwiintambo zamandla ezincedisayo kwiigridi zamandla kunye neendawo ezahlukeneyo.Isikrweqe esibandakanyiweyo sithetha ukuba intambo inokungcwatywa ngokuthe ngqo emhlabeni ukuthintela ukothuka ngengozi kunye nomonakalo.
Iintambo ze-LSZH zahlukile kwiintambo ze-PVC kunye neentambo ezenziwe kwezinye iikhompawundi.
Xa intambo ibamba umlilo, inokuvelisa umsi omninzi omnyama oshinyeneyo kunye neegesi ezinetyhefu.Nangona kunjalo, ngenxa yokuba intambo ye-LSZH yenziwe ngesixhobo se-thermoplastic, ivelisa kuphela umsi omncinci kunye neegesi ezinetyhefu, kwaye ayinazo iigesi ze-asidi.
Kwenza kube lula ukuba abantu babaleke emlilweni okanye kwindawo eyingozi.Ke ngoko, zihlala zifakwa ngaphakathi, njengakwindawo zikawonke-wonke, kwezinye iindawo ezinobungozi, okanye iindawo ezingenamoya omdaka.

Iintambo zeVolgeji eziyilwe ngokweSiko:
Ukusebenza kakuhle kunye nokuphila ixesha elide, yonke intambo ye-MV kufuneka ilungiselelwe ukufakelo kodwa kukho amaxesha apho kufuneka intambo ye-bespoke ngokwenene.Iingcali zethu zentambo ye-MV zinokusebenza nawe ukuyila isisombululo esihambelana neemfuno zakho.Ngokuqhelekileyo, uhlengahlengiso luchaphazela ubungakanani bendawo yesikrini sentsimbi, esinokuhlengahlengiswa ukuze sitshintshe umthamo wesekethe emfutshane kunye nezibonelelo zomhlaba.
Kuzo zonke iimeko, idatha yobugcisa inikezelwa ukubonisa ukufaneleka kunye neenkcukacha eziphuculweyo zokwenziwa.Zonke izisombululo ezilungiselelweyo zixhomekeke kuvavanyo oluphuculweyo kwiZiko lokuVavanya iCable yeMV.
