AS / NZS isanzwe 19-33kV-XLPE Umugozi wa MV Umuyoboro
Gukwirakwiza amashanyarazi cyangwa imiyoboro yohereza imiyoboro isanzwe ikoreshwa nkibikoresho byambere byubucuruzi, Inganda n’imijyi ituye.Bikwiranye na sisitemu yo murwego rwohejuru igera kuri 10kA / 1sec.Ikosa rihanitse ryubu ryubatswe riraboneka kubisabwa.
Ingano ya MV:
Imiyoboro yacu ya 10kV, 11kV, 20kV, 22kV, 30kV na 33kV iraboneka murwego rukurikira rwambukiranya ibice (bitewe nuyobora umuringa / Aluminium) kuva 35mm2 kugeza 1000mm2.
Ingano nini iraboneka iyo ubisabwe.

IEC / BS Bisanzwe 19-33kV-XLPE Yashizwemo MV Hagati yumuriro w'amashanyarazi
Imiyoboro ya voltage yo hagati ikorwa hifashishijwe inzira ya monosil.Dutanga uruganda rwihariye cyane, ibikoresho byubushakashatsi bugezweho hamwe nuburyo bunoze bwo kugenzura ubuziranenge busabwa mu gukora insinga za PVC zikoreshwa mu gukoresha insinga zigera kuri 6KV na XLPE / EPR zikoreshwa mu gukoresha amashanyarazi agera kuri 35 KV .Ibikoresho byose bibikwa muburyo bugenzurwa nisuku mugihe cyose cyakozwe kugirango habeho uburinganire bwuzuye bwibikoresho byuzuye.

IEC BS Bisanzwe 12-20kV-XLPE Yashizwemo PVC yometse kuri MV Umuyoboro
Birakwiriye imiyoboro yingufu nka sitasiyo yamashanyarazi.Kugirango ushyire mumiyoboro, munsi yubutaka no hanze.
Hariho itandukaniro rinini mubwubatsi, ibipimo nibikoresho byakoreshejwe - kwerekana umugozi wa MV ukwiye kumushinga ni ikibazo cyo guhuza ibisabwa, imikorere isabwa, nibibazo by’ibidukikije, hanyuma ukareba niba insinga, inganda, no kubahiriza amabwiriza.Hamwe na komisiyo mpuzamahanga y’amashanyarazi (IEC) isobanura insinga za Medium Voltage zifite umuvuduko uri hejuru ya 1kV kugeza kuri 100kV ibyo bikaba ari nini ya voltage yagombye gusuzuma.Birasanzwe gutekereza nkuko tubikora ukurikije 3.3kV kugeza 35kV, mbere yuko iba voltage nyinshi.Turashobora gushigikira insinga zidasanzwe muri voltage zose.
