Hoʻokumu ʻia ʻo GCS haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa hoʻihoʻi ʻia (ma hope o ka mea i kapa ʻia ʻo ka mea hana) e ka hui hoʻolālā hui o ka Ministry of Machinery mua a me ka Ministry of Electric Power e like me nā koi o ka ʻoihana mana kūpono, ka hapa nui o nā mea hoʻohana mana a nā ʻāpana hoʻolālā.Ua like ia me nā kūlana aupuni, loaʻa nā hōʻailona hoʻokō ʻenehana kiʻekiʻe, a hiki iā A haʻahaʻa-voltage withdrawable switchgear e hoʻokō i nā pono hoʻomohala o ka mākeke mana a hiki ke hoʻokūkū me nā huahana i lawe ʻia mai.Ua hala ka mea i ka loiloi i mālama pū ʻia e nā keʻena ʻelua ma Shanghai i Iulai 1996, a ua waiwai a hōʻoia ʻia e ka ʻoihana hana a me ka ʻoihana hoʻohana mana.
Ua kūpono ka mea hana no nā ʻōnaehana hoʻoili mana i nā mea kanu mana, ka ʻaila, kemika, metallurgy, textile, nā hale kiʻekiʻe a me nā ʻoihana ʻē aʻe.I nā mea kanu mana nui, nā ʻōnaehana petrochemical a me nā wahi ʻē aʻe me kahi kiʻekiʻe o ka automation, nā wahi e koi ai i ka interface me ke kamepiula e hoʻohana ʻia e like me ʻekolu-phase AC 50 (60) Hz, helu ʻia ka volta hana 380V, helu ʻia i kēia manawa 4000A a ma lalo i loko. ka hāʻawi mana a me nā ʻōnaehana hoʻolako mana no ka hāʻawi ʻana i ka mana a me ka neʻe ʻana o ka kaʻa.
