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(kāi)槽的深度及寬度≥電線管的。3.開(kāi)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。電線護(hù)套管，是一種絕緣保護(hù)套管，用于電線電纜外部的保護(hù)。成都川路pvc電線套管廠家直銷</p><p style="text-indent:25px">它以樹(shù)脂為基體和其他增強(qiáng)材料復(fù)合而成的絕緣套管，用于穿用電線和保護(hù)電線，故稱為電線護(hù)套管。四川川路pvc電線套管價(jià)格</p><p> 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(méi)有穿電線的保護(hù)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(hù)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(lái)，不能換新電線。只能報(bào)廢。為了保護(hù)電纜，電纜敷設(shè)時(shí)在易受外力損傷的部位要加裝保護(hù)管。通常使用的保護(hù)管有鋼管和硬質(zhì)塑料管。保護(hù)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(guò)高和過(guò)低的場(chǎng)所。通過(guò)基礎(chǔ)（包括地面或樓板）的保護(hù)管，內(nèi)徑在32mm及以下時(shí)，用鋼管保護(hù)。四川川路pvc電線套管價(jià)格</p></p><br
