直埋電纜敷設有哪些要求

直埋電攬敷設有的規范？（1）挖溝的溝底是膨松的持力層，要是石子或硬質的臟物要鋪100mm厚的軟土或砂層。低壓數據線線身上的的沙石如內含結垢低壓數據線線合金包皮，應排除和換土，埋深應不不大于0.7m，殺手穿越農地應該把冷卻水不不大于1m。在機遇筑物物、與地埋式筑物物交疊及繞開地埋式筑物物處，可淺埋，但應運用養護處理，低壓數據線線應埋于凍持力層以內，當受必備條件的限制時，應運用放到低壓數據線線受板材損害的處理。（2）電力電纜電線敷設后，上述要鋪100mm厚的軟土或沙子，再蓋起來水泥c30混疑土土防護板，蓋住屏幕寬度匹配應不超電力電纜電線二邊其他各50mm，或用磚配用水泥c30混疑土土防護板。
