聚丙烯(MPP)電力電纜保護管
電力電纜用非開挖改性聚丙烯(MPP)保護管是以改型聚丙烯為主要原材料。采用特殊配方和加工工藝制造的新型塑料管道。具有強度高、耐溫性能好、穿放電纜容易、施工簡
便、節省費用等一系列優點。改性聚丙烯非開挖廣泛用作電力電纜和通訊電纜的保護管．作為托管施工更顯產品特性，它符合現代城市的發展要求，適合埋深在2-18m范圍。應用非開挖鋪管技術具有不污染環境、不影響交通、對地層結構破壞小。施工安全可靠、周期短、無需運輸和堆放雜土、成本低、社會效益與經濟效益顯著等特點，應用領域很寬。改性MPP電力電纜護套管采用非開挖技術進行施工。既保證了管網的可靠性．降到了管網的故障率。同時也使市容環境得到大大改善。
電力電纜管又名電纜管、電纜保護管、水泥電纜管、電力排管、電力電纜保護管等。
電力電纜管的突出特點是強度高、摩擦阻力小，比普通管強度高40%，管體的抗折荷載≥12000N，外壓荷載≥15000N，，可用于各種級別的道路敷設使用，內壁與電纜的摩擦阻力小是電力電纜管的最突出優點，其摩擦系數<0．35，明顯低于玻璃鋼、PVC等其它類別電纜管。電力電纜管通纜時減少了工井的數量，降低了工程造價、增加了電纜牽引長度。
電力電纜管優勢
電力電纜管消化吸收國內先進水平，采用電擴孔等先進工藝，用高品質的維綸纖維為基礎材料，融入植物纖維、高強高摩維尼綸等原料，選高號水泥作為主原料，通過抄取卷制而成的高新增強電纜保護管。 電力電纜管的生產過程基本相同，都是通過無上毛布抄取工藝生產，原材料為
維綸纖維、高標號水泥及其它高強高彈模纖維，因此強度都很高。電力電纜管是通過高速拋光機在管子內壁拋出致密光滑面來達到減小摩擦阻力的目的。而電纜保護管則是在管子內壁涂覆一層石墨乳潤滑膜，當電纜穿過時石墨乳潤滑膜受力斷裂而產生滑移面，這些滑移面改變了管內壁與電纜之間的摩擦方式，從而達到了減少摩擦阻力的目的。
電力電纜管產品特點
電力電纜管除具備維綸纖維水泥電纜管的優良性能外還具備以下特點：
一、電力電纜管載流量高、熱阻系數低。
二、電力電纜管使用時，與電纜間的摩擦系數低，電纜穿過時更方便。
三、電力電纜管加長了井距，減低了工井數量，降低了工程成本 。
優點特性
具有抗高溫、耐外壓的特點,適用于10KV以上高壓輸電線電纜排管管材。
非開挖工程MPP排管(改性聚丙烯管)廣泛應用于城鎮電力電纜、建筑給排水敷設等領域。
MPP管無需開挖施工,管材熱熔焊接柔性接頭,焊接頭強度高．可超長度高牽引力托管。
韌性好。具有優良的抗地層沉降以及抗震性能，常用管材分為普通型和加強型。普通型適用于開挖鋪設施工和非開挖穿越施工埋深小于4m的工程;加強型使用于非開挖穿越施工埋深大于4m的工程。
具有以上優點
具有優良的電氣絕緣度。抗拉、抗壓性能比HDPE高
質輕、光滑、摩擦阻力小，可熱熔焊接對接。長期使用溫度-5-90℃。
應用領域
