一、電線管套作用1、方便以后能把電線抽出來如果把電線直接埋進(jìn)水泥砂漿里，這就成了“死線”，后期如果要進(jìn)行線路維護(hù)、更換和家庭智能化設(shè)備等，就不可能了，成都正規(guī)pvc電線套管廠家直銷。小編不否認(rèn)現(xiàn)在多數(shù)家里的裝修，盡管使用了穿線管，但還是做成了“死線”，根本抽出來，但如果不這樣做，可能永遠(yuǎn)也抽不出來。2、保護(hù)電線的絕緣層如果直接埋進(jìn)水泥砂漿中，水泥里的硅酸鹽可能會(huì)腐蝕電線的絕緣層，導(dǎo)致電線絕緣下降而造成短路，成都正規(guī)pvc電線套管廠家直銷，而且一旦受潮，漏電的現(xiàn)象就難以避免。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，成都正規(guī)pvc電線套管廠家直銷，心子中不易消除氣隙，以致造成局部放電電壓低。成都正規(guī)pvc電線套管廠家直銷</p><div

為了保護(hù)電纜，電纜敷設(shè)時(shí)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(chǎng)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(shí)，用鋼管保護(hù)。電力電纜一般在下列場(chǎng)所加裝保護(hù)管：（1）電纜引入、引出建筑物、隧道、溝道部位；（2）電纜穿過樓板、墻壁、道路的穿越段；（3）引至電桿或沿墻敷設(shè)的電纜離地面2m高的一段和易受機(jī)械損傷的其他部位。成都正規(guī)pvc電線套管廠家直銷具有良好的柔軟性、耐蝕性、耐高溫、耐磨損、抗拉性。</p><div

對(duì)于走在頂上的電源線必須穿線管而過，而且對(duì)吊頂?shù)哪君埞且M(jìn)行防火、防蟲等兩項(xiàng)處理，以免日后給業(yè)主帶來麻煩。首先選擇電線時(shí)要用銅線，忌用鋁線。由于鋁線的導(dǎo)電性差，通電過程中電線容易發(fā)熱甚至引發(fā)火災(zāi)。然后，布線一定要用絕緣的穿線管。如果將電線直接藏在墻內(nèi)，等于家里潛伏著一顆定時(shí)，隨時(shí)都可能漏電，發(fā)生險(xiǎn)情。當(dāng)然，各種不同的線路也相對(duì)不能走同一管線，比如電視天線，電話線等等。線路接頭不能過多，如果必須接線，要做好絕緣及防潮，如果條件允許還可以“涮錫”。裝修結(jié)束時(shí)。 </p> <p> <br /> </p><p> 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(zhǎng)，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(zhǎng)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(duì)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)。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
