Thumela I-imeyiliIzintambo zikagesi ezingu-8.7/15kV XLPE-insulated medium-voltage (MV) zilungele amanethiwekhi kagesi njengeziteshi zikagesi. Ifanele amanethiwekhi wamandla njengeziteshi zikagesi. Ukufakwa emiseleni, ngaphansi nangaphandle. Ingase futhi isetshenziswe ekudluliselweni nasekusabalaliseni ngaphakathi kwamagridi kagesi, indawo yezimboni, namaphrojekthi wengqalasizinda. Sicela uqaphele: Igobolondo langaphandle elibomvu lingaba lula ukufiphala lapho lichayeke emisebeni ye-UV.
