JGB型并联式高温电热带

JGB Type Parallel Connection High-temperature Electric Heating Cable

（1）产品结构：Product Structure

JGB型并联高温带分单相带和三相带两类，其结构：编织层采用金属丝编织，绝缘层和护套层均采用云母与无机含氟塑料挤塑而成，通过热隔处理能在400℃介质温度下使用。

JGB type parallel connection high-temperature electric heating cable has two types: single phase and three phases. Their structures are similar to the single phase and three phases respectively of JPB type. The braided layers are made of metal threads, and the insulation and jacket layers are mica tape and excruded by inorganic polyfluoric plastic material, which can be used up to 400℃ media temperature via thermal enclosure measure.

（2）产品工作原理、特点和适用场所：Working Principle, characteristics and Applications

JGB型并联高温带工作原理，它能维持400℃以下介质管道的伴热保温，它特别适用于蒸汽吹扫管道的保温。

The working principle of JGB type parallel connection high temperature cable is the same as JPB type parallel connection heating cable. It can maintain media temperature in pipes below 400℃. It is especially suitable to the thermal insulation of steam cleaning pipes.

注：额定电压为380V的非标单相高温带，型号表示为：“JGB-□/2（380V）”，其主要技术参数除“单电源zui大使用长度”为同规格单相带的zui大使用长度”为同规格单相带的

倍外，其余均与同规格的单相带相同。

Note: The non-standard single phase type high temperature cable of rated voltage 380V is marked by “JGB-□/2（380V）”. The main technical parameters are the same as those of single phase cable in same wattage, except that the maximal use length is

times longer than single phase cable.
