電容式電線護(hù)套管：由電容心子、瓷套、金屬附件和導(dǎo)體構(gòu)成。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。

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。電線管套，非專業(yè)的人不清楚這是什么東西，這是一種電力工程中推廣使用的一種新型套管材料；</p><div

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。PC電線管和PVC電線管有什么區(qū)別?成都日豐pvc電線套管廠家直銷</p><p
