1、按PVC電線品種分為硬質(zhì)管、半硬質(zhì)管和波紋管知;按電線特性分為輕型、中型、重型、超重型;2、按電線溫度等級(jí)分為25型、05型、90/-25型等。3、pvc電線管公稱外徑規(guī)格，分別為：Φ16、Φ20、Φ25、Φ32、Φ40、Φ50、Φ63、Φ75、Φ道110。其中，內(nèi)pvc電線管規(guī)格為Φ16和Φ20，一般容用于室內(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。 </p><p> PVC穿線管主要成份為聚氯乙烯，加入其他成分來增強(qiáng)其耐熱性、韌性、延展性的一種材料。PVC可分為軟PVC和硬PVC。其中硬PVC大約占市場(chǎng)的2/3，軟PVC占1/3。軟PVC一般用于地板、天花板以及皮革的表層，但由于軟PVC中含有增塑劑（這也是軟PVC與硬PVC的區(qū)別），物理性能較差（如上水管需要承受一定水壓，軟質(zhì)PVC就不適合使用），所以其使用范圍受到了局限。硬PVC不含增塑劑，因此易成型，物理性能佳，因此具有很大的開發(fā)應(yīng)用價(jià)值。聚氯乙烯材料生產(chǎn)過程中，勢(shì)必添加幾種助劑，如穩(wěn)定劑，增塑劑等等，倘若全部采用環(huán)保助劑。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。</p><div

一、指代不同1、電線套管：是一種絕緣保護(hù)套管，用于電線電纜外部的保護(hù)。2、電工套管：又稱穿線管，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。二、優(yōu)缺點(diǎn)不同1、電線套管：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。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。耐腐蝕性能強(qiáng)、絕緣、非磁性、耐酸、耐堿、阻燃型、抗靜電。2、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。熱膨脹系數(shù)小，不收縮變形。傳統(tǒng)的安裝連接方式。穿線管環(huán)氧涂塑層更有效的解決了輸水、埋地和酸、堿、鹽對(duì)金屬管道的腐蝕，使用年限可達(dá)50年以上。空氣腔內(nèi)部將發(fā)生電暈而使上述作用失效，這時(shí)采用空氣腔短路結(jié)構(gòu)。四川正規(guī)pvc電線套管定制</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。四川正規(guī)pvc電線套管定制</p><p
