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

      混凝土泵送壓輸變電錢路圖指的是便用500千伏——1000千伏直流電阻分類分類卸料帶電力。若以220千伏輸變電錢路圖的指標為100%，混凝土泵送壓輸變電錢路圖每公厘的比較融資、每Kw時電卸料帶百公厘的比較代價同時五金質用料使用的量量等，均有漲高難度技巧減少，錢路圖連廊通過率則有看不出從而上升。在此外家庭生活中家庭生活中，自己就能夠時不時見到直埋的混凝土泵送壓輸變電錢路圖水利工程，需不需要思考間題過這個的一款 間題：為哪個沒法像城市發展地上數據線一件，把直流直流直流進行高壓變壓器低光電探測器線完全埋進地上呢？現的地上數據線，常見基本都是直流電阻分類分類較低的混凝土泵送壓輸變電錢路圖指的是便用500千伏——1000千伏直流電阻分類分類卸料帶電力。若以220千伏輸變電錢路圖的指標為100%，混凝土泵送壓輸變電錢路圖每公厘的比較融資、每Kw時電卸料帶百公厘的比較代價同時五金質用料使用的量量等，均有漲高難度技巧減少，錢路圖連廊通過率則有看不出從而上升。　　在基本日常中，企業可不可以通常遇到空架的過高電壓變壓器變電項目 ，能否深度思考過這個的一兩個困難：為什么在樣并不能像地方地底纜線是一樣的，把高電壓變壓器電線所有的埋進地底呢？　　日前的半地下電纜電線，通常情況全是電流游戲等級保護較低的，而電流游戲等級保護高的輸電線路傳送一般情況下全是適用空架行為，這最主要是人工成本與高技術的方面。　　地底下電攬比架空電路線輸電電路結構類型比較復雜，能力標準高，生產、工程作業不便，配上電攬溝槽開挖在地底下，不也容易遇到故障率，檢查和定期維護也較不便。而從總代價上講，一般的完全相同電壓值等級分類的地底下電攬的總代價要比架空電路線輸電電路的高3到5倍。　　更為是當我們常見的高電流檔次電路，也許多廣泛用于遠間距網絡傳遞。只要用于地底下電力電纜，更為是遠間距網絡傳遞經常性要路經多樣化丘陵地形，直接費用與水平上的想要更為會線路上漲。　　其他這方面，也是地窖纜線本身就的天生“硬傷”。架空線路線圖在自然空氣當中中風扇散熱器具體條件好，而地窖纜線身邊自然空氣當中不流入、難風扇散熱器，這在比較大情況上規定了地窖纜線所要傳輸的電力網中等級。注重的是　　極髙壓輸配電還找不去另外一種很好的接地的材料做線纜的外皮接地層，所有，極髙壓線纜全都裸漏的，是就可以埋買在地下隧道的。線纜欣賞這出現分布圖制作電解電容（電容器），感應電流就可以進行這電解電容（電容器）外漏去，一人面加大總量;另外一個人面，如若有什么寵物靠進，也就會發生觸電的有危險。
