ʻO YB-12 / 0.4 pahu-type substation (kiʻekiʻe a haʻahaʻa voltage pre-installed substation) he kiʻekiʻe-voltage switchgear, distribution transformer a me ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, e like me kekahi ʻano wili i hoʻonohonoho ʻia i loko o kekahi o ka hale hana prefabricated i loko a nā lako hoʻolaha paʻa waho, ʻo ia hoʻi, transformer step-down, haʻahaʻa-voltage distribution a me nā hana ʻē aʻe i hui pū ʻia. Hoʻokomo ʻia i loko o kahi moisture-proof, rust-proof, dust-proof, rat-proof, fireproof, anti-theft, heat insulation, hoʻopaʻa piha ʻia, movable steel structure box, ʻoi aku ka maikaʻi no ke kūkulu ʻana i ke kūlanakauhale a me ka hoʻololi ʻana, he substation hou ma hope. ka piʻi ʻana o nā hale kīwila. ʻO ka pahu-type substation he kūpono ia no nā mines, nā ʻoihana ʻoihana, nā māla aila a me ke kinoea a me nā keʻena makani makani, hoʻololi ia i ka lumi hoʻolaha kīwila mua, ke kahua mana hoʻolaha, a lilo i pūʻulu piha hou o ka transformer a me nā lako hoʻoili.
ʻO YB series preassembled substation i nā hiʻohiʻona o ka hoʻonohonoho piha ikaika, ka liʻiliʻi liʻiliʻi, ka hale paʻa, ka hana palekana a hilinaʻi, mālama maʻalahi, a me ka neʻe ʻana, a me nā mea ʻē aʻe. ʻO 1/10 wale nō ~ 1/5 o nā substation maʻamau, e hōʻemi nui ana i ka hana hoʻolālā a me ka nui o ke kūkulu ʻana, a hoʻemi i ke kumukūʻai kūkulu.
