PVC電線管、A管和B管有什么區(qū)別？?jī)烧邊^(qū)別如下：1、A管相對(duì)B管用料要好些，強(qiáng)度高點(diǎn)copy，厚度也厚一點(diǎn)。2、A管相對(duì)B管，價(jià)格更高一些。3、A管通常用作排水，B管通常用作通風(fēng)。管材優(yōu)點(diǎn)1、具有較好的抗拉、抗壓強(qiáng)度：但其柔性不如其他塑料管。2、流體阻力?。篜VC-U管材的管壁非常光滑，對(duì)流體的阻力很小，其粗糙系數(shù)*為，其輸水能力可比同等管徑的鑄百鐵管提高20%，比混凝土管提高40%。3、耐腐蝕性、耐藥品性優(yōu)良：PVC-U管材具有優(yōu)異的耐酸，耐堿，耐腐蝕，不受潮濕水份和土壤酸堿度的影響，管道鋪設(shè)時(shí)不需任何防腐處理度。4、具有良好的水密性：PVC-U管材的安裝，不論采用粘接還是橡膠圈連接，均具有良好的水密性。 </p><p> 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(méi)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(kāi)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(chóng)鼠：PVC電工套管不會(huì)發(fā)出蟲(chóng)鼠喜歡的氣味，可避免蟲(chóng)鼠啃咬破壞。6.易彎曲：管內(nèi)只須插入一根彈簧,無(wú)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。穿纜式利用變壓器的引出電纜直接穿過(guò)套管,安裝方便。</p><div

電線埋墻必需穿線管，一般可選的PVC穿線管/PE穿線管：價(jià)格實(shí)惠，可彎曲，絕緣性能好。其實(shí)一般家庭選擇PVC穿線管/PE穿線管就非常不錯(cuò)了，只是要選擇結(jié)實(shí)的，簡(jiǎn)單方法就是用腳踩一下，不會(huì)被踩癟的就是好的。然后提醒一下：無(wú)論使用哪種穿線管，電線在管內(nèi)都不能有接頭。電路改造應(yīng)避免死線：再好的電路質(zhì)量，也難保以后會(huì)出現(xiàn)故障，需要更換線路，這個(gè)時(shí)候，埋墻的電線能夠方便的拽出更換就顯得非常重要，所以在電改施工中要避免造成日后無(wú)法拽動(dòng)的“死線”：1、當(dāng)然**重要的是要使用穿線管埋線。2、電路走線應(yīng)該把握“兩端間**近距離走線”，不能無(wú)故繞線，這樣不但會(huì)造成死線，還會(huì)增大電改投入。3、一根穿線管中不要穿太多線，穿線后都應(yīng)該拽一下，看看是否可以輕松拽動(dòng)。4、線路有接頭必需在接頭處留暗盒扣面板，日后更換和維修都方便。5、管徑小于25的PVC穿線管拐彎應(yīng)用彎管器，不能加彎頭拐彎。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)。成都多聯(lián)pvc電線套管型號(hào)</p><p
