Wehewehe Pōkole:

ʻO ZW8- 12 Series VCB, he lako hoʻololi uila kiʻekiʻe waho me ka uila i helu ʻia he 12KV, 3-phase AC 50HZ. ʻO ia ke kumu nui hoʻohana ʻia e uhaʻi i ke au ukana, ke au overload a me ke au pōkole no ka pūnaewele mana kuaʻāina, ka pūnaewele mana kūlanakauhale a me ka mana liʻiliʻi ʻōnaehana. He 3-phase ka hale i loko o kahi pahu like. Aia ka mea hoʻopau hakahaka 3-phase i loko o ka pahu metala, i lawe ʻia i ka mea insulated ʻO SMC ma ke ʻano he insulation pae i ka pae a me ka insulation honua. Loaʻa iā ia ka hana hilinaʻi, kiʻekiʻe loa ka pae insulating.

ʻO ZW8-12G ka hui pū ʻana o ZW8-12 a me ke kuapo hoʻokaʻawale, i kapa ʻia ʻo ka mea haki kaapuni hui pū ʻana, hiki ke hoʻohana ʻia e like me ka hoʻokaʻawale i nā kuapo.

ʻO ke actuator no kēia huahana he ʻano CT23, ʻano hoʻouka puna, hiki ke ʻano uila a i ʻole ke ʻano manual.
