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。四川聯(lián)塑pvc電線套管質(zhì)量穿纜式利用變壓器的引出電纜直接穿過套管,安裝方便。</p><div

此外，注意PVC電線管施工時(shí)，避免因剔鑿造成的墻面裂縫及墻體結(jié)構(gòu)破壞，鋪設(shè)時(shí)應(yīng)視管內(nèi)導(dǎo)線數(shù)量多少而變化，一管內(nèi)不宜超過四根，建議照明走一路，空調(diào)走一路，插座走三~四路，一旦某線路發(fā)生短路或者其他問題，不會(huì)影響其他幾路的正常運(yùn)行。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。四川耐用性高pvc電線套管批發(fā)</p></p><br
