Standard colors:
grey blue temperature range:
Maximum maintenance temperature 65℃±5℃ (continuous power supply)
Maximum exposure temperature 105℃±5℃ (intermittent power supply)
Application temperature:
Minimum -40℃;
Thermal stability:
After 1500 cycles between 10℃ and 99℃, the cable heat generation was maintained above 95% and the heat conversion rate was 95%;
Bending Radius:
18.8mm at room temperature of 20℃, 35.0mm at low temperature of -30℃;
Insulation resistance:
When the cable length is 100m and the ambient temperature is 75℃, use a 2500VDC megohmmeter to shake the cable for one minute, and the minimum insulation resistance (between the conductor and the shield) is 1200MΩ.
Starting current:
When the electric heating cable is energized, the maximum instantaneous starting current is ≤ 0.3A/m; Use length:
Single-phase power supply: 100m, bidirectional power supply: 200m (within the specified length range, it can be cut, connected, and overlapped at will); Copper core conductor:
7×0.42、7×0.5、19×0.25、19×0.28、19×0.32； Wire Material: Tinned copper wire; PTC conductive plastics: Fluorinated type, ordinary type; Inner insulation layer:
Flame retardant type, ordinary type; Metal shielding layer:
Tinned copper wire or metal alloy wire braid; Protective insulation layer: Double flame retardant type, flame retardant type; Protection level: IP65； Graph: 
► Product Benefits
1. Flame retardants are added to the heating tape materials to prevent spontaneous combustion due to sparks or exceeding the temperature resistance, which may become a fire source, making it safer and more reliable;
2. Economical and reasonable: The installation and use costs are very economical, avoiding damage and repairs caused by accidents and ensuring service life;
3. Uniform heating and high thermal efficiency;
4. Save electricity, no environmental pollution, energy saving and environmental protection;
5. During intermittent operation, the temperature rises quickly;
6. Long service life, small starting current, good memory performance and low annual attenuation rate;
7. Easy installation and maintenance, low operating cost, can be laid flat, wound, cut at will, and can be extended at will within the allowable length range;
8. Save costs, the output power is automatically adjusted as the ambient temperature changes, and there is no need to set up an additional temperature control system for easy automatic management;
