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，不能換新電線。只能報廢。為了保護(hù)電纜，電纜敷設(shè)時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高和過低的場所。通過基礎(chǔ)（包括地面或樓板）的保護(hù)管，內(nèi)徑在32mm及以下時，用鋼管保護(hù)。 </p><p> PVC穿線管主要成份為聚氯乙烯，加入其他成分來增強其耐熱性、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)用價值。聚氯乙烯材料生產(chǎn)過程中，勢必添加幾種助劑，如穩(wěn)定劑，增塑劑等等，倘若全部采用環(huán)保助劑。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。</p><div

三、使用范圍不同1、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?？諝馇惶坠苡糜?0千伏及以下電壓等級，導(dǎo)體與瓷套之間有空氣腔作為輔助絕緣，可以減少套管電容，提高套管的電暈電壓和滑閃電壓。2、電工套管：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。電工套管：聚氯乙烯加入阻燃材料做成的一種白色不透明的穿線管，一、執(zhí)行標(biāo)準(zhǔn)：JG/T3050-1998二、產(chǎn)品規(guī)格:分為輕型-205、中型-305、重型-405三種。1、輕型-205外徑￠16mm-￠50mm2、中型-305外徑￠16mm-￠50mm3、重型-305外徑￠16mm-￠50mm（定長一般為4m，特殊規(guī)格可按客戶定做）；具有良好的柔軟性、耐蝕性、耐高溫、耐磨損、抗拉性。四川聯(lián)塑pvc電線套管質(zhì)量</p><p

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，機(jī)械強度高，可以任何角度安裝,抗潮氣性能好，結(jié)構(gòu)和維修簡單,可不用下套管，還可將心子下端車削成短尾式，縮小其尺寸。缺點是在高電壓等級時，絕級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、自動化儀表信號的電線電纜保護(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。四川聯(lián)塑pvc電線套管質(zhì)量</p></p><br
