Whakaahuatanga Poto:

Ko te Zw7-40.5 raupapa o waho he pūwhakawhiti hiko korehau teitei AC 50Hz e toru-wāhanga. He taputapu whakawhiti hiko korehau teitei o waho me te ngaohiko whakatauranga o te 40.5Kv. He pūnaha whakahaere puna, he pūnaha whakahaere hikohiko rānei, ka taea te whakahaere mamao i te wehenga me te kati hiko, ā, ka taea hoki te penapena ā-ringa i te hiko, te wehenga ā-ringa me te kati. Ka tutuki te mahi hoahoa i ngā whakaritenga o te paerewa ā-motu GB1984 "pūwhakawhiti hiko korehau teitei AC", ā, ka tutuki i ngā whakaritenga o te paerewa IEC62271:100 "pūwhakawhiti hiko korehau AC" International Electrotechnical Commission. Ko te pūwhakawhiti hiko korehau ZW7-40.5 te nuinga o te wā e whakamahia ana mō te whakahaere me te tiaki i te pūnaha tuku me te whakawhiti hiko 35KV o waho, ā, he pai hoki mō te mahi noa me te tiaki i te ara iahiko poto o ngā whatunga tohatoha hiko o te tāone me te taiwhenua me ngā umanga ahumahi me te keri. Ko te hanganga whānui o te hua he momo pou porcelain; Ko te pounamu porcelain o runga he rūma tinei pewa korehau, ā, ko te pounamu porcelain o raro he pounamu porcelain pou. He pai mō te mahi auau. He pai ngā āhuatanga o te hiri, te ārai i te koroheketanga, te ātete ki te pēhanga teitei, te kore mura, te kore pahū, te roa o te ora ratonga, te ngāwari o te tāutanga me te tiaki.
