產品簡介
JPB 型并聯高溫帶分單相帶和三相帶兩類,其結構分別與JFB型并聯式單相帶和三相帶相似,所不同的是芯線采用鍍鎳鉸線,編織層采用鍍鎳銅絲,絕緣層和護套層均采用四氟乙烯-一全氟烷基乙烯醚共聚物(簡稱 PFA)擠塑而成,能在260℃溫度下使用。

JPB型并聯式高溫電熱帶 | JPB Type Paralle connection High-temperature Electric Heating Cable | | | JPB 型并聯高溫帶分單相帶和三相帶兩類,其結構分別與JFB型并聯式單相帶和三相帶相似,所不同的是芯線采用鍍鎳鉸線,編織層采用鍍鎳銅絲,絕緣層和護套層均采用四氟乙烯-一全氟烷基乙烯醚共聚物(簡稱 PFA)擠塑而成,能在260℃溫度下使用。 | | 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 layers are made of nickel plated copper threads.And moreover the insulation and jacket layers are extruded by PFA.which can be used up to 260℃. | | | Working Principle, Characteristics and Applications | | JPB型并聯高溫帶工作原理與JFB型并聯電熱帶相同,它能維持190℃以下介質管道的伴熱保溫,它特別適用于瀝青、重油、渣油和高粘油管線的伴熱保溫,也適用于需260℃以下蒸汽掃線管道路的保溫。 | | 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 bitumen,heavy oil.residual oil and high-visconsity oils pipelines.It is also applicable to thermal insulation of steam cleaning pipes under 260℃. | |
