Ohereza imeriGukwirakwiza 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.
Urwego rw'ubushyuhe:
Ubushyuhe ntarengwa bwo kwishyiriraho: 0 ° C.
Ubushyuhe ntarengwa bwo gukora: + 90 ° C.
Ubushyuhe buke bwo gukora: -25 ° C.
Iradiyo ntarengwa
Intsinga zashyizweho: 12D (PVC gusa) 15D (HDPE)
Mugihe cyo kwishyiriraho: 18D (PVC gusa) 25D (HDPE)
Kurwanya imiti igaragara: Impanuka
Ingaruka ya mashini: Umucyo (PVC gusa) Biremereye (HDPE)
Amazi ahura: XLPE - Sasa EPR - Kwibiza / Gukwirakwiza by'agateganyo
Imirasire y'izuba hamwe nikirere: Birakwiriye guhura neza.
Ubwubatsi:
Yakozwe nubwoko bwapimwe AS / NZS 1429.1, IEC: 60502-2 nibindi bipimo bikurikizwa
Imiterere - 1 yibanze, 3 yibanze
Umuyobora - Cu cyangwa AL, Uruziga ruzengurutse, ruzengurutse uruziga, Urwego rwa Milliken
Gukingira - XLPE cyangwa TR-XLPE
Mugaragaza ibyuma cyangwa icyuma - Mugozi wumuringa (CWS), Mugaragaza Umuringa (CTS)
Intwaro - Aluminium Wire Armored (AWA), Icyuma Cyuma Cyuma (SWA), polyethylene (HDPE) hanze - ubundi
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.
