High temperature self-control series

A series of red high temperature self-regulating electric heating cables (self-regulating electric heating cables) developed by Shandong Huaning are widely used for heating, heat preservation, preventing coagulation and freezing of pipelines and storage tanks.

Product Details

Application area

Self-regulating high-temperature series heating cables are widely used in fire, oil, chemical, metallurgical, electric power, environmental and other industrial plants for heating, heat preservation, preventing coagulation and freezing of pipelines and storage facilities. Tanks. The electric heating tape is suitable for common areas, hazardous areas and corrosive zones, after use together with a power explosion-proof distribution box, it is suitable for use in the explosive gas mixture "T4-T6" of the first and second groups. Areas of the plant, which are not directly affected by external forces.






Product Number Rated power at 10 °C: 10 W/m, 15 W/m, 20 W/m, 25 W/m, 30 W/m, 35 W/m, 40 W/m, 45 W/m, 50 W/m, 55 W/m, 60 W/m, 65 W/m


Temperature Class: High Temperature Series (G)

Design Type: Explosion Proof Type (PF)

Voltage Level: 220 V, 380 V





Structural Principle (5) Shell Layer: Perfluorinated Material GWK GWK (^)


(1) Copper core tire: 7 × 0.5

(2) Heating core belt: Fluorine PTC (polymer composite conductive material)

(3) Insulation layer: Perfluorinated material

(4) Shielding layer: a sheath of tinned copper wire or a braid of another metal wire with a coating density of ≥ 80%.






Product Parameters



(1) Standard Color: Yellow/Red

(2) Temperature Characteristics: The maximum operating temperature of GWK is 120 °C, the maximum sustained temperature is 200 °C (the temperature of the sustained tape core).

GWK (^) The maximum operating temperature is 150 °C and the maximum sustained temperature is 250 °C (sustained tape core temperature).

(3) Design temperature: minimum-60 °C for fluoride materials.

(4) Start current: ≤ 0.9 A/m/≤ 1.1 A/m

(5) Thermal stability: After the electric heating belt has passed the thermal performance test, its power should be maintained at 90% of the original value.

(6) Bending radius: 30mm at-20 °C, 50mm at-30 °C

(7) Insulation resistance: The insulation resistance between the electric heating conductor and the metal shielding layer shall not be less than 50 MOM.








(1) Automatic power output adjustment and compensation according to the actual heat quantity, the required electric heating system. It is a new generation of constant temperature energy-saving heaters.

(2) It can be arbitrarily shortened or lengthened within a certain range, and it allows multiple overlapping without fear of overheating and igniting.

(3) Low temperature, fast start and uniform temperature, as each part can be automatically adjusted due to the temperature change of the heater part.
