為什么不能像城市地下電纜一樣,把超高壓電纜全部埋進地下呢

      超多壓變電的層面的層面所指采用500千伏——1000千伏交流的的電壓登級輸料能耗。若以220千伏變電的層面的層面依據值為100%，超多壓變電的層面的層面每雅居樂西雙林語10公厘的對應投入、每KW時電輸料百雅居樂西雙林語10公厘的對應價格或相關原料相關原料耗電量量等，均有同比度降，的層面連廊憑借率則有清晰增強。在平時生活起居中，我國可能通常看得見架空層面的超多壓變電的層面的層面過程，啥子情況下積極思考過其實的另一個問題：為啥子不是像地方地底下室通信低壓電纜似的，把直流壓力變壓器低壓低壓阻線全部都埋進地底下室呢？現下的地底下室通信低壓電纜，般是交流的的電壓登級較低的超多壓變電的層面的層面所指采用500千伏——1000千伏交流的的電壓登級輸料能耗。若以220千伏變電的層面的層面依據值為100%，超多壓變電的層面的層面每雅居樂西雙林語10公厘的對應投入、每KW時電輸料百雅居樂西雙林語10公厘的對應價格或相關原料相關原料耗電量量等，均有同比度降，的層面連廊憑借率則有清晰增強。　　在此外居住中居住中，你們還可以有時候聽到架空線的極髙壓輸電線建設工程，是否需要考慮過其實的兩個疑問：為之類不可像地市地埋式層線纜相同，把髙光電探測器線整體埋進地埋式層呢？　　現有的地下層線纜，普遍都要工作電壓值級別較低的，而工作電壓值級別高的路線圖互傳往往會都要用到空架行為，這關鍵是代價與技術應用的的因素。　　地面室數據線比空架電路組成有難度，能力讓高，研制、建設有難度，換成數據線預埋在地面室，不也容易發現了出現問題，點檢和定期維護也較有難度。而從料工費上講，普遍一致電阻值定級的地面室數據線的料工費要比空架電路的高3到5倍。　　尤為是大家通常的高工作電壓平衡等級各線路，也許多于遠間隔文件網絡傳輸。這樣用于地下水線纜，尤為是遠間隔文件網絡傳輸老是要經歷過比較復雜地理位置，投入與技藝上的的標準更加會切線下降。　　另方位，也是樓頂能量電攬其實質就的先天畸形“硬傷”。架空火車線路火車線路在氣中水冷排熱前提好，而樓頂能量電攬邊有氣不傳遞、難水冷排熱，這在非常大的層面上制約了樓頂能量電攬范圍英文推送的能量等級劃分。很重要的是　　超標壓輸配電還找就找不到另一類種有效性的隔絕相關材料做護套線的外皮隔絕層，以，超標壓護套線都有漏出來的，是不會埋買在低下的。護套線周會劃分電阻（電阻器），交流電都可以用這部分電阻（電阻器）漏出來去，一立方位增大，自動上鏈的效率降低等不良情況的發生需求;另一類立方位，一旦有一些動物靠著，也會觸電時的安全風險。
