中溫(wen)防爆電伴(ban)熱帶-旭誠(cheng)(在線咨(zi)詢)

電(dian)伴熱(re)(re)(re)帶(dai)根據結構的不(bu)同(tong)(tong)，有(you)著(zhu)不(bu)同(tong)(tong)的分(fen)類，不(bu)同(tong)(tong)的電(dian)伴熱(re)(re)(re)帶(dai)有(you)著(zhu)自身的特性(xing)和適用的區域(yu)(yu)。電(dian)伴熱(re)(re)(re)帶(dai)雖(sui)然(ran)都作為保溫材(cai)料，但不(bu)同(tong)(tong)區域(yu)(yu)對電(dian)伴熱(re)(re)(re)帶(dai)的要(yao)求不(bu)同(tong)(tong)，這也是(shi)電(dian)伴熱(re)(re)(re)帶(dai)有(you)很多分(fen)類的原因所在。具(ju)體有(you)哪些(xie)分(fen)類，接著(zhu)來看。

　　根據高分子PTC材料的組成不(bu)同，自(zi)控溫(wen)加熱電纜分為低溫(wen)型(xing)和高溫(wen)型(xing)兩類。

　　市場上(shang)常見(jian)的有(you)(you)以聚烯烴為(wei)基材(cai)的65℃溫(wen)(wen)(wen)(wen)度(du)(du)等(deng)(deng)級(ji)(ji)的加(jia)熱(re)電(dian)(dian)纜(lan)(lan)(lan)(lan)(lan)和(he)以含氟材(cai)料為(wei)基材(cai)的110℃和(he)150℃加(jia)熱(re)電(dian)(dian)纜(lan)(lan)(lan)(lan)(lan)。此(ci)處的溫(wen)(wen)(wen)(wen)度(du)(du)等(deng)(deng)級(ji)(ji)定(ding)(ding)義(yi)為(wei)加(jia)熱(re)電(dian)(dian)纜(lan)(lan)(lan)(lan)(lan)所(suo)能(neng)有(you)(you)效(xiao)(xiao)應(ying)(ying)用(yong)的高環境溫(wen)(wen)(wen)(wen)度(du)(du)。也(ye)(ye)可(ke)以理解為(wei)電(dian)(dian)纜(lan)(lan)(lan)(lan)(lan)能(neng)夠長(chang)期穩定(ding)(ding)應(ying)(ying)用(yong)并產生(sheng)有(you)(you)效(xiao)(xiao)加(jia)熱(re)功(gong)率(lv)(lv)(lv)輸(shu)出(chu)(chu)的高環境溫(wen)(wen)(wen)(wen)度(du)(du)，超過(guo)(guo)規定(ding)(ding)溫(wen)(wen)(wen)(wen)度(du)(du)等(deng)(deng)級(ji)(ji)，一方面(mian)由于(yu)電(dian)(dian)阻(zu)，電(dian)(dian)纜(lan)(lan)(lan)(lan)(lan)本身(shen)的輸(shu)出(chu)(chu)功(gong)率(lv)(lv)(lv)很小(xiao)，實際(ji)加(jia)熱(re)效(xiao)(xiao)率(lv)(lv)(lv)很低。另(ling)一方面(mian)，長(chang)期的超溫(wen)(wen)(wen)(wen)使用(yong)，使電(dian)(dian)纜(lan)(lan)(lan)(lan)(lan)性(xing)(xing)能(neng)如：PTC特性(xing)(xing)，加(jia)熱(re)功(gong)率(lv)(lv)(lv)等(deng)(deng)劣化或衰減(jian)，會降(jiang)低電(dian)(dian)纜(lan)(lan)(lan)(lan)(lan)的使用(yong)壽命和(he)運行可(ke)靠性(xing)(xing)。但(dan)短期間斷地暴(bao)露于(yu)超過(guo)(guo)溫(wen)(wen)(wen)(wen)度(du)(du)等(deng)(deng)極(ji)的溫(wen)(wen)(wen)(wen)度(du)(du)環境，也(ye)(ye)是可(ke)以的。因此(ci)，除上(shang)述溫(wen)(wen)(wen)(wen)度(du)(du)等(deng)(deng)級(ji)(ji)外，自控(kong)溫(wen)(wen)(wen)(wen)加(jia)熱(re)電(dian)(dian)線(xian)，還(huan)有(you)(you)另(ling)一個溫(wen)(wen)(wen)(wen)度(du)(du)等(deng)(deng)級(ji)(ji)。如對于(yu)65℃溫(wen)(wen)(wen)(wen)度(du)(du)等(deng)(deng)級(ji)(ji)的電(dian)(dian)纜(lan)(lan)(lan)(lan)(lan)，該溫(wen)(wen)(wen)(wen)度(du)(du)等(deng)(deng)級(ji)(ji)為(wei)85℃，對于(yu)110℃溫(wen)(wen)(wen)(wen)度(du)(du)等(deng)(deng)級(ji)(ji)的電(dian)(dian)纜(lan)(lan)(lan)(lan)(lan)，為(wei)130℃，而對于(yu)150℃電(dian)(dian)纜(lan)(lan)(lan)(lan)(lan)，則(ze)為(wei)230℃。然而此(ci)時的電(dian)(dian)纜(lan)(lan)(lan)(lan)(lan)有(you)(you)效(xiao)(xiao)輸(shu)出(chu)(chu)功(gong)率(lv)(lv)(lv)已接近于(yu)零。

　　通(tong)用(yong)型(xing)加(jia)熱(re)(re)電(dian)(dian)纜(lan)：是(shi)指由銅導(dao)線，高分(fen)子PTC材料和單層阻燃護(hu)套所組成(cheng)的(de)(de)加(jia)熱(re)(re)電(dian)(dian)纜(lan)。主(zhu)要應用(yong)于一般(ban)場合下的(de)(de)管網的(de)(de)加(jia)熱(re)(re)或伴熱(re)(re)。防爆增(zeng)強型(xing)加(jia)熱(re)(re)電(dian)(dian)纜(lan)：是(shi)在通(tong)用(yong)型(xing)電(dian)(dian)纜(lan)的(de)(de)外層再(zai)復合一層金屬網，這種結構電(dian)(dian)纜(lan)可(ke)有(you)(you)效消(xiao)除靜電(dian)(dian)和抵御外來機械碰境。主(zhu)要應用(yong)于具有(you)(you)防爆要求(qiu)的(de)(de)場所。

　　防腐防爆增(zeng)強型電(dian)(dian)(dian)纜：這(zhe)種結構的電(dian)(dian)(dian)纜是在防爆增(zeng)強型加熱電(dian)(dian)(dian)纜的金(jin)屬網外層，再復合上一層含氟材料。具有這(zhe)種結構的加熱電(dian)(dian)(dian)纜可有效地防止和(he)抵御(yu)靜電(dian)(dian)(dian)，機械碰撞和(he)各種腐蝕性介(jie)質。主要應用于環境惡劣或有物品的場所。

伴熱(re)帶(dai)中銅(tong)芯導(dao)線的(de)作用 1、避免電伴熱(re)帶(dai)內(nei)發熱(re)芯的(de)氧(yang)化； 2、鍍錫能(neng)(neng)避免銅(tong)暴(bao)露在(zai)空氣中而被氧(yang)化構成一層膜（銅(tong)綠(lv)）。而銅(tong)綠(lv)的(de)導(dao)電性很差會添(tian)加電阻阻值； 3、伴熱(re)帶(dai)的(de)內(nei)部導(dao)線具有很好的(de)抗腐蝕功能(neng)(neng)，又有強(qiang)度(du)和硬度(du)，成型(xing)性好又易焊(han)接。 4、同時也具有抵抗高溫(wen)(wen)的(de)效果，可運用溫(wen)(wen)度(du)范圍在(zai)一百(bai)攝(she)氏溫(wen)(wen)度(du)以內(nei)的(de)這些高溫(wen)(wen)環境中。
