恒溫伴熱(re)(re)電(dian)(dian)纜在主絕緣層表面(mian)上(shang)纏繞(rao)電(dian)(dian)熱(re)(re)絲(si)，并(bing)將該電(dian)(dian)熱(re)(re)絲(si)每(mei)隔一定距離（即(ji)發(fa)熱(re)(re)節長）與母線(xian)連(lian)(lian)接(jie)，形(xing)成(cheng)連(lian)(lian)續(xu)并(bing)聯電(dian)(dian)阻，母線(xian)通電(dian)(dian)后，各(ge)并(bing)聯電(dian)(dian)阻發(fa)熱(re)(re)，因而形(xing)成(cheng)一條(tiao)連(lian)(lian)續(xu)的加熱(re)(re)帶。

并聯耐高溫(wen)恒(heng)功率(lv)電(dian)伴(ban)熱帶(dai)RDP3-J4,RDP3-J4并聯式恒(heng)功率(lv)電(dian)伴(ban)熱帶(dai)電(dian)源(yuan)母線(xian)三根平行絕(jue)(jue)緣銅導線(xian)，在主絕(jue)(jue)緣層表面上(shang)纏繞電(dian)熱絲(si)(si)，并將該電(dian)熱絲(si)(si)每(mei)隔一定距(ju)離（即(ji)發熱節長）與母線(xian)連(lian)接，形成(cheng)連(lian)續并聯電(dian)阻，母線(xian)通(tong)電(dian)后(hou)，各并聯電(dian)阻發熱，因而形成(cheng)一條(tiao)連(lian)續的(de)加熱帶(dai)。

HWLX（RDP2-J3）并聯恒功(gong)率(lv)電(dian)伴(ban)(ban)(ban)熱(re)(re)帶(dai)(dai), 單相(xiang)并聯式恒功(gong)率(lv)電(dian)伴(ban)(ban)(ban)熱(re)(re)帶(dai)(dai)單位的(de)發(fa)熱(re)(re)量恒定(ding)，使用(yong)(yong)的(de)電(dian)伴(ban)(ban)(ban)熱(re)(re)帶(dai)(dai)越長，輸出的(de)總功(gong)率(lv)越大，電(dian)伴(ban)(ban)(ban)熱(re)(re)帶(dai)(dai)在現場可按照(zhao)實際需要的(de)長度任(ren)意(yi)剪切，但短不(bu)得少(shao)于1個發(fa)熱(re)(re)節點。由于電(dian)伴(ban)(ban)(ban)熱(re)(re)帶(dai)(dai)具有(you)柔軟性，可以方便的(de)緊貼被伴(ban)(ban)(ban)熱(re)(re)管道表面敷設。電(dian)伴(ban)(ban)(ban)熱(re)(re)帶(dai)(dai)外層(ceng)有(you)銅(tong)絲屏蔽(bi)編織層(ceng)，不(bu)僅(jin)具有(you)傳熱(re)(re)和(he)散熱(re)(re)作(zuo)用(yong)(yong)，能(neng)提高電(dian)伴(ban)(ban)(ban)熱(re)(re)帶(dai)(dai)的(de)整體抗(kang)拉(la)強度，同時(shi)還(huan)能(neng)作(zuo)為安全接(jie)地線使用(yong)(yong)。
