相對來說，PVC管的應(yīng)用更加大面積一些，因為施工更為方便，但是出于更加安全和更好隔絕強弱電干擾的考慮，鋼管會更好一些。用哪種電線套管都不是問題，比較大的問題還在于怎么用這些電線套管。記住一個關(guān)鍵指標，線管內(nèi)的電線不管幾條，占據(jù)線管內(nèi)徑比例不超過40%，這點很關(guān)鍵。(1)電線是會發(fā)熱的，如果線管內(nèi)的電線太密集，就容易引發(fā)安全事因。(2)太過密集，不方便日后線路檢修和維護，因為太過密集，想要把有問題的電線抽出來是非常困難的。四川聯(lián)塑pvc電線套管穿線管環(huán)氧涂塑層更有效的解決了輸水、埋地和酸、堿、鹽對金屬管道的腐蝕，使用年限可達50年以上。</p><div

PVC電線管的套管接頭一定要使用膠粘劑么？一定要使用膠粘劑。正規(guī)的做法應(yīng)該是：先把所有的沒有穿電線的保護管都埋入墻內(nèi)，天花板內(nèi)，然后，把線槽用水泥封掉，等到裝修好后，然后才從接線暗盒中穿電線。把電線穿好后再埋保護管，電線就變成一次性的了。以后想換新電線的話，根本抽不出來，不能換新電線。只能報廢。為了保護電纜，電纜敷設(shè)時在易受外力損傷的部位要加裝保護管。通常使用的保護管有鋼管和硬質(zhì)塑料管。保護管的內(nèi)徑不應(yīng)小于電纜外徑的。管壁厚度不小于2mm。硬質(zhì)塑料管不能用在溫度過高和過低的場所。通過基礎(chǔ)（包括地面或樓板）的保護管，內(nèi)徑在32mm及以下時，用鋼管保護。 </p><p> 穿線管全稱“建筑用絕緣電工套管”，通俗地講是一種白色的硬質(zhì)PVC線管，防腐蝕、防漏電、穿電線用的管子。分為塑料穿線管、不銹鋼穿線管、碳鋼穿線管。用于室內(nèi)正常環(huán)境和在高溫、多塵、有震動及有火災(zāi)危險的場所。也可在潮濕的場所使用。不得在特別潮濕，有酸、堿、鹽腐蝕和有危險的場所使用。執(zhí)行標準：JG3050-1998。通俗地講是一種白色的硬質(zhì)PVC膠管，防腐蝕、防漏電、穿電線用的管子。現(xiàn)在常用PE波紋管做“電工套管”，質(zhì)優(yōu)價廉，美觀便捷。材質(zhì)為304不銹鋼或301不銹鋼，用作電線、電纜、自動化儀表信號的電線電纜保護管，規(guī)格從3mm不銹鋼穿線管(3張)到150mm。超小口徑不銹鋼穿線管（內(nèi)徑3mm-25mm）主要用于精密光學(xué)尺之傳感線路保護、工業(yè)傳感器線路保護，具有良好的柔軟性、耐蝕性、耐高溫、耐磨損、抗拉性。電容式電線護套管由電容心子、瓷套、金屬附件和導(dǎo)體構(gòu)成。</p><div

第二點，正確進行施工安裝PVC電力管的生產(chǎn)廠家一般標配有直接、彎頭、三通等配件，在施工時如遇長度不夠應(yīng)用直接進行連接。有些工人為了省事往往不用彎頭、直接頭，采用手工掰彎或2根管子直接聯(lián)穿，都會一定程度影響穿管效果;管子末端到開關(guān)底盒處，應(yīng)當穿進底盒。有些工人先裁料后穿管，管子末端未能穿進底盒，而相差一截，此處末端和中間一樣，不允許有線材暴露在管外受水泥侵蝕，必須要求管件穿進開關(guān)底盒;遇有彎曲時，標準角度(如90)可用彎頭進行連接，也可以用彈簧將線管彎曲成任意角度。成都正規(guī)pvc電線套管定制</p></p><br
