Hōʻuluʻulu manaʻo
ʻO kā mākou huahana hou, NVS1-24 series i loko o ka hale kiʻekiʻe-voltage vacuum circuit breakers i hoʻohana ʻia no nā switchgears i ka ʻōnaehana mana 24kV, ma ke ʻano he mana a me ka pale o nā lako uila i nā ʻoihana ʻoihana a me nā ʻoihana mining, nā mea kanu mana a me nā substations. Ma muli o nā pōmaikaʻi kūikawā o ka mea hoʻoheheʻe kaapuni māmā, kūpono loa ia no nā hana maʻamau e koi ana i ka manawa hana i helu ʻia, a i ʻole nā wahi kahi i haki ʻia ai ka manawa pōkole. Hoʻohana ka mea haʻihaʻi kaapuni i ka hoʻolālā hoʻohui ʻia o ka mīkini hana a me ke kino breaker circuit. ʻO nā mea ʻelua he hale i mua a i hope, me ka hana pili pono. Hiki ke hoʻohana ʻia ka mea hoʻokele kaapuni ma ke ʻano he ʻāpana hoʻonohonoho paʻa. Hiki ke hoʻolako pū ʻia me kahi kaʻa chassis i loko o kahi hui kaʻa lima.
