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。但不少人認為，pvc電線作為一種絕緣電線，表面已經(jīng)有了保護層，是不需要格外套管的。那pvc線纜到底還要不要套管呢？其實，無論是pvc電線還是其他類型的電線，對其進行套管是十分有必要的，四川聯(lián)塑pvc電線套管價格。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，四川聯(lián)塑pvc電線套管價格，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，四川聯(lián)塑pvc電線套管價格、絕緣性好，價格優(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。復合電線護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。四川聯(lián)塑pvc電線套管價格</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="四川聯(lián)塑pvc電線套管價格,pvc電線套管" src="https://tyunfile.71360.com/UploadFile/sccsjjc/637233438797558594/4089660.jpg"></div><p> 三、PVC材質(zhì)電線管電路施工注意事項1.電線管不得破損、有毛刺。2.如走暗線，開槽的深度及寬度≥電線管的。3.開槽時不得割斷鋼筋。4.如需要做防水，應(yīng)先做防水。5.電管線管內(nèi)電線應(yīng)分色，不得破損，扭結(jié)。6.線管應(yīng)固定，間距不大于800毫米。7.線管與暗盒連接應(yīng)用鎖扣。8.線管之間連接應(yīng)用直接，并且用**膠水。9.線管內(nèi)的電線截面積之和不大于線管截面積的40%。10.強弱電插座間距不大500毫米。11.強弱電管交叉時，應(yīng)做屏蔽保護。12.電線管與水管及燃氣管同一平面時間距≥100毫米，不同平面時間距≥50毫米。13.電器插座與燃氣管間距≥150毫米。14.線管內(nèi)電線應(yīng)能抽動。15.電線管不得走直角彎或死彎。應(yīng)走月亮彎。四川聯(lián)塑pvc電線套管價格電工套管和電線套管的區(qū)別？</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="四川聯(lián)塑pvc電線套管價格,pvc電線套管"

電線埋墻必需穿線管，一般可選的PVC穿線管/PE穿線管：價格實惠，可彎曲，絕緣性能好。其實一般家庭選擇PVC穿線管/PE穿線管就非常不錯了，只是要選擇結(jié)實的，簡單方法就是用腳踩一下，不會被踩癟的就是好的。然后提醒一下：無論使用哪種穿線管，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，也難保以后會出現(xiàn)故障，需要更換線路，這個時候，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法拽動的“死線”：1、當然**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”，不能無故繞線，這樣不但會造成死線，還會增大電改投入。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。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。

墻體及地面用無齒鋸開槽完畢后，布下穿線管，線徑不低于16毫米阻燃管及“86”線盒，然后進行線管內(nèi)穿線(配線時，相線與零線的顏**別分開，同一住宅相線(L)顏色應(yīng)統(tǒng)一，零線(W)宜用藍色，保護線(PE)宜用黃綠雙色線)。其次，電源線管暗埋時，應(yīng)考慮與弱電管線等保持500毫米以上距離，電線管與熱水管、煤氣管之間平行距離不小于300毫米，強弱電禁止同管施工，干擾弱電信號。第三，線與線的盒內(nèi)連接彩用U型纏繞6圈半國標技術(shù)，以防導致電線連接不緊密產(chǎn)生“打火”。下線盒5分線盒內(nèi)的電線接頭處，應(yīng)做“掛錫”處理，防止電線氧化產(chǎn)生短路現(xiàn)象，穿線管并纏繞防水膠帶和高壓絕緣膠帶。在穿完線以后要用絕緣膠帶和防水膠帶對電源導線接頭進行雙層絕緣。電容式電線護套管由電容心子、瓷套、金屬附件和導體構(gòu)成。</p><div

為了保護電纜，電纜敷設(shè)時在易受外力損傷的部位要加裝保護管。通常使用的保護管有鋼管和硬質(zhì)塑料管。保護管的內(nèi)徑不應(yīng)小于電纜外徑的。管壁厚度不小7afe4b893e5b19e239于2mm。硬質(zhì)塑料管不能用在溫度過高和過低的場所。通過基礎(chǔ)（包括地面或樓板）的保護管，內(nèi)徑在32mm及以下時，用鋼管保護。電力電纜一般在下列場所加裝保護管：（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高的一段和易受機械損傷的其他部位。一、電線管套作用
