Tuhinga o mua：Hang Zhou, Haina
Whakaahuatanga Whanui
Ko te ZN23-40.5 kohinga hiko hiko hiko teitei kei roto i te 40.5KV e toru nga waahanga AC 50Hz e pai ana mo te whakahaere me te tiaki i te punaha tohatoha o nga umanga umanga, he waahanga motuhake mo te umanga whakarewa i te waa me mahi tonu te oumu hiko hiko.
Ka ea tenei kaakahu i nga whakaritenga a GB1984-89 "AC High voltage circuit breakers" ka taea te pana ki te GBC-35, te poraka hiko JYN1-35 teitei, mena ka tangohia nga pereki o te kaiwhakawhati, ka taea te whakakii takitahi.
