PC電線管和PVC電線管的區(qū)別：1、材質(zhì)不同：PVC管的主要成份為聚百氯乙烯；PC管的主要成分為聚碳酸酯。2、兩種線管用途不同：度PVC管好煨彎，一般使用小口徑管路，用于室外監(jiān)控、報(bào)警等線路的保知護(hù)；PC管不好煨彎，一般用于強(qiáng)弱電管路的預(yù)埋。3、理化性質(zhì)道不同：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；PC管具有突出的抗沖擊能力，耐蠕變和尺回寸穩(wěn)定性好，耐熱。PVC樹脂塑料制品突出優(yōu)點(diǎn)是難燃性、耐磨性、抗化學(xué)腐蝕性、氣體水汽低滲漏性好。此外綜合機(jī)械性能、制品透明性、電絕緣性、隔熱、消聲、消震性也好，是性能價(jià)格比**為優(yōu)越的通用型材料屬。缺點(diǎn)是熱穩(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><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。

三、PVC材質(zhì)電線管電路施工注意事項(xiàng)1.電線管不得破損、有毛刺。2.如走暗線，開槽的深度及寬度≥電線管的。3.開槽時(shí)不得割斷鋼筋。4.如需要做防水，應(yīng)先做防水。5.電管線管內(nèi)電線應(yīng)分色，不得破損，扭結(jié)。6.線管應(yīng)固定，間距不大于800毫米。7.線管與暗盒連接應(yīng)用鎖扣。8.線管之間連接應(yīng)用直接，并且用**膠水。9.線管內(nèi)的電線截面積之和不大于線管截面積的40%。10.強(qiáng)弱電插座間距不大500毫米。11.強(qiáng)弱電管交叉時(shí)，應(yīng)做屏蔽保護(hù)。12.電線管與水管及燃?xì)夤芡黄矫鏁r(shí)間距≥100毫米，不同平面時(shí)間距≥50毫米。13.電器插座與燃?xì)夤荛g距≥150毫米。14.線管內(nèi)電線應(yīng)能抽動(dòng)。15.電線管不得走直角彎或死彎。應(yīng)走月亮彎。可以減少套管電容，提高套管的電暈電壓和滑閃電壓。當(dāng)電壓等級(jí)較高時(shí)。成都川路pvc電線套管批發(fā)廠家</p><p style="text-indent:25px">一般而言，電線護(hù)套管可分為單一電線護(hù)套管、復(fù)合電線護(hù)套管、電容式電線護(hù)套管、不銹鋼護(hù)套管。成都川路pvc電線套管批發(fā)廠家</p><p> 而提到套管，電線管的選擇則不可避免。目前常見的電線管有金屬管和pvc管，金屬管硬度大，抗壓性好；pvc管韌性好、絕緣性好，價(jià)格優(yōu)惠，更容易施工。兩種電線管算是各有千秋，不分伯仲，選哪一種主要看電線安裝的環(huán)境是怎樣的。然后，在選購(gòu)電線管時(shí)，除了確定好類型外，也要注意一些分辨電線管質(zhì)量的小技巧。比如拿到一個(gè)線管，先看產(chǎn)品上的標(biāo)志（生產(chǎn)商名稱、廠址、型號(hào)、規(guī)格等）是否和合格證上的一致；然后看線管外觀是否完整，如果有破損、刮痕、氣泡、污漬等現(xiàn)象，慎重購(gòu)買。成都川路pvc電線套管批發(fā)廠家</p></p><br
