JGB型并聯式高溫電熱帶

JGB Type Parallel Connection High-temperature Electric Heating Cable

（1）產品結構：Product Structure

JGB型并聯高溫帶分單相帶和三相帶兩類，其結構：編織層采用金屬絲編織，絕緣層和護套層均采用云母與無機含氟塑料擠塑而成，通過熱隔處理能在400℃介質溫度下使用。

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）產品工作原理、特點和適用場所：Working Principle, characteristics and Applications

JGB型并聯高溫帶工作原理，它能維持400℃以下介質管道的伴熱保溫，它特別適用于蒸汽吹掃管道的保溫。

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：額定電壓為380V的非標單相高溫帶，型號表示為：“JGB-□/2（380V）”，其主要技術參數除“單電源zui大使用長度”為同規格單相帶的zui大使用長度”為同規格單相帶的

倍外，其余均與同規格的單相帶相同。

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.
