HGWF/P-□-3/J□Three-phase Parallel Constant Power Heating Cable
Structure
1/ Tin plated copper busbar
2/ Power insulation Layer
3/ Inner sheath insulation Layer
4/ Ni-Cr heating element
5/ Outer sheath insulation Layer
6/ Woven sheath
Optional parts
7/ Fluorinated plastic sheeting outside the braided layer provides additional protection against exposure tochemicals or corrosionand braided layers in pipes Laid underground.
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。
