Product Introduction: Hengxin Cable's high-temperature self limiting temperature electric heating belt (also known as self controlled temperature electric heating belt, self regulating heating cable) is widely used for heat insulation, anticoagulation, and antifreeze of pipelines and storage tanks in industrial enterprises such as petroleum, chemical, steel, and power. This cable is suitable for ordinary areas, hazardous areas, and corrosive areas.

Recommended occasions: Suitable forPipeline antifreezeTemperature control of equipment and containersPipeline heat tracingInsulation and heating, especially when the materials are prone to decomposition, deterioration, crystallization, condensation, and freezing. It has a wide range of applications in the production, processing, and other sectors of petroleum, chemical, power, metallurgy, light industry, food, refrigeration, construction, gas, agricultural and sideline products.

High temperature series self limiting electric heating belt: GWL (GWK, GXW, GKW, ZKWG, GBW) corresponds to foreign models XTV series

Cable structure:

1. Copper core wire: 7 × 0.50, 19 × 0.32, 19 × 0.41

2. Conductive plastic layer: ordinary PTC, flame-retardant PTC, fluorine-containing PTC

3. Insulation layer: modified polyolefin, flame-retardant polyolefin, fluorinated polyolefin, perfluorinated material

4. Shielding layer: Tin plated soft round copper wire, covering a density of 80%

5. Sheath layer: modified polyolefin, flame-retardant polyolefin, fluorinated polyolefin, perfluorinated material

Technical indicators:

1. Standard color: Red

2. Temperature range: maximum working temperature of 130 ± 5 ℃; The maximum exposure temperature is 150 ℃; Maximum temperature tolerance: Modified polyolefin 105 ℃, flame retardant polyolefin 105 ℃, fluorinated polyolefin 180 ℃, perfluorinated material 205 ℃

3. Construction temperature: minimum -40 ℃

4. Thermal stability: After cycling back and forth 300 times between 10 ℃ and 149 ℃, the cable's heat generation remains above 90%.

5. Bending radius: 38.5mm at -20 ℃- 49.0mm at 30 ℃

6. Insulation resistance: When the cable length is 100m and the constant temperature water is 75 ℃; The minimum insulation resistance for testing is 20M Ω, with shielding or explosion-proof protection type. At room temperature of 20 ℃, shake test with 2500VDC between the shielding layer and the conductive wire core for 1 minute, and the minimum insulation resistance is 1200M Ω.
