Iintambo zeAluminiyam ezingaphezulu zisetyenziselwa ngaphandle kwiindawo zokuhambisa.Bathwala amandla ukusuka kwimigca eluncedo ukuya kwizakhiwo ngokusebenzisa imozulu.Ngokusekelwe kulo msebenzi othile, iintambo zikwachazwa njengeentambo zokuwisa inkonzo.Iintambo zeAluminiyam ezingaphezulu zibandakanya i-duplex, i-triplex, kunye neentlobo ze-quadruplex.Iintambo ze-Duplex zisetyenziswa kwiintambo zombane zesigaba esinye, ngelixa iintambo ezine-quadruplex zisetyenziswa kwiintambo zombane ezikwisigaba esithathu.Iintambo ze-Triplex zisetyenziselwa kuphela ukuthwala umbane ukusuka kwiintambo zoncedo ukuya kubathengi.
Umqhubi weAluminiyamiintambo zenziwe nge-aluminium ethambileyo ye-1350-H19 series.Zifakwe kwi-polyethylene ye-thermoplastic extruded okanye i-polyethylene edibeneyo enqamlezileyo ukukhusela kwiimeko eziyingxaki zangaphandle.Iintambo zenzelwe ubushushu bokusebenza ukuya kuthi ga kwi-75 degrees kunye ne-voltage rating ye-600 volts.
