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。 </p><p> 電容式電線護套管的電容心子用膠紙制造時，機械強度高，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。不銹鋼護套管不銹鋼護套管，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管，規(guī)格從3mm到150mm。超小口徑不銹鋼護套管（內(nèi)徑3mm-25mm）主要用于精密光學(xué)尺之傳感線路保護、工業(yè)傳感器線路保護，具有良好的柔軟性、耐蝕性、耐高溫、耐磨損、抗拉性。一般而言，電線護套管可分為單一電線護套管、復(fù)合電線護套管、電容式電線護套管、不銹鋼護套管。</p><div

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。為了保護電纜，電纜敷設(shè)時在易受外力損傷的部位要加裝保護管。通常使用的保護管有鋼管和硬質(zhì)塑料管。保護管的內(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）的保護管，內(nèi)徑在32mm及以下時，用鋼管保護。 PVC管的熱穩(wěn)定性和抗沖擊性較差，無論是硬性還是軟質(zhì)PVC使用過程中容易產(chǎn)生脆性；四川多聯(lián)塑膠pvc電線套管批發(fā)價格</p><p style="text-indent:25px">2、兩種線管用途不同：度 PVC管好煨彎，一般使用小口徑管路，用于室外監(jiān)控、報警等線路的保知護；四川華邦pvc電線套管代理商</p><p>
