Thumela i-imeyileIintambo zombane ze-XLPE ezifakwe i-insulated medium-voltage (MV) eziyi-8.7/15kV zifanelekile kwiinethiwekhi zamandla ezifana nezikhululo zamandla. Zifanelekile kwiinethiwekhi zamandla ezifana nezikhululo zamandla. Zifakelwe kwiipayipi, phantsi komhlaba nangaphandle. Zingasetyenziswa nakwindlela yokuhambisa nokusasaza ngaphakathi kwiigridi zamandla, kwiindawo zoshishino, nakwiiprojekthi zeziseko zophuhliso. Nceda uqaphele: I-sheath yangaphandle ebomvu inokuba sengozini yokunyamalala xa ivezwe kwimitha ye-UV.
