恒溫伴熱(re)(re)電纜在主絕緣層(ceng)表面上(shang)纏(chan)繞電熱(re)(re)絲，并(bing)(bing)將該電熱(re)(re)絲每(mei)隔一定距(ju)離（即發熱(re)(re)節長(chang)）與母(mu)線連接，形成連續并(bing)(bing)聯電阻(zu)，母(mu)線通電后，各并(bing)(bing)聯電阻(zu)發熱(re)(re)，因(yin)而(er)形成一條(tiao)連續的加熱(re)(re)帶。

并(bing)(bing)(bing)聯耐高溫(wen)恒功(gong)率電(dian)(dian)伴熱(re)(re)帶(dai)(dai)RDP3-J4,RDP3-J4并(bing)(bing)(bing)聯式恒功(gong)率電(dian)(dian)伴熱(re)(re)帶(dai)(dai)電(dian)(dian)源母(mu)線三根平(ping)行絕(jue)緣銅導線，在主絕(jue)緣層表面上纏繞電(dian)(dian)熱(re)(re)絲，并(bing)(bing)(bing)將該電(dian)(dian)熱(re)(re)絲每隔一(yi)定距離(li)（即發熱(re)(re)節長）與母(mu)線連(lian)接(jie)，形成(cheng)連(lian)續并(bing)(bing)(bing)聯電(dian)(dian)阻，母(mu)線通電(dian)(dian)后，各并(bing)(bing)(bing)聯電(dian)(dian)阻發熱(re)(re)，因而形成(cheng)一(yi)條連(lian)續的加(jia)熱(re)(re)帶(dai)(dai)。

HWLX（RDP2-J3）并(bing)聯恒(heng)功(gong)率(lv)電(dian)伴(ban)(ban)(ban)熱(re)帶(dai), 單(dan)相(xiang)并(bing)聯式恒(heng)功(gong)率(lv)電(dian)伴(ban)(ban)(ban)熱(re)帶(dai)單(dan)位的發熱(re)量恒(heng)定，使用(yong)的電(dian)伴(ban)(ban)(ban)熱(re)帶(dai)越(yue)長，輸出(chu)的總功(gong)率(lv)越(yue)大，電(dian)伴(ban)(ban)(ban)熱(re)帶(dai)在現場可按照(zhao)實(shi)際需要的長度任意(yi)剪切，但(dan)短(duan)不得少于(yu)1個發熱(re)節(jie)點。由于(yu)電(dian)伴(ban)(ban)(ban)熱(re)帶(dai)具有(you)柔軟性，可以方便的緊(jin)貼(tie)被伴(ban)(ban)(ban)熱(re)管道(dao)表面敷設。電(dian)伴(ban)(ban)(ban)熱(re)帶(dai)外層(ceng)有(you)銅(tong)絲屏蔽(bi)編織層(ceng)，不僅具有(you)傳熱(re)和散熱(re)作用(yong)，能提高電(dian)伴(ban)(ban)(ban)熱(re)帶(dai)的整體抗拉強度，同時還能作為(wei)安全接地(di)線(xian)使用(yong)。

中溫(wen)(wen)自(zi)(zi)控溫(wen)(wen)電伴(ban)(ban)熱(re)帶ZRZWL-20-220-J,自(zi)(zi)限(xian)溫(wen)(wen)電伴(ban)(ban)熱(re)帶工(gong)作(zuo)溫(wen)(wen)度105度，高暴(bao)露溫(wen)(wen)度135度。產品適用于普通區，廣泛應用民(min)用太陽(yang)能、地熱(re)采暖、消防、石油、化(hua)工(gong)、鋼鐵、電力、環保等工(gong)業(ye)企業(ye)的(de)(de)管(guan)線、儲罐(guan)的(de)(de)伴(ban)(ban)熱(re)保溫(wen)(wen)、抗(kang)凝、防凍。
