Thumela i-imeyileIintambo zombane ze-XLPE ezifakwe i-insulation ye-19/33kV zifanelekile kwiinethiwekhi zamandla ezifana nezitishi zamandla. Zokufakelwa kwiipayipi, phantsi komhlaba nangaphandle. Zingasetyenziswa nakwiindawo ezizinzileyo kwiinethiwekhi zokusasaza, kwiindawo zoshishino, nakwizikhululo zamandla. Nceda uqaphele: I-sheath yangaphandle ebomvu inokuba sengozini yokunyamalala xa ivezwe kwimitha ye-UV. Iintambo ze-voltage ephakathi zenziwe kusetyenziswa inkqubo ye-monosil. Sinikezela ngezityalo ezikhethekileyo kakhulu, izibonelelo zophando zanamhlanje kunye neenkqubo zokulawula umgangatho ezifunekayo ekwenzeni iintambo ze-PVC ezifakwe i-insulation ukuze zisetyenziswe ukuya kuthi ga kwi-6KV kunye neentambo ze-XLPE/EPR ezifakwe i-insulation ukuze zisetyenziswe kwii-voltage ukuya kuthi ga kwi-35 KV. Zonke ezi zinto zigcinwa kwiimeko ezilawulwa bucoceko kuyo yonke inkqubo yemveliso ukuqinisekisa ukulingana okupheleleyo kwezinto zokufakelwa ezigqityiweyo.
