一、PVC電線管規(guī)格按PVC電線品種分為硬質(zhì)管、半硬質(zhì)管和波紋管;按電線特性分為輕型、中型、重型、超重型;按電線溫度等級(jí)分為25型、05型、90/-25型等。PVC電線管公稱外徑規(guī)格，分別為：Φ16、Φ20、Φ25、Φ32、Φ40、Φ50、Φ63、Φ75、Φ110。其中，PVC電線管規(guī)格為Φ16和Φ20，一般用于室內(nèi)照明線路;PVC電線管外徑規(guī)格為Φ25，常用于插座或是室內(nèi)主線管;PVC電線管外徑規(guī)格為Φ32常用于進(jìn)戶線的線管，也用于弱電線管;PVC電線管外徑規(guī)格為Φ50、Φ63、Φ75的常用于電盤至戶內(nèi)的線管。四川康泰塑膠pvc電線套管規(guī)格型號(hào)它具有抗壓力強(qiáng)、重量輕、內(nèi)壁光滑，摩擦系數(shù)小等特點(diǎn)，在穿用電線時(shí)輕松，不損傷電線。</p><div

PVC電線管4分和6分是電線管的型百號(hào)不同的叫法，4分管也就是直徑16線管，6分管也就是直徑20線管，兩種型號(hào)在鋪設(shè)線管時(shí)都要用到的，度穿過線管的電線少就用16的，穿過線管的電線多就用20的，具體16和20管內(nèi)穿幾根線，也有標(biāo)準(zhǔn)的，一般管內(nèi)的電線的總截面專積不應(yīng)超過管內(nèi)徑截面積的40%，但在實(shí)際施工中不太根據(jù)這標(biāo)準(zhǔn)，只要電線穿進(jìn)線管內(nèi)屬不要很緊，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可以起到絕緣作用,在施工過程中如果電線表皮劃傷漏電家中的總開關(guān)是和不上的.用pvc管容易檢修,而且以后出現(xiàn)電線老化,容易更換。 </p><p> 我們知道，給電線套上一層電線管，是為了讓電線更有“安全感”，讓其不受外界環(huán)境的影響和破壞。但不少人認(rèn)為，pvc電線作為一種絕緣電線，表面已經(jīng)有了保護(hù)層，是不需要格外套管的。那pvc線纜到底還要不要套管呢？其實(shí)，無論是pvc電線還是其他類型的電線，對(duì)其進(jìn)行套管是十分有必要的。這么做的目的很簡(jiǎn)單，讓電線披上一層“外衣”，阻隔外界的污染、腐蝕、高溫、磕碰等情況，從而讓電線安安靜靜地為我們輸送電能。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。電線套管：一言以蔽之，一般是金屬材質(zhì)的。</p><div

電容式電線護(hù)套管的電容心子用膠紙制造時(shí)，機(jī)械強(qiáng)度高，可以任何角度安裝,抗潮氣性能好，結(jié)構(gòu)和維修簡(jiǎn)單,可不用下套管，還可將心子下端車削成短尾式，縮小其尺寸。缺點(diǎn)是在高電壓等級(jí)時(shí)，絕級(jí)材料和工藝要求較高，心子中不易消除氣隙，以致造成局部放電電壓低。不銹鋼護(hù)套管不銹鋼護(hù)套管，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到150mm。超小口徑不銹鋼護(hù)套管（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。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。四川康泰塑膠pvc電線套管規(guī)格型號(hào)</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。四川康泰塑膠pvc電線套管規(guī)格型號(hào)</p></p><br
