電纜保護套管是電力工程中推廣使用的一種新型套管材料。隨著電力電纜埋地敷設(shè)工程的迅速發(fā)展，對電纜套管提出的更高要求，電纜保護套管是采用聚乙烯PE和質(zhì)量鋼管經(jīng)過噴砂拋丸前處理、浸塑或涂裝、加溫固化工藝制作而成。它是保護電線和電纜**常用的一種電絕緣管。因為具有絕緣性能良好、化學(xué)穩(wěn)定性高、不生銹、不老化、可適應(yīng)苛刻環(huán)境而被大面積得以應(yīng)用。1、耐腐蝕，使用壽命長，可在潮濕鹽堿地帶使用。2、阻燃、耐熱性好，可在130度高溫下長期使用而不變形，遇火不燃燒。3、強度高、剛度高。用在行車道下直埋無需加混凝土保護層，能輥快電纜工程建設(shè)進度。4、管材有柔性，能抵御外界重壓和基礎(chǔ)沉降所引起的破壞。5、具有良好的抗外界信號干擾性能。6、內(nèi)壁光滑，不刮傷電纜。設(shè)計采用承插式的連接方式，方便安裝連接。接頭處加橡膠密封圈封既適應(yīng)熱脹冷縮，又防止泥砂進入。四川聯(lián)塑pvc電線套管規(guī)格單一電線護套管用非磁性材料以減少發(fā)熱。</p><div

PVC可分為軟PVC和硬PVC。其中硬PVC大約占市場的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，因此具有很大的開發(fā)應(yīng)用價值。聚氯乙烯材料生產(chǎn)過程中，勢必添加幾種助劑，如穩(wěn)定劑，增塑劑等等，倘若全部采用環(huán)保助劑；具有優(yōu)良的力學(xué)性能。具有抗彎曲疲勞性。熱性能：具有良好的耐熱性，能在100℃以上溫度進行消毒滅菌，在不受外力的條件下，150℃也不變形。脆化溫度為-35℃，在低于-35℃會發(fā)生脆化?；瘜W(xué)穩(wěn)定性：化學(xué)穩(wěn)定性很好，除能被濃、濃硝酸侵蝕外，對其它各種化學(xué)試劑都比較穩(wěn)定，防腐蝕效果良好。電性能：高頻絕緣性能優(yōu)良，由于它幾乎不吸水，故絕緣性能不受濕度的影響。 </p><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。根據(jù)材質(zhì)性能可分四類：單一電線護套管、復(fù)合電線護套管、電容式電線護套管和不銹鋼護套管。</p><div

安裝注意事項：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，直角死彎往往會造成死線。搬、運要比金屬鋼管和水泥管輕松、方便。施工安裝簡便，既省事又省力。成都多聯(lián)pvc電線套管價格</p><p
