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。

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。施工安裝簡(jiǎn)便，既省事又省力。耐腐蝕性能強(qiáng)、絕緣、非磁性、耐酸、耐堿、阻燃型、抗靜電。成都塑膠pvc電線套管一級(jí)經(jīng)銷商</p><p

復(fù)合電線護(hù)套管以油或氣體作絕緣介質(zhì)，一般制成變壓器套管或斷路器套管，常用于35千伏以下的電壓等級(jí)。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。當(dāng)電壓超過35千伏時(shí)，在導(dǎo)體上套以絕緣管或包電纜線，以加強(qiáng)絕緣。復(fù)合電線護(hù)套管的導(dǎo)體結(jié)構(gòu)有穿纜式和導(dǎo)桿式兩種。穿纜式利用變壓器的引出電纜直接穿過套管,安裝方便。當(dāng)工作電流大于600安時(shí)，穿纜式結(jié)構(gòu)安裝比較困難，一般采用導(dǎo)桿式結(jié)構(gòu)。電容式電線護(hù)套管由電容心子、瓷套、金屬附件和導(dǎo)體構(gòu)成。四川川路塑膠pvc電線套管價(jià)格</p></p><br
