電線是必須套進(jìn)電線套管內(nèi)的，否則電線外層的塑料絕緣皮長時(shí)間使用后，塑料皮會(huì)老化開裂，絕緣水平很大下降，很容易引起大面積漏電，危及人身安全。此外，漏泄的電流在流入地面途中，如遇電阻較大的部位，會(huì)產(chǎn)生局部高溫，致使附近的可燃物著火，引發(fā)火災(zāi)。所以，從安全角度考慮，也必須將電線套入線管中。電線護(hù)套管主要有兩種，一種是PVC塑料電線套管，還有一種是鋼管的。不管選用哪種電線套管，都能起到非常好的電線保護(hù)作用，這也是經(jīng)過很多年驗(yàn)證的，不需要擔(dān)心。 </p><p> 電纜保護(hù)套管是電力工程中推廣使用的一種新型套管材料。隨著電力電纜埋地敷設(shè)工程的迅速發(fā)展，對電纜套管提出的更高要求，電纜保護(hù)套管是采用聚乙烯PE和質(zhì)量鋼管經(jīng)過噴砂拋丸前處理、浸塑或涂裝、加溫固化工藝制作而成。它是保護(hù)電線和電纜**常用的一種電絕緣管。因?yàn)榫哂薪^緣性能良好、化學(xué)穩(wěn)定性高、不生銹、不老化、可適應(yīng)苛刻環(huán)境而被大面積得以應(yīng)用。1、耐腐蝕，使用壽命長，可在潮濕鹽堿地帶使用。2、阻燃、耐熱性好，可在130度高溫下長期使用而不變形，遇火不燃燒。3、強(qiáng)度高、剛度高。用在行車道下直埋無需加混凝土保護(hù)層，能輥快電纜工程建設(shè)進(jìn)度。4、管材有柔性，能抵御外界重壓和基礎(chǔ)沉降所引起的破壞。5、具有良好的抗外界信號干擾性能。6、內(nèi)壁光滑，不刮傷電纜。設(shè)計(jì)采用承插式的連接方式，方便安裝連接。接頭處加橡膠密封圈封既適應(yīng)熱脹冷縮，又防止泥砂進(jìn)入。根據(jù)材質(zhì)性能可分四類：單一電線護(hù)套管、復(fù)合電線護(hù)套管、電容式電線護(hù)套管和不銹鋼護(hù)套管。</p><div

1、強(qiáng)度高、剛度高。用在行車道下直埋無需加混凝土保護(hù)層，能輥快電纜工程建設(shè)進(jìn)度。2、管材有柔性，能抵御外界重壓和基礎(chǔ)沉降所引起的破壞。3、耐腐蝕，使用壽命長，可在潮濕鹽堿地帶使用。4、阻燃、耐熱性好，可在130度高溫下長期使用而不變形，遇火不燃燒。5、內(nèi)壁光滑，不刮傷電纜。設(shè)計(jì)采用承插式的連接方式，方便安裝連接。接頭處加橡膠密封圈封既適應(yīng)熱脹冷縮，又防止泥砂進(jìn)入。家裝電線套管一般使用PVC管。電線套管主要是考慮電線的絕緣、防潮、防腐和保持通暢等性能?，F(xiàn)在**常見、**安全可行的一種線管是PVC管,但對于不能開槽的承重墻和橫梁等位置,不能使用PVC管,要使用軟管,才不會(huì)影響承重墻和橫梁的結(jié)構(gòu)。復(fù)合電線護(hù)套管的導(dǎo)體與瓷套間的內(nèi)腔充滿變壓器油，起徑向絕緣作用。成都多聯(lián)pvc電線套管批發(fā)廠家</p><p

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(diǎn)。如果真的要比道較好壞就只能從性價(jià)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(jī)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。成都多聯(lián)pvc電線套管批發(fā)廠家</p></p><br
