Product Features

The medium temperature series self-regulating electric heating belt is widely used in the heating, anti-coagulation and anti-freezing of pipelines and storage tanks of industrial enterprises such as civil solar energy, geothermal heating, fire protection, petroleum, chemical, steel, electric power and environmental protection. The electric heating belt is suitable for general, hazardous and corrosive areas. After being used with the explosion-proof power supply junction box, it is suitable for the “T4—T6” group of explosive gas mixture in the first and second zones of the factory which is not directly impacted by external force.

Temperature class: medium temperature (Z) series
Structure type: basic type (J), shielded explosion-proof type (P), protective type (F), explosion-proof protection type (PF), explosion-proof and anti-corrosion type (PF2, PF46)
Voltage level: 36V, 110V, 220V, 380V
10°C nominal power: 35W/m, 40W/m, 45W/m, 50W/m, 60W/m
Explosion-proof mark: ExeIICT4 Gb
(1) Copper core busbar: 7 × 0.50, 19 × 0.32, 19 × 0.41
(2) Heated core tape: ordinary PTC, flame retardant PTC, fluorine-containing PTC
(3) Insulation layer: modified polyolefin, flame retardant polyolefin, fluorine-containing polyolefin, perfluorinated material.
(4) Shielding layer: tinned copper wire braid or other wire weave, covering density ≥75%.
(5) Sheath layer: modified polyolefin, flame retardant polyolefin, fluorine-containing polyolefin, perfluorinated material

(1) Standard color: brown

(2) Temperature range: the maximum maintenance temperature is 90±5°C, and the maximum temperature is 125°C (the core belt withstands the temperature)

(3) Construction temperature: polyolefin minimum -40 °C, fluorine material minimum -30 °C

(4) Starting current: ≤0.6A/m

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

(6) Bending radius: 30.4mm at -20°C and 40.6mm at -30°C

(7) Insulation resistance: The insulation resistance between the electric heating conductor and the metal shield should not be less than 500 MΩ


(1) Automatically adjust the output power and compensate according to the actual heat demand of the heat tracing system. It is a new generation energy-saving constant temperature heater.
(2) It can be arbitrarily truncated or used within a certain range, and allows multiple overlaps without high temperature hot spots and burnout.
(3) Low temperature state, quick start, uniform temperature, because each part can be automatically adjusted due to temperature changes in the heat tracing.
(4) Easy installation, simple maintenance, all-day service, high level of automation, low operating and maintenance costs.
(5) Safe and reliable, wide use, no pollution to the environment, long life.
