Thumela I-imeyili19/33kV XLPE-insulated medium-voltage power cables afaneleka kunethiwekhi yamandla njengeziteshi zikagesi. Ukufakwa emiseleni, ngaphansi nangaphandle. Ingase futhi isetshenziselwe ukufakwa okugxilile ngaphakathi kwamanethiwekhi okusabalalisa, izakhiwo zezimboni, neziteshi zikagesi. Sicela uqaphele: Igobolondo langaphandle elibomvu lingaba lula ukufiphala lapho lichayeke emisebeni ye-UV. Izintambo zikagesi ezimaphakathi zenziwa kusetshenziswa inqubo ye-monosil. Sihlinzeka ngemishini ekhetheke kakhulu, izikhungo zocwaningo ezisezingeni eliphezulu kanye nezinqubo zokulawula ikhwalithi ezicophelelayo ezidingekayo ukuze kwenziwe amakhebuli avaleleke e-PVC ukuze asetshenziswe kufika ku-6KV kanye nezintambo ezivale izintambo ze-XLPE/EPR ukuze zisetshenziswe kuma-voltage afika ku-35 KV. Izinto ezisetshenziswayo zonke zigcinwa ezimeni ezilawulwa ukuhlanzeka kuyo yonke inqubo yokukhiqiza ukuze kuqinisekiswe ukufana okuphelele kwezinto zokufakelwa eziqediwe.
