Product Structure

JPB 型并联高温带分单相带和三相带两类，其结构分别与JFB型并联式单相带和三相带相似，所不同的是芯线采用镀镍铰线，编织层采用镀镍铜丝，绝缘层和护套层均采用四氟乙烯-一全氟烷基乙烯醚共聚物（简称 PFA）挤塑而成，能在:namespace prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" />260℃温度下长期使用。

JPB type parallel connection high-temperature electric heating cable has two types:single phase and three phase.Theirs are made of nickel-plated stranded copper wires and the braided s are made of nickel plated copper threads.And moreover the insulation and jacket s are extruded by PFA.which can be used up to 260℃.

Working Principle Characteristics and Applications

JPB型并联高温带工作原理与JFB型并联电热带相同，它能维持190℃以下介质管道的伴热保温，它特别适用于沥青、重油、渣油和高粘油管线的伴热保温，也适用于需260℃以下蒸汽扫线管道路的保温。

The working principle of JPB parallel connection high temperature cable is the same as JFB parallel connection electric heating cable. It can maintenance media temperature in pipes below 190℃.It is especially suitable to the thermal insulation of bitumenheavy oil.residual oil and high-visconsity oils pipelines.It is also applicable to thermal insulation of steam cleaning pipes under 260℃.
