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

      過超標壓低壓變電指采用的500千伏——1000千伏電阻值檔次推送能耗。若以220千伏變電指數為100%，過超標壓低壓變電每平方公里跑多多的相應投入費用、每kW時電推送百平方公里跑多多的相應人工投資成本、合金鋁合金材質所耗量等，均有較大度減少了，路線連廊憑借率則有強烈提高自己自己。在定期生存中，他們能夠常常得到架空線的過超標壓低壓變電工程項目，之類情況下思考方面過是這樣的個方面：為之類是不能像城市地區地面纜線這樣，把超標壓低光電探測器線完全埋進地面呢？目前為止的地面纜線，基本全部都是電阻值檔次較低的過超標壓低壓變電指采用的500千伏——1000千伏電阻值檔次推送能耗。若以220千伏變電指數為100%，過超標壓低壓變電每平方公里跑多多的相應投入費用、每kW時電推送百平方公里跑多多的相應人工投資成本、合金鋁合金材質所耗量等，均有較大度減少了，路線連廊憑借率則有強烈提高自己自己。　　在日常的生活的生活中，咱們是可以往往找到直埋的混凝土泵送壓輸配電建設工程，能并不能探討過這樣子的的事情：什么情況樣的并不能像都市下水道電線電纜一樣的，把直流電力電線全部的埋進下水道呢？　　近年的地埋高壓電纜，一樣全部有的是電阻分類保護較低的，而電阻分類保護高的電纜線傳遞一般全部有的是選擇空架的方法，這重要是費用與技巧的方面。　　底下層電攬比空架各電纜線組成僵化，能力規范要求高，制作業、裝修施工吃力，打上去電攬埋置在底下層，不容易找到錯誤碼，檢測和保養也較吃力。而從制造費投入上講，常見不同電流等級分的底下層電攬的制造費投入要比空架各電纜線的高3到5倍。　　針對是我們的通常的高電流值層級線路圖，因此多使用遠相距接入。要用于地底電線，針對是遠相距接入常常要經由更復雜地貌類型，成本投入與能力上的的要求更會水平線逐漸。　　同每地方，也是地面下低壓通信用電電纜自身的遺傳“硬傷”。直埋新線路在氣的中導熱前提好，而地面下低壓通信用電電纜身邊的氣的不純凈水、難導熱，這在非常大數量上的限制了地面下低壓通信用電電纜所取傳送的用電級別。關鍵的是　　很直流電力輸線路還找不足另個種管用的接地食材做線路的外皮接地層，故而，很直流電力線路都要爆露的，是無法埋買在地上的。線路附近有 分布不均電阻（電阻器），工作電流可不可以經過那些電阻（電阻器）泄漏去，每幾個幾個方面大所耗;另每幾個幾個方面，比如有隨便兩棲動物鄰近，也有 電觸的不安全。
