ʻO ka ʻoihana kaʻa kuʻuna o Kina ka ʻoihana kaʻa. Ma hope o nā makahiki o ka noiʻi a me ka hana hou, ua hoʻomohala ʻo SIMO Motor i kahi hui kaʻa kiʻekiʻe ma Kina. Hoʻohui ʻo SIMO Motor i ka hoʻolālā kaʻa, hana a me ke kūʻai aku ma ke ʻano o ka maikaʻi. ʻO SIMO Electric Company, ua lanakila nā huahana SIMO Electric i ke kūlana maikaʻi a lawe ʻia aku i nā ʻāina a puni ka honua. ʻO Xima Motor i kēia manawa he kaʻa kiʻekiʻe ma waena o nā huahana kaʻa o Kina.
ʻO ka mīkini kiʻekiʻe-voltage he motika e holo ana i ka volta kiʻekiʻe a hoʻohana mau ʻia i nā noi ʻoihana nui a me nā ʻōnaehana mana. ʻO kāna mau hana a me nā hiʻohiʻona noiʻi e pili ana:
Ke kalaiwa ʻana i nā lako mīkini nui:
Hoʻohana pinepine ʻia nā motika synchronous kiʻekiʻe e hoʻokele i nā mea hana nui i ka hana ʻoihana, e like me nā compressors, pumps, fans, a me nā wili. Pono kēia mau mea hana i ka mana kiʻekiʻe a me nā hiʻohiʻona hana paʻa, a hāʻawi nā motika synchronous high-voltage i ka mana hilinaʻi i kēia hihia.
Noi mea hana:
I ka ʻoihana mana, hoʻohana ʻia nā motika synchronous kiʻekiʻe e like me nā generator synchronous. I loko o nā hale mana hydroelectric, nā mana wela, a me nā mea kanu mana ʻē aʻe, he noi maʻamau ia e hoʻohana i nā motika synchronous kiʻekiʻe-volt e hana i ka uila.
