二、PVC電線管特性：PVC電線管（亞馬遜塑業(yè)）按型號(hào)分輕、中、重規(guī)格主要有：1.絕緣性能好：PVC電工套管絕緣性好、抗電流擊穿電壓高，能抵受25千伏電壓而不被擊穿，所以PVC電工套管沒有帶電危險(xiǎn)。2.抗沖擊能力強(qiáng)：PVC電工套管能承受壓力，可暗敷于混凝土內(nèi)，不怕受壓、沖擊的破壞。3.防火性能好：PVC電工套管氧指標(biāo)高，具有難燃性，離開火焰瞬間自熄滅。4.防潮、耐酸堿：PVC電工套管防潮不會(huì)象金屬套管產(chǎn)生銹蝕，且耐酸、耐堿、耐油。5.防蟲鼠：PVC電工套管不會(huì)發(fā)出蟲鼠喜歡的氣味，可避免蟲鼠啃咬破壞。6.易彎曲：管內(nèi)只須插入一根彈簧,無需加熱用手輕輕用力,即可進(jìn)行彎曲。7.連接方式：用膠粘劑，直接將管與各種配件進(jìn)行連接,便可完成各種布線要求。單一電線護(hù)套管用非磁性材料以減少發(fā)熱。四川多聯(lián)pvc電線套管規(guī)格</p><p style="text-indent:25px">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。成都日豐pvc電線套管批發(fā)</p><p> 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。成都日豐pvc電線套管批發(fā)</p></p><br
