Characteristics：The HGWF/P heating cables share the same characteristics as the HGWF/P heating cables in addition 

to the following advantages:

The maximum length of allows the use of three accompany heating cable higher than that of 

single throughout heating cable, in the case of large scale with heating cable, can balance 

network load, three phase with three core,make the electric heating more hasten is flat, 

reduces the surface heat Load, increase heat transfer area to The pipeline, increase with 

heating cable heat transfer efficiency, and maintain highest temperature.

Specification

Note: The maximum maintenance temperature of the fluid refers to the maximum process temperature to be maintained for the mediuminthe pipeline. Generally, it should not exceed the fixed value specified in this table.Use length can be doubled when single point pcwer supply two-way output.

Application
Process temperature maintenance or anti-freezing

The HGWF/P heating cable is the sames the HGWF/P heating cables, which can be used for process 

temperature maintenance of pipeline system tank, valve, pump body; antifreeze or instrument pipeline

 (meet the HGWF/P heating cable product application inspecific Applications).In particular;the 

three-phase cable is more economical and reasonable than the single-phasecable when it is used for thermal

 insulation in long-distance 1 and large-diameter pipelines, and the advantages of the three-phase cable can be better demonstrated.It can be used in explosion-proof area1,and area2。
