而提到套管，電線管的選擇則不可避免。目前常見(jiàn)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。然后，在選購(gòu)電線管時(shí)，除了確定好類型外，也要注意一些分辨電線管質(zhì)量的小技巧。比如拿到一個(gè)線管，先看產(chǎn)品上的標(biāo)志（生產(chǎn)商名稱、廠址、型號(hào)、規(guī)格等）是否和合格證上的一致；然后看線管外觀是否完整，如果有破損、刮痕、氣泡、污漬等現(xiàn)象，慎重購(gòu)買(mǎi)。成都多聯(lián)塑膠pvc電線套管這種瓷套管的瓷套內(nèi)壁涂半導(dǎo)體釉，并用彈簧片與導(dǎo)體接通使空氣腔短路，用以消除內(nèi)部電暈。</p><div

第二點(diǎn)，正確進(jìn)行施工安裝PVC電力管的生產(chǎn)廠家一般標(biāo)配有直接、彎頭、三通等配件，在施工時(shí)如遇長(zhǎng)度不夠應(yīng)用直接進(jìn)行連接。有些工人為了省事往往不用彎頭、直接頭，采用手工掰彎或2根管子直接聯(lián)穿，都會(huì)一定程度影響穿管效果;管子末端到開(kāi)關(guān)底盒處，應(yīng)當(dāng)穿進(jìn)底盒。有些工人先裁料后穿管，管子末端未能穿進(jìn)底盒，而相差一截，此處末端和中間一樣，不允許有線材暴露在管外受水泥侵蝕，必須要求管件穿進(jìn)開(kāi)關(guān)底盒;遇有彎曲時(shí)，標(biāo)準(zhǔn)角度(如90)可用彎頭進(jìn)行連接，也可以用彈簧將線管彎曲成任意角度。

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。空氣腔套管用于10千伏及以下電壓等級(jí)，導(dǎo)體與瓷套之間有空氣腔作為輔助絕緣。</p><div

PVC穿線管主要成份為聚氯乙烯，加入其他成分來(lái)增強(qiáng)其耐熱性、韌性、延展性的一種材料。PVC可分為軟PVC和硬PVC。其中硬PVC大約占市場(chǎng)的2/3，軟PVC占1/3。軟PVC一般用于地板、天花板以及皮革的表層，但由于軟PVC中含有增塑劑（這也是軟PVC與硬PVC的區(qū)別），物理性能較差（如上水管需要承受一定水壓，軟質(zhì)PVC就不適合使用），所以其使用范圍受到了局限。硬PVC不含增塑劑，因此易成型，物理性能佳，因此具有很大的開(kāi)發(fā)應(yīng)用價(jià)值。聚氯乙烯材料生產(chǎn)過(guò)程中，勢(shì)必添加幾種助劑，如穩(wěn)定劑，增塑劑等等，倘若全部采用環(huán)保助劑。根據(jù)材質(zhì)性能可分四類：?jiǎn)我浑娋€護(hù)套管、復(fù)合電線護(hù)套管、電容式電線護(hù)套管和不銹鋼護(hù)套管。成都多聯(lián)塑膠pvc電線套管</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(guò)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(guò)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。四川耐用性高pvc電線套管供應(yīng)商</p><p
