ʻO Zw7-40.5 moʻo waho kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe vacuum kaapuni breaker he ekolu-phase AC 50Hz. ʻO waho o ke kiʻekiʻe-voltage switchgear me ka helu helu o 40.5Kv. Hoʻolako ʻia me ka mīkini hana puna a i ʻole ka mīkini hana electromagnetic, hiki iā ia ke hoʻomalu mamao i ka hoʻokaʻawale ʻana a me ka pani ʻana, a hiki ke mālama pono ʻia i ka ikehu, hoʻokaʻawale lima a pani. Hoʻokō ka hana hoʻolālā i nā koi o GB1984 "AC high voltage circuit breaker" kūlana aupuni, a hoʻokō i nā koi o IEC62271: 100 "High voltage AC circuit breaker" International Electrotechnical Commission standard. Hoʻohana nui ʻia ʻo ZW7-40.5 vacuum circuit breaker no ka mālama ʻana a me ka pale ʻana o ka mana waho 35KV a me ka ʻōnaehana hoʻololi, a ua kūpono hoʻi no ka hana maʻamau a me ka pale kaapuni pōkole o nā ʻoihana hoʻolaha mana kūloko a me nā ʻoihana a me nā ʻoihana mining. ʻO ke ʻano holoʻokoʻa o ka huahana he ʻano kia porcelain; Hoʻolako ʻia ka ʻōmole porcelain luna me kahi keʻena hoʻopau arc, a ʻo ka ʻōmole porcelain haʻahaʻa he ʻōmole porcelain kia. He kūpono no ka hana pinepine. Loaʻa iā ia nā hiʻohiʻona o ka sila maikaʻi, anti-aging, ke kūpaʻa kiʻekiʻe, ʻaʻohe puhi, ʻaʻohe pahū, ola lōʻihi, hoʻonohonoho maʻalahi a mālama.
