聚丙烯(MPP)電力電纜保護管

 

電力電纜用(yòng)非開挖改性聚丙烯(MPP)保護管是以改型聚丙烯爲主要原材料。采用(yòng)特殊配方和(hé)加工工藝制造的(de)新型塑料管道。具有強度高(gāo)、耐溫性能好、穿放電纜容易、施工簡
便、節省費用(yòng)等一系列優點。改性聚丙烯非開挖廣泛用(yòng)作電力電纜和(hé)通(tōng)訊電纜的(de)保護管.作爲托管施工更顯産品特性,它符合現代城(chéng)市的(de)發展要求,适合埋深在2-18m範圍。應用(yòng)非開挖鋪管技術具有不污染環境、不影(yǐng)響交通(tōng)、對(duì)地層結構破壞小。施工安全可(kě)靠、周期短、無需運輸和(hé)堆放雜(zá)土、成本低、社會效益與經濟效益顯著等特點,應用(yòng)領域很寬。改性MPP電力電纜護套管采用(yòng)非開挖技術進行施工。既保證了(le)管網的(de)可(kě)靠性.降到了(le)管網的(de)故障率。同時(shí)也(yě)使市容環境得(de)到大(dà)大(dà)改善。

 

電力電纜管又名電纜管、電纜保護管、水(shuǐ)泥電纜管、電力排管、電力電纜保護管等。

電力電纜管的(de)突出特點是強度高(gāo)、摩擦阻力小,比普通(tōng)管強度高(gāo)40%,管體的(de)抗折荷載≥12000N,外壓荷載≥15000N,,可(kě)用(yòng)于各種級别的(de)道路敷設使用(yòng),内壁與電纜的(de)摩擦阻力小是電力電纜管的(de)最突出優點,其摩擦系數<0.35,明(míng)顯低于玻璃鋼、PVC等其它類别電纜管。電力電纜管通(tōng)纜時(shí)減少了(le)工井的(de)數量,降低了(le)工程造價、增加了(le)電纜牽引長(cháng)度。

電力電纜管優勢

電力電纜管消化(huà)吸收國内先進水(shuǐ)平,采用(yòng)電擴孔等先進工藝,用(yòng)高(gāo)品質的(de)維綸纖維爲基礎材料,融入植物(wù)纖維、高(gāo)強高(gāo)摩維尼綸等原料,選高(gāo)号水(shuǐ)泥作爲主原料,通(tōng)過抄取卷制而成的(de)高(gāo)新增強電纜保護管。 電力電纜管的(de)生産過程基本相同,都是通(tōng)過無上毛布抄取工藝生産,原材料爲

維綸纖維、高(gāo)标号水(shuǐ)泥及其它高(gāo)強高(gāo)彈模纖維,因此強度都很高(gāo)。電力電纜管是通(tōng)過高(gāo)速抛光(guāng)機在管子内壁抛出緻密光(guāng)滑面來(lái)達到減小摩擦阻力的(de)目的(de)。而電纜保護管則是在管子内壁塗覆一層石墨乳潤滑膜,當電纜穿過時(shí)石墨乳潤滑膜受力斷裂而産生滑移面,這(zhè)些滑移面改變了(le)管内壁與電纜之間的(de)摩擦方式,從而達到了(le)減少摩擦阻力的(de)目的(de)。

電力電纜管産品特點

電力電纜管除具備維綸纖維水(shuǐ)泥電纜管的(de)優良性能外還(hái)具備以下(xià)特點:

一、電力電纜管載流量高(gāo)、熱(rè)阻系數低。

二、電力電纜管使用(yòng)時(shí),與電纜間的(de)摩擦系數低,電纜穿過時(shí)更方便。

三、電力電纜管加長(cháng)了(le)井距,減低了(le)工井數量,降低了(le)工程成本 。

 

 

優點特性

 

具有抗高(gāo)溫、耐外壓的(de)特點,适用(yòng)于10KV以上高(gāo)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(yòng)于城(chéng)鎮電力電纜、建築給排水(shuǐ)敷設等領域。
MPP管無需開挖施工,管材熱(rè)熔焊接柔性接頭,焊接頭強度高(gāo).可(kě)超長(cháng)度高(gāo)牽引力托管。
韌性好。具有優良的(de)抗地層沉降以及抗震性能,常用(yòng)管材分(fēn)爲普通(tōng)型和(hé)加強型。普通(tōng)型适用(yòng)于開挖鋪設施工和(hé)非開挖穿越施工埋深小于4m的(de)工程;加強型使用(yòng)于非開挖穿越施工埋深大(dà)于4m的(de)工程。
