12 17.5 24kV Indoor Vacuum Circuit Breakers, GPVN-E Series

Inkcazelo emfutshane:

I-GPVN-12kV/17.5Kv/24kV Imodeli yangaphakathi ye-AC i-high voltage vacuum i-breaker circuit luhlobo lwe-holistic kwaye lutywinwe ngokupheleleyo i-High Voltage switchgear, inomlinganiselo ohlangeneyo kunye nomthamo omncinci.I-VCB isebenza kwinkqubo yamandla ombane olinganisiweyo 7.2 ~ 24kV, isigaba sesithathu kunye ne-AC 50 / 60Hz.Isebenza kwiimeko kunye nokusebenza rhoqo, ukusebenza ukukhusela nokulawula umgca kunye nezixhobo zombane.Imveliso ihambelana ne-IEC62271-100, GB1984, JB3855 kunye ne-DL1403 kwaye iphumelele uvavanyo lohlobo.
