Izixhobo zekhebula zokunciphisa ubushushu ze-20kV

Inkcazo emfutshane:

Iimveliso zothotho lwezixhobo zekhebula ezincitshiswa bubushushu ze-20kV, zilungele i-12/20kV, i-18/24kV enesiseko esinye, ezintathu-

iintambo zombane ze-polyethylene ezingundoqo kunye neentambo zombane ze-polyethylene ezidityanisiweyo, ezingangeni manzi ezibekwe, ulawulo loxinzelelo, ukhuselo,

ubushushu obukwindawo enye. Ngenxa yeempawu ezilungileyo zombane nezoomatshini, ingasetyenziswa kwiindawo ezahlukeneyo ezinobungozi zokusingqongileyo

iimeko ixesha elide. Inezibonelelo zobunzima obulula kunye nokulula ukuyifaka. Isetyenziswa kakhulu kumbane

umbane, ipetroliyam, iikhemikhali, isinyithi, uloliwe, izibuko kunye nolwakhiwo kunye neminye imimandla
