工艺：恒功率加热带、电热带它是由母线、母线绝缘层、主绝缘层发热丝外护套、屏蔽层和最外加强保护套组成。

   用途：适用于管道、容器表面敷设

   特点：当温度上升时，发热功率减小，当温度下降时，发热功率增大。起动冲击小耐蚀性能好，使用寿命长，能剪切使用等优点。

Technology: constant power and the tropics, Dianredai it from the bus, bus insulation layer, the heat insulating layer of silk jacket, shield, and strengthen the protection of the kit components.
Use: apply to pipeline laying vessel surface
Features: When the temperature rises, fever power decreases when the temperature is decreased, increasing heating power. Starting impact on the corrosion resistance of a good, long life, to the advantages of the use of shear.
