Hoʻohana nui ʻia ʻo GCK low-voltage withdrawable switchgear i nā mea kanu mana, metallurgical rolling, petrochemical, light industry and textile, ports, buildings, hotels a me nā wahi ʻē aʻe e like me AC ʻekolu-phase ʻehā-wire a ʻelima-wire pūnaewele, voltage 380V, 660V, pinepine 50Hz, helu ʻia Hoʻohana ʻia ia no ka hāʻawi ʻana i ka mana a me ka hoʻokele kikowaena kaʻa i nā ʻōnaehana lako mana me nā au o 5000A a ma lalo.
ʻO GCK kahi mea hoʻololi haʻahaʻa haʻahaʻa haʻahaʻa kiʻekiʻe i hōʻuluʻulu ʻia a ʻākoakoa ʻia, a ua hoʻolālā ʻia e hoʻokō i kēia mau kūlana:
ʻO ke kūlana aupuni GB7251.1-2005 "Low-voltage switchgear"
International standard IEC60439.1-1992 "Low-voltage switchgear and control equipment"
Ke Ana Hoʻohālike
