電(dian)(dian)(dian)(dian)伴熱(re)帶(dai)(dai)根據結(jie)構的(de)(de)(de)不(bu)(bu)同(tong)，有(you)(you)著不(bu)(bu)同(tong)的(de)(de)(de)分類(lei)，不(bu)(bu)同(tong)的(de)(de)(de)電(dian)(dian)(dian)(dian)伴熱(re)帶(dai)(dai)有(you)(you)著自(zi)身的(de)(de)(de)特(te)性和適用的(de)(de)(de)區域(yu)。電(dian)(dian)(dian)(dian)伴熱(re)帶(dai)(dai)雖然都作為(wei)保溫材料(liao)，但不(bu)(bu)同(tong)區域(yu)對電(dian)(dian)(dian)(dian)伴熱(re)帶(dai)(dai)的(de)(de)(de)要求不(bu)(bu)同(tong)，這(zhe)也是(shi)電(dian)(dian)(dian)(dian)伴熱(re)帶(dai)(dai)有(you)(you)很多分類(lei)的(de)(de)(de)原因所在。具體有(you)(you)哪些分類(lei)，接(jie)著來看。

　　根據高分子PTC材料的組成不同，自控溫加熱電纜分為低(di)溫型和高溫型兩類(lei)。

　　市場上(shang)常(chang)見的(de)(de)有(you)以(yi)(yi)聚烯(xi)烴為(wei)基材(cai)的(de)(de)65℃溫(wen)(wen)(wen)度(du)(du)等(deng)級(ji)的(de)(de)加(jia)熱(re)電(dian)(dian)(dian)纜(lan)和(he)以(yi)(yi)含氟材(cai)料為(wei)基材(cai)的(de)(de)110℃和(he)150℃加(jia)熱(re)電(dian)(dian)(dian)纜(lan)。此(ci)處的(de)(de)溫(wen)(wen)(wen)度(du)(du)等(deng)級(ji)定(ding)義為(wei)加(jia)熱(re)電(dian)(dian)(dian)纜(lan)所能有(you)效(xiao)應(ying)(ying)用(yong)的(de)(de)高環境溫(wen)(wen)(wen)度(du)(du)。也可(ke)以(yi)(yi)理解為(wei)電(dian)(dian)(dian)纜(lan)能夠長(chang)期穩定(ding)應(ying)(ying)用(yong)并產生(sheng)有(you)效(xiao)加(jia)熱(re)功(gong)率(lv)輸出的(de)(de)高環境溫(wen)(wen)(wen)度(du)(du)，超(chao)(chao)過(guo)規定(ding)溫(wen)(wen)(wen)度(du)(du)等(deng)級(ji)，一方面由(you)于電(dian)(dian)(dian)阻，電(dian)(dian)(dian)纜(lan)本身(shen)的(de)(de)輸出功(gong)率(lv)很小(xiao)，實際加(jia)熱(re)效(xiao)率(lv)很低。另(ling)一方面，長(chang)期的(de)(de)超(chao)(chao)溫(wen)(wen)(wen)使(shi)用(yong)，使(shi)電(dian)(dian)(dian)纜(lan)性(xing)(xing)能如：PTC特性(xing)(xing)，加(jia)熱(re)功(gong)率(lv)等(deng)劣化或(huo)衰減，會降低電(dian)(dian)(dian)纜(lan)的(de)(de)使(shi)用(yong)壽(shou)命和(he)運(yun)行(xing)可(ke)靠性(xing)(xing)。但短期間斷(duan)地暴露于超(chao)(chao)過(guo)溫(wen)(wen)(wen)度(du)(du)等(deng)極(ji)的(de)(de)溫(wen)(wen)(wen)度(du)(du)環境，也是可(ke)以(yi)(yi)的(de)(de)。因此(ci)，除上(shang)述溫(wen)(wen)(wen)度(du)(du)等(deng)級(ji)外，自(zi)控溫(wen)(wen)(wen)加(jia)熱(re)電(dian)(dian)(dian)線，還有(you)另(ling)一個溫(wen)(wen)(wen)度(du)(du)等(deng)級(ji)。如對于65℃溫(wen)(wen)(wen)度(du)(du)等(deng)級(ji)的(de)(de)電(dian)(dian)(dian)纜(lan)，該溫(wen)(wen)(wen)度(du)(du)等(deng)級(ji)為(wei)85℃，對于110℃溫(wen)(wen)(wen)度(du)(du)等(deng)級(ji)的(de)(de)電(dian)(dian)(dian)纜(lan)，為(wei)130℃，而對于150℃電(dian)(dian)(dian)纜(lan)，則(ze)為(wei)230℃。然而此(ci)時(shi)的(de)(de)電(dian)(dian)(dian)纜(lan)有(you)效(xiao)輸出功(gong)率(lv)已接近于零。

電(dian)(dian)(dian)伴(ban)(ban)熱(re)(re)(re)(re)(re)(re)是指為了貯藏或(huo)運輸(shu)(shu)的目的向(xiang)容器(qi)內(nei)（管道、 容器(qi)或(huo)設(she)備內(nei)）或(huo)者向(xiang)產品（液態、粉(fen)狀或(huo)氣體）供熱(re)(re)(re)(re)(re)(re)以避免傳(chuan)輸(shu)(shu)問題(ti)或(huo)困(kun)難。電(dian)(dian)(dian)伴(ban)(ban)熱(re)(re)(re)(re)(re)(re)產品主要(yao)可以分為自(zi)(zi)限(xian)溫(wen)(wen)(wen)電(dian)(dian)(dian)伴(ban)(ban)熱(re)(re)(re)(re)(re)(re)帶(dai)(dai)和恒(heng)功(gong)率電(dian)(dian)(dian)伴(ban)(ban)熱(re)(re)(re)(re)(re)(re)帶(dai)(dai)兩個系列，自(zi)(zi)限(xian)溫(wen)(wen)(wen)電(dian)(dian)(dian)伴(ban)(ban)熱(re)(re)(re)(re)(re)(re)帶(dai)(dai)可以實現自(zi)(zi)動(dong)控溫(wen)(wen)(wen)，而恒(heng)功(gong)率電(dian)(dian)(dian)伴(ban)(ban)熱(re)(re)(re)(re)(re)(re)帶(dai)(dai)實現不了。       恒(heng)功(gong)率電(dian)(dian)(dian)伴(ban)(ban)熱(re)(re)(re)(re)(re)(re)帶(dai)(dai)單(dan)位長度的發熱(re)(re)(re)(re)(re)(re)量輸(shu)(shu)出是恒(heng)定的，它的輸(shu)(shu)出功(gong)率不會隨著外界(jie)環境(jing)、保溫(wen)(wen)(wen)材(cai)料以及伴(ban)(ban)熱(re)(re)(re)(re)(re)(re)材(cai)質的變化而變化，所以在使用(yong)時需要(yao)配套溫(wen)(wen)(wen)度控制器(qi)、控制箱。當(dang)伴(ban)(ban)熱(re)(re)(re)(re)(re)(re)和耐溫(wen)(wen)(wen)溫(wen)(wen)(wen)度要(yao)求過高的時候自(zi)(zi)限(xian)溫(wen)(wen)(wen)電(dian)(dian)(dian)伴(ban)(ban)熱(re)(re)(re)(re)(re)(re)帶(dai)(dai)不符(fu)合要(yao)求，就可以選擇(ze)恒(heng)功(gong)率電(dian)(dian)(dian)伴(ban)(ban)熱(re)(re)(re)(re)(re)(re)帶(dai)(dai)。

防爆電伴(ban)熱帶技術廣泛(fan)應用于各個領域

比如工業領域使用的自限溫電伴熱帶（或自控溫電伴熱帶），這款電伴熱帶的設計是比較人性化的。自限溫電伴熱帶按照溫度分為三個等級，分別是低溫自限溫電伴熱帶、中溫自限溫電伴熱帶和高溫自限溫電伴熱帶。其中低溫自限溫電伴熱帶 高工作溫度為65℃左右，中溫自限溫電伴熱帶 高工作溫度為105℃左右，而高溫自限溫電伴熱帶 高工作溫度為130℃左右，可以根據使用場所來選擇不同的自限溫電伴熱帶。從字面的意思就可以理解自限溫電伴熱帶無需任何溫控器類別的附件來控溫，自控溫電伴熱帶自身溫度達到或略高于 高工作溫度時，則自控切斷電源停止伴熱。當自控溫電伴熱帶自身溫度低于被伴熱溫度時，則自動開啟自控溫電伴熱帶。
