I-conductivity ephezulu ihlanganiswe, i-Conductor ye-Class 1 Solid, i-Class 2 ye-stranded copper noma i-aluminium conductors, efakwe insulation futhi efakwe umbala nge-XLPE.
Ukufakwa okugxilile kwamasistimu okudlulisela nokusabalalisa, amahubhu namapayipi nezinye izikhathi.
Ukuze isimo akufanele sithwale amandla angaphandle mechanical.
