Iintambo ngokohlobo

Ikhebula yombane ophakathi

Iintambo zamandla ombane aphakathi (iintambo ze-MV), ngokwesiqhelo eziyilelwe amandla ombane ukusuka kwi-1 kV ukuya kwi-35 kV, zibalulekile kugqithiso olufanelekileyo nokusasazwa kwamandla ombane kwiindawo ezahlukeneyo. Ezi ntambo zenzelwe ukuhambisa ukusebenza okuthembekileyo kufakelo lwangaphakathi nangaphandle, ukuphatha amandla ombane aphezulu kuneentambo zombane ophantsi kwaye ngaloo ndlela zivumela ukuhanjiswa kwamandla kumgama omde kunye nelahleko encinci.

Sinikezela ngoluhlu olubanzi lweentambo ze-Medium Voltage ezine-insulation ephezulu yombane, ukuqina, ukukhusela, ukumelana nomlilo, kunye nokunyamezela ubushushu. Ezi mpawu zenza iintambo zethu zeMV zilungele usetyenziso oluhlukeneyo. Zingamacandelo abalulekileyo kuthungelwano lokuhambisa amandla, ukuhambisa umbane ukusuka kwizitishi ezincinci ukuya kwimizi-mveliso, zorhwebo, kunye neendawo zokuhlala. Kufakelo lwemizi-mveliso, olufana neefektri kunye neendawo zokucoca, iintambo zombane ophakathi zibalulekile ekugcineni amandla athembekileyo ekusebenzeni. Zikwabalulekile kwizityalo zamandla ahlaziyekayo, ziququzelela ukuhanjiswa kwamandla avela kwiifama zomoya kunye nelanga ukuya kwigridi. Ukongeza, ezi ntambo zisetyenziswa kufakelo olungaphantsi komhlaba kunye nenkwili, kunye neziseko zophuhliso zoluntu ezifana nezikhululo zeenqwelomoya kunye noololiwe, apho umbane ozinzileyo nosebenzayo ubalulekile.
