電伴熱制(zhi)作(zuo)(zuo)工藝(yi)十分復(fu)雜，需經過(guo)多次復(fu)合(he)后(hou)，才能(neng)形成一條扁平、光滑(hua)的加熱體。這不僅體積小(xiao)，不占太多使用(yong)空間(jian)，而且能(neng)很好的貼合(he)于(yu)管道外壁，有(you)利于(yu)熱量的傳遞工作(zuo)(zuo)。通電后(hou)，通過(guo)電能(neng)產生的熱量，對管道進行熱量補充(chong)，使其溫度(du)勻速上升，并利用(yong)自身PTC特(te)性，控制(zhi)溫度(du)始(shi)終(zhong)保持在合(he)理(li)范圍內，十分安全可(ke)靠。
電(dian)(dian)伴(ban)熱(re)應用(yong)(yong)(yong)(yong)(yong)哪些領(ling)域呢，電(dian)(dian)伴(ban)熱(re)具有(you)熱(re)效(xiao)率高，節約能(neng)源，設計簡(jian)單，施(shi)工(gong)安裝方便，無污染，使(shi)用(yong)(yong)(yong)(yong)(yong)壽命長(chang)，能(neng)實現遙(yao)控(kong)(kong)和自動控(kong)(kong)制等(deng)特點(dian)，可(ke)用(yong)(yong)(yong)(yong)(yong)于加(jia)熱(re)、保(bao)溫(wen)、防(fang)凍(dong)場(chang)所(suo)產(chan)品和工(gong)藝;在農業上用(yong)(yong)(yong)(yong)(yong)于大棚育苗種子(zi)催芽、食(shi)用(yong)(yong)(yong)(yong)(yong)菌(jun)育種、食(shi)品發酵、養殖孵化等(deng)場(chang)所(suo);工(gong)業上可(ke)用(yong)(yong)(yong)(yong)(yong)于石油、天然氣(qi)、水管道加(jia)熱(re)保(bao)溫(wen);交通上用(yong)(yong)(yong)(yong)(yong)于輔設在機(ji)場(chang)跑道、陡坡公路防(fang)止(zhi)結冰打(da)滑、車輛(liang)低(di)溫(wen)啟動;民用(yong)(yong)(yong)(yong)(yong)上可(ke)用(yong)(yong)(yong)(yong)(yong)于恒溫(wen)電(dian)(dian)熱(re)毯、紅外線理療、冬季輸液加(jia)熱(re)等(deng)領(ling)域。
電伴(ban)熱帶(dai)(dai)(dai)產品(pin)通(tong)常(chang)除了溫(wen)(wen)度、屏蔽、防爆(bao)防腐等(deng)進行區(qu)分以外，通(tong)常(chang)歸類為自(zi)限(xian)溫(wen)(wen)電伴(ban)熱帶(dai)(dai)(dai)及恒功(gong)率電伴(ban)熱帶(dai)(dai)(dai)兩大(da)(da)(da)類，自(zi)限(xian)溫(wen)(wen)有(you)(you)其(qi)特有(you)(you)的PTC效應(ying)，施工過程中無需安裝溫(wen)(wen)控器(qi)就能完(wan)成智能調溫(wen)(wen)的特性，而恒功(gong)率電伴(ban)熱帶(dai)(dai)(dai)則咋溫(wen)(wen)度范圍上有(you)(you)更大(da)(da)(da)的發(fa)熱能力，兩者各(ge)有(you)(you)千秋，大(da)(da)(da)家可(ke)以自(zi)行選擇，一(yi)般來(lai)講，在(zai)溫(wen)(wen)度范圍不是很高的情況下，建議選用自(zi)限(xian)溫(wen)(wen)電伴(ban)熱帶(dai)(dai)(dai)。
