ʻO ka laina ma luna e pili ana i ka laina hāmama ma luna o ke poʻo i hoʻonohonoho ʻia ma ka ʻāina, ʻo ia ka laina mana uila i hoʻonohonoho ʻia ma luna o ka hale kiaʻi me nā insulators a me nā lako mana.Ua hana ia me ka uea a me ka lepo uea (overhead ground wire), hale kiaʻi, insulator, hardware, a me nā ʻāpana ʻē aʻe o ke kahua o ka hale kiaʻi, heleuma a me ka mea paʻa, ua hana ʻia ka uea mai ka metala conductive maikaʻi, aia ka ʻāpana mānoanoa (i mālama i ke kahe kahe kūpono) a me ka radius nui o ka curvature (e hōʻemi i ka hoʻokuʻu ʻana o ka corona) a me ka hoʻoili uila ultra-kiʻekiʻe e hoʻohana pono i ka conductor split;Hoʻokumu ʻia ke kaula insulator me kahi kaula insulator hoʻokuʻu (a i ʻole bar), pono e hoʻokō i nā koi o ka ikaika insulation a me ka ikaika mechanical, a ʻo ka helu o nā insulators i kēlā me kēia kaula e hoʻoholo ʻia e ka pae uila uila.ʻO nā pou a me nā hale kiaʻi, ka hapa nui i hana ʻia me ke kila a i ʻole ka hoʻoikaika ʻia ʻana, ʻo ia nā hale kākoʻo nui no nā laina hoʻouna ma luna…
ʻIke mākou ua kau ʻia nā laina o luna ma luna o ka uea hāmama ma ka honua, he kiʻekiʻe ko ka honua, akā, i kēia manawa, ʻaʻole ʻike ʻia mai ka wā ma mua, ua nalo nā laina o luna mai ko mākou ʻike ʻana, ʻaʻole manaʻo ka nalowale ʻana ʻaʻole i luna. laina ma ʻaneʻi, ʻoiaʻiʻo, akā ua laina kēia ma luna o ka lepo, a kanu ʻia i ka lepo.He aha ka hewa ma ʻaneʻi?He aha ka maikaʻi o ka hele ʻana o ka laina ma luna o ka honua?A laila, e kamaʻilio pū me ʻoe e pili ana i ka laina overhead i ka ʻike pili honua, manaʻolana wau hiki iā ʻoe ke hoʻomaopopo.
Ma mua o ka hoʻomaka ʻana e kamaʻilio e pili ana i nā pono o ka laina lewa i loko o ka lepo, e nānā mua mākou i kekahi mau hihia nūhou: ʻo Tongzhou District kahiko aupuni ma ke komohana ʻāpana, Songzhuang Road, Defense South Road Defense North road, Hongyun Science and Technology Park alanui a me nā alanui ʻē aʻe 83. , "ka laina lewa uila i loko o ka honua" ma kēia mau alanui, ʻo ka lōʻihi o ke alanui he 45.398 kilomita, ʻo ka hoʻopukapuka pāhana i manaʻo ʻia: 137,425,900;ʻO ke alanui ʻoihana ʻo Baotou ma ka ʻaoʻao hema o ke alanui nui (mai ke alanui Dongmen a i ke alanui Zhanbei) pono e komo i ka ʻāina;Ke hana pū nei ʻo Shanghai Xuhui lāua ʻo Changning, Sichuan, e hoʻolei i ka laina ma luna o ka ʻāina a me ka hana hoʻohui…
No ke aha e komo ai nā uwea ma luna o ka honua?No laila he aha nā pōmaikaʻi o ke komo ʻana i ka laina ma luna?Pono mākou e hoʻomaopopo i ke kumu o ka laina overhead i loko o ka honua, ua hōʻike ʻia he nui nā wahi e pono ai ka laina ma luna o ka honua, no ka mea maʻalahi ka maʻalahi o ka laina ma luna o nā kūlana kaiapuni, no laila e pau pinepine nā laina o kēia mau wahi. "ʻAʻole ʻaʻa ka hale kūʻai e hoʻohana i nā mea hana mana kiʻekiʻe", makaʻu i ka hekili a me ka ua, e make ai.Eia naʻe, ma hope o ka laina o luna i loko o ka lepo, ʻaʻole like ia, ma o ka hoʻoponopono hou ʻana, ke ala ma nā ʻaoʻao ʻelua o ka mea hou, kūpono i ka hoʻomaikaʻi ʻana i ke kaiapuni kūlanakauhale;E hōʻalo pono i ka hāʻule ʻana o ka ʻoihana pūnaewele i hoʻokumu ʻia e ka ʻino a me ka pōʻino o waho, e hōʻemi nui i ka helu a me ke ʻano o ka hemahema o ka mana, ʻoiai e hoʻomaikaʻi ana i ka palekana a me ka hilinaʻi o ka mana mana, he pōmaikaʻi nui ia no mākou.
