220kV Papalua Loop Transmission Tower
Ka makou hana
⦁ He hui mana uila hoʻohui ʻia ʻo Kina, hāʻawi nui i nā huahana uila like ʻole i nā ʻoihana hoʻohana ikehu kūloko a me nā ʻāina ʻē a me nā mea kūʻai ʻoihana hoʻohana kiʻekiʻe.
⦁ Mea hana kūikawā ma ke kahua o ka hale kiaʻi / pou laina no ka hoʻouna ʻana a me ka hāʻawi ʻana i ka uila, ka hale kiaʻi kelepona / pou, ka hale substation, a me nā mea kila etc.
ʻO kā mākou ʻike
- ⦁ E EFFECTIVE i ka hana ʻana i kā mākou mau hana a me ka hāʻawi ʻana i nā lawelawe i nā mea kūʻai aku i loko a me waho.
Hale Kiekie Mana
ʻO ka hale kiaʻi hoʻouna a i ʻole ka hale kiaʻi mana (pylon uila a i ʻole pylon uila ma United Kingdom, Kanada a me nā ʻāpana o ʻEulopa) he hale kiʻekiʻe, maʻamau he hale kiaʻi kila, hoʻohana ʻia e kākoʻo i kahi laina mana ma luna.
Hoʻohana ʻia lākou i nā ʻōnaehana AC a me DC kiʻekiʻe, a hele mai i nā ʻano like ʻole a me nā nui. Aia ke kiʻekiʻe maʻamau mai 15 a 55 m (49 a 180 ft), ʻoiai ʻo ka mea kiʻekiʻe loa nā hale kiaʻi 370 m (1,214 ft) o kahi 2,700 m (8,858 ft) span o Zhoushan Island Overhead Powerline Tie. Ma waho aʻe o ke kila, hiki ke hoʻohanaʻia nā mea'ē aʻe, e like me ke kaʻa a me ka lāʻau.
Hale kiaʻi kihi-kila, hale kiaʻi kamaʻilio quadrangular truss maʻamau, me ka hoʻohana ʻana i ke kila kiʻekiʻe Q345B ma ke ʻano he mea kino hale hale kiaʻi nui, ʻo ke ʻano paʻa, ka liʻiliʻi deformation; ʻO ka pilina pili kila, nā ʻāpana māmā, hiki ke lawe lima ʻia ka hale kiaʻi a hoʻokomo ʻia ma ke kumu kūʻai haʻahaʻa. Hiki ke hoʻolako ʻia nā papa 6 kiʻekiʻe o ka paepae, kākoʻo kēlā me kēia paepae i 6 antennas.
