由于冬季氣溫比較低，像油管線，油罐的罐體、水管線、油井井口工藝、化工生產管道等如果沒有保溫將會出現凍堵現象影響正常的使用，因此需要安裝電伴熱帶防凍保溫。而在安裝過程中由于工作人員的操作不規范，安裝不正確，影響使用。那么有哪些電伴熱帶不正確的安裝形式呢？

  1.不(bu)使(shi)用(yong)專用(yong)接線盒(he)，電伴熱帶(dai)與導線連接處(chu)不(bu)用(yong)接線盒(he)連接。

  2.不(bu)使用(yong)專用(yong)封(feng)(feng)頭(tou)安裝電(dian)伴熱(re)帶；電(dian)伴熱(re)帶的封(feng)(feng)頭(tou)用(yong)絕緣膠布纏繞而(er)不(bu)用(yong)專用(yong)封(feng)(feng)頭(tou)，這樣(yang)如果封(feng)(feng)頭(tou)內進(jin)水后就會造成故障。

  3.電(dian)(dian)源(yuan)安裝(zhuang)不正(zheng)確；在(zai)安裝(zhuang)電(dian)(dian)伴熱帶導線時，不安裝(zhuang)電(dian)(dian)伴熱帶專用開(kai)關(guan)而經常把導線直接(jie)安裝(zhuang)在(zai)空氣開(kai)關(guan)上(shang)端，這樣安裝(zhuang)使開(kai)關(guan)電(dian)(dian)路無(wu)法對電(dian)(dian)路起到保(bao)護作用。

  4.用鐵(tie)(tie)(tie)絲綁扎電伴(ban)熱帶，由于電伴(ban)熱帶的絕緣層是聚乙烯(xi)材料，所以鐵(tie)(tie)(tie)絲綁扎后(hou)電伴(ban)熱帶加熱后(hou)會造(zao)成聚乙烯(xi)層被鐵(tie)(tie)(tie)絲勒進去而造(zao)成短路。

  5.纏繞不規范(fan)；電(dian)(dian)伴熱(re)(re)帶任意纏繞間距隨(sui)意，導致(zhi)電(dian)(dian)伴熱(re)(re)帶在管壁上發熱(re)(re)不均勻。

  6.電伴(ban)熱(re)帶與電源(yuan)連(lian)接線(xian)使用風雨線(xian)連(lian)接并且(qie)直(zhi)埋在地下；電伴(ban)熱(re)帶應(ying)采用鎧(kai)裝電纜(lan)直(zhi)埋安裝，如果用風雨線(xian)連(lian)接，冰(bing)雪融化會造成漏電和短路。

  7.控制(zhi)電(dian)(dian)(dian)(dian)源不(bu)使用(yong)漏電(dian)(dian)(dian)(dian)保護器，當電(dian)(dian)(dian)(dian)路發(fa)生(sheng)漏電(dian)(dian)(dian)(dian)或電(dian)(dian)(dian)(dian)流過大時，開關不(bu)跳閘，造成三相電(dian)(dian)(dian)(dian)壓(ya)嚴重不(bu)平衡，使同一回路的電(dian)(dian)(dian)(dian)機和供(gong)電(dian)(dian)(dian)(dian)變壓(ya)器不(bu)能正常工作。
