Thumela i-imeyileI-19/33kV XLPE-insulated medium-voltage power cables zilungele uthungelwano lwamandla olufana nezikhululo zamandla. Ukufakwa kwimibhobho, phantsi komhlaba nangaphandle. Isenokusetyenziselwa ufakelo olusisigxina phakathi kothungelwano losasazo, indawo yoshishino, kunye nezikhululo zombane. Nceda uqaphele: I-sheath yangaphandle ebomvu inokufiphala xa ibekwe kwimitha ye-UV. Iintambo zombane ophakathi zenziwe kusetyenziswa inkqubo ye-monosil. Sibonelela ngesityalo esikhethekileyo, amaziko ophando akwinqanaba eliphezulu kunye neenkqubo zokulawula umgangatho ezicokisekileyo ezifunekayo ukuze kwenziwe iintambo ze-PVC ezigqunyiweyo ukuze zisetyenziswe ukuya kuthi ga kwi-6KV kunye ne-XLPE/EPR iintambo ezigqunyiweyo ukuze zisetyenziswe kumbane ukuya kuthi ga kwi-35 KV. Izinto eziphathekayo zonke zigcinwe kwiimeko ezilawulwa ngokucoceka kuyo yonke inkqubo yokuvelisa ukwenzela ukuba kuqinisekiswe i-homogeneity epheleleyo yezinto ezigqityiweyo zokugquma.
