　電(dian)伴熱(re)(re)帶(dai)含(han)義及(ji)作(zuo)用介(jie)紹，自(zi)限(xian)溫(wen)電(dian)伴熱(re)(re)帶(dai)也是帶(dai)狀限(xian)溫(wen)電(dian)加熱(re)(re)器(qi)，其發熱(re)(re)材料的電(dian)阻率具有很高(gao)(gao)的正溫(wen)度系數(PTC)。在二根平行的金屬(shu)線芯(xin)之(zhi)間均勻地擠塑半導電(dian)的高(gao)(gao)分子復合PTC材料，在其外面(mian)再包一(yi)層絕緣材料作(zuo)為護(hu)套，便得(de)到可(ke)以使(shi)用的基本型電(dian)伴熱(re)(re)帶(dai)，如有必要也可(ke)再加屏蔽及(ji)防護(hu)層。

　　電(dian)伴熱(re)帶(dai)含義及作(zuo)用介紹(shao)，并(bing)(bing)聯恒功率電(dian)伴熱(re)帶(dai)電(dian)源(yuan)母線為二根平行絕緣(yuan)銅線，在(zai)內絕緣(yuan)層上纏繞電(dian)熱(re)絲，并(bing)(bing)將電(dian)熱(re)絲每隔(ge)一定距離(即“發(fa)熱(re)節長”)與母線連接，形(xing)成連續并(bing)(bing)聯電(dian)阻(zu)(zu)。母線通電(dian)后，各(ge)并(bing)(bing)聯電(dian)阻(zu)(zu)發(fa)熱(re)，因而形(xing)成一條連續的加熱(re)電(dian)纜。

怎么樣選(xuan)擇合適的(de)電(dian)伴(ban)熱(re)(re)(re)帶(dai)(dai)型(xing)(xing)號？ 電(dian)伴(ban)熱(re)(re)(re)主要分為兩大類(lei)產品(pin)(pin)自(zi)限溫(wen)和(he)恒(heng)功(gong)(gong)(gong)率(lv)(lv)，另(ling)外電(dian)伴(ban)熱(re)(re)(re)還包(bao)含MI加熱(re)(re)(re)電(dian)纜和(he)伴(ban)熱(re)(re)(re)采樣復合管等(deng)產品(pin)(pin)，其中(zhong)自(zi)限溫(wen)又分為低溫(wen)和(he)中(zhong)溫(wen)型(xing)(xing)自(zi)限溫(wen)電(dian)伴(ban)熱(re)(re)(re)帶(dai)(dai)，而(er)恒(heng)功(gong)(gong)(gong)率(lv)(lv)產品(pin)(pin)又可分為串(chuan)聯和(he)并聯恒(heng)功(gong)(gong)(gong)率(lv)(lv)兩大類(lei)，自(zi)限溫(wen)電(dian)伴(ban)熱(re)(re)(re)帶(dai)(dai)一般使(shi)(shi)用(yong)距離不超(chao)過百米，并聯恒(heng)功(gong)(gong)(gong)率(lv)(lv)的(de)使(shi)(shi)用(yong)長度(du)(du)在800米之內，串(chuan)聯恒(heng)功(gong)(gong)(gong)率(lv)(lv)的(de)使(shi)(shi)用(yong)長度(du)(du)一般在500-2500米之間。另(ling)外在安(an)裝使(shi)(shi)用(yong)過程中(zhong)自(zi)限溫(wen)電(dian)伴(ban)熱(re)(re)(re)帶(dai)(dai)是可以(yi)隨意剪切的(de)，而(er)串(chuan)聯恒(heng)功(gong)(gong)(gong)率(lv)(lv)和(he)MI加熱(re)(re)(re)電(dian)纜是不能剪切的(de)。
