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(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)價廉，美觀便捷。材質(zhì)為304不銹鋼或301不銹鋼，成都川路pvc電線套管定制，用作電線，成都川路pvc電線套管定制、電纜、自動化儀表信號的電線電纜保護(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)，成都川路pvc電線套管定制、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。電線套管：單一電線護(hù)套管的絕緣結(jié)構(gòu)分為有空氣腔和空氣腔短路兩類。成都川路pvc電線套管定制</p><div

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)。根據(jù)材質(zhì)性能可分四類：單一電線護(hù)套管、復(fù)合電線護(hù)套管、電容式電線護(hù)套管和不銹鋼護(hù)套管。電線護(hù)套管，其實也叫絕緣套管，是一種復(fù)合了絕緣材料的新型的復(fù)合材料管,它以樹脂為基體和其他增強材料復(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。它具有抗壓力強、重量輕、內(nèi)壁光滑，摩擦系數(shù)小等特點，在穿用電線時輕松，不損傷電線。搬、運要比金屬鋼管和水泥管輕松、方便。施工安裝簡便，既省事又省力。耐腐蝕性能強、絕緣、非磁性、耐酸、耐堿、阻燃型、抗靜電。成都川路pvc電線套管定制電工套管：穿線管表面光滑、流體阻力小，不結(jié)垢、不宜滋生微生物。</p><div

第二點，正確進(jìn)行施工安裝PVC電力管的生產(chǎn)廠家一般標(biāo)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(jìn)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(dāng)穿進(jìn)底盒。有些工人先裁料后穿管，管子末端未能穿進(jìn)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(jìn)開關(guān)底盒;遇有彎曲時，標(biāo)準(zhǔn)角度(如90)可用彎頭進(jìn)行連接，也可以用彈簧將線管彎曲成任意角度。 </p><p> 對于走在頂上的電源線必須穿線管而過，而且對吊頂?shù)哪君埞且M(jìn)行防火、防蟲等兩項處理，以免日后給業(yè)主帶來麻煩。首先選擇電線時要用銅線，忌用鋁線。由于鋁線的導(dǎo)電性差，通電過程中電線容易發(fā)熱甚至引發(fā)火災(zāi)。然后，布線一定要用絕緣的穿線管。如果將電線直接藏在墻內(nèi)，等于家里潛伏著一顆定時，隨時都可能漏電，發(fā)生險情。當(dāng)然，各種不同的線路也相對不能走同一管線，比如電視天線，電話線等等。線路接頭不能過多，如果必須接線，要做好絕緣及防潮，如果條件允許還可以“涮錫”。裝修結(jié)束時。

PVC電線套管選擇？PVC線槽的品種規(guī)格很多，知從型號上講有：PVC-20系列、PVC-25系列、PVC-25F系列、PVC-30系列、PVC-40系列、PVC-40Q系列等。每一種型號的PVC線槽都有各自的特色和缺點。如果真的要比道較好壞就只能從性價比比較了。pvc－u絕緣阻燃電工套管GY。G=管材；Y=硬質(zhì)套管，內(nèi)其他還有B指半硬質(zhì)，W指波紋容管；3=機(jī)械性能，這里3指中型，其他還有2輕型，4重型，5超重型；15=溫度等級，一般指管材的低溫或高溫性能，其他還有-5型，-25型等等；25=公稱外徑，常見的有16，20，25，32，40，63。成都川路pvc電線套管定制</p></p><br
