              三(san)根平(ping)行(xing)的(de)絕緣(yuan)銅(tong)線為電源母線,在內護(hu)套(tao)絕緣(yuan)層外(wai)纏繞(rao)電熱(re)絲(si),並(bing)將該(gai)電熱(re)絲(si)每(mei)隔壹定距(ju)離分(fen)別依次與三(san)根電源母線循環連(lian)接,在每(mei)二相間(jian)形(xing)成(cheng)連(lian)續並聯(lian)電阻(zu)。當(dang)母線通以(yi)三(san)相電後(hou),各(ge)並聯(lian)電阻(zu)同(tong)時發(fa)熱(re),因(yin)而形成(cheng)壹條連續的(de)加(jia)熱(re)帶
          Three parallel insulation copper wires form power generatrix. Electric heating threads are wound around the inner jacket insulation layer ln every certain distance, the heating thread is welded in turn to the three power generatrix circularly. This makes every 2 phases into acontinuous parallel connection resistance. When the generatrix is connected to 3 -phase power supply, the every parallel resistance heats at the same time This makes a continuous heating belt.

          Product Characteristics and Applications

          三(san)相電熱(re)帶除(chu)有單(dan)相電熱(re)帶相同(tong)特(te)點(dian)外(wai),還(hai)有(you)以(yi)下(xia)優(you)點:
          Besides the above characteristics the three phase heating cables have following advantages:
          率的(de)三(san)相電熱(re)帶的(de)zui大(da)允許使(shi)用長度是(shi)單(dan)相電熱(re)帶的(de)三(san)倍。
          The most tolerable length of the three-phase heat cable is three times longer than the length of the single-phase heating cable of the same wattage.
          三(san)相帶截面大(da),傳熱(re)導面積(ji)大,能提(ti)高(gao)傳輸效率。

          Bigger section area of three phase heating cable can broaden heat transmitting area and thisincreases the transmitting efficiency.

          三(san)相並(bing)聯(lian)帶壹般適用(yong)於(yu)大管徑,管網系統(tong)管線和罐(guan)體(ti)的(de)伴(ban)熱(re)保(bao)溫(wen)。

          Three phase parallel connection heating cables are suitable forthethermal insulation of pipes with big diameters, pipe lines in nets and tanks.
