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(dòng)及有火災(zāi)危險(xiǎn)的場(chǎng)所。也可在潮濕的場(chǎng)所使用。不得在特別潮濕，有酸、堿、鹽腐蝕和有危險(xiǎn)的場(chǎng)所使用。執(zhí)行標(biāo)準(zhǔn)：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?，F(xiàn)在常用PE波紋管做“電工套管”，質(zhì)優(yōu)價(jià)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(dòng)化儀表信號(hào)的電線電纜保護(hù)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(hù)、工業(yè)傳感器線路保護(hù)，具有良好的柔軟性、耐蝕性、耐高溫、耐磨損、抗拉性。成都川路塑膠pvc電線套管價(jià)格搬、運(yùn)要比金屬鋼管和水泥管輕松、方便。施工安裝簡(jiǎn)便，既省事又省力。</p><div

PVC電線管、A管和B管有什么區(qū)別？?jī)烧邊^(qū)別如下：1、A管相對(duì)B管用料要好些，強(qiáng)度高點(diǎn)copy，厚度也厚一點(diǎn)。2、A管相對(duì)B管，價(jià)格更高一些。3、A管通常用作排水，B管通常用作通風(fēng)。管材優(yōu)點(diǎn)1、具有較好的抗拉、抗壓強(qiáng)度：但其柔性不如其他塑料管。2、流體阻力小：PVC-U管材的管壁非常光滑，對(duì)流體的阻力很小，其粗糙系數(shù)*為，其輸水能力可比同等管徑的鑄百鐵管提高20%，比混凝土管提高40%。3、耐腐蝕性、耐藥品性優(yōu)良：PVC-U管材具有優(yōu)異的耐酸，耐堿，耐腐蝕，不受潮濕水份和土壤酸堿度的影響，管道鋪設(shè)時(shí)不需任何防腐處理度。4、具有良好的水密性：PVC-U管材的安裝，不論采用粘接還是橡膠圈連接，均具有良好的水密性。 </p><p> 一、電線管套作用1、方便以后能把電線抽出來如果把電線直接埋進(jìn)水泥砂漿里，這就成了“死線”，后期如果要進(jìn)行線路維護(hù)、更換和家庭智能化設(shè)備等，就不可能了。小編不否認(rèn)現(xiàn)在多數(shù)家里的裝修，盡管使用了穿線管，但還是做成了“死線”，根本抽出來，但如果不這樣做，可能永遠(yuǎn)也抽不出來。2、保護(hù)電線的絕緣層如果直接埋進(jìn)水泥砂漿中，水泥里的硅酸鹽可能會(huì)腐蝕電線的絕緣層，導(dǎo)致電線絕緣下降而造成短路，而且一旦受潮，漏電的現(xiàn)象就難以避免。 PVC管的熱穩(wěn)定性和抗沖擊性較差，無論是硬性還是軟質(zhì)PVC使用過程中容易產(chǎn)生脆性；</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="成都川路塑膠pvc電線套管價(jià)格,pvc電線套管"

PVC電線管常用的有4分和6分管。4分管也就是直徑16毫米線管，6分管也就是直徑20毫米線管，壁厚要視質(zhì)量zhidao而定，好的厚差的薄，一般大約為。兩種型號(hào)在鋪設(shè)線管時(shí)都要用到的，穿過線管的電線少就用16毫米線管的，穿過線管的電線多就用20毫米線管的，具體16分和20分管內(nèi)穿幾根線，也有標(biāo)準(zhǔn)的。一般管內(nèi)的電線的總截面積不應(yīng)超過管內(nèi)徑截面積的40%，只要電線穿進(jìn)版線管內(nèi)不要很緊，要留一定的空間，因?yàn)橐o電線發(fā)熱留下一點(diǎn)空間，保證電線的使用。pvc穿線管安裝注意事項(xiàng)1、當(dāng)然**重要的是要使用穿線管埋線。2、電路走線應(yīng)該把握“兩端間**近距離走線”，不能無故繞線，這樣不但會(huì)造成死線，還會(huì)增大電改投入。3、一根穿線管中不要穿太多線，穿線后都應(yīng)該拽一下，看看是否可以輕松拽動(dòng)。4、線路有接頭必需在接頭處留暗盒扣面板，日后更換和維修都方便。5、管徑小于25的PVC穿線管拐彎應(yīng)用彎管器，不能加彎頭拐彎。復(fù)合電線護(hù)套管的導(dǎo)體與瓷套間的內(nèi)腔充滿變壓器油，起徑向絕緣作用。四川多聯(lián)塑膠pvc電線套管</p><p
