PVC管的主要成份為聚百氯乙烯； PC管的主要成分為聚碳酸酯。四川口碑好pvc電線套管代理商</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="四川口碑好pvc電線套管代理商,pvc電線套管"

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。成都耐用性高pvc電線套管供應(yīng)商可以減少套管電容，提高套管的電暈電壓和滑閃電壓。當(dāng)電壓等級較高時。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="四川口碑好pvc電線套管代理商,pvc電線套管" src="https://tyunfile.71360.com/UploadFile/sccsjjc/637233438800126953/221404.jpg"></div><p> 第三點，管線彎曲時應(yīng)注意彎曲應(yīng)慢慢進行，否則易損壞管子及其彎曲彈簧;彎管彈簧未取出之前，不要用力使變管回復(fù)以防損壞彈簧;彎管彈簧不易取出時，可一邊逆時針旋轉(zhuǎn)彈簧，一邊向外拉出彈簧;當(dāng)管子較長時，可在彈簧上系上繩子;寒冷天氣施工時，可將管子彎曲處摩擦適當(dāng)升溫后進行。電氣線路的穿管保護作用在于防止電氣線路的絕緣層不受高溫、潮濕或腐蝕等作用的影響而失去絕緣能力，避免絕緣層陳舊老化或受損致使線芯裸露，同時PVC電力管可以隔離電線電纜與可燃物接觸，控制火災(zāi)蔓延。 </p><p> 二、PVC電線管特性：PVC電線管（亞馬遜塑業(yè)）按型號分輕、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。2.抗沖擊能力強：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,即可進行彎曲。7.連接方式：用膠粘劑，直接將管與各種配件進行連接,便可完成各種布線要求。不銹鋼護套管不銹鋼護套管，材質(zhì)為304不銹鋼或301不銹鋼。</p><div

電容式電線護套管：由電容心子、瓷套、金屬附件和導(dǎo)體構(gòu)成。電容式電線護套管的電容心子用膠紙制造時，機械強度高，可以任何角度安裝,抗潮氣性能好，結(jié)構(gòu)和維修簡單,可不用下套管，還可將心子下端車削成短尾式，縮小其尺寸。缺點是在高電壓等級時，絕級材料和工藝要求較高，心子中不易消除氣隙，以致造成局部放電電壓低。不銹鋼護套管；不銹鋼護套管，材質(zhì)為304不銹鋼或301不銹鋼，用作電線、電纜、自動化儀表信號的電線電纜保護管，規(guī)格從3mm到150mm。超小口徑不銹鋼護套管（內(nèi)徑3mm-25mm）主要用于精密光學(xué)尺之傳感線路保護、工業(yè)傳感器線路保護，具有良好的柔軟性、耐蝕性、耐高溫、耐磨損、抗拉性。當(dāng)工作電流大于600安時，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)。成都口碑好pvc電線套管廠家直銷</p><p

第二點，正確進行施工安裝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，在施工時如遇長度不夠應(yīng)用直接進行連接。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，都會一定程度影響穿管效果;管子末端到開關(guān)底盒處，應(yīng)當(dāng)穿進底盒。有些工人先裁料后穿管，管子末端未能穿進底盒，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，必須要求管件穿進開關(guān)底盒;遇有彎曲時，標(biāo)準(zhǔn)角度(如90)可用彎頭進行連接，也可以用彈簧將線管彎曲成任意角度。四川口碑好pvc電線套管代理商</p><p
