DWL low temperature series self-limiting temperature electric heating cable series: DWL (DWK, DXW, DKW, ZKWD, DBW) corresponding to foreign models BTV series
The low-temperature series self-limiting electric heating cables developed by the company are widely used in civil solar energy, geothermal heating, fire protection, petroleum, chemical, steel, electric power and other industrial enterprises for pipelines, storage, heat tracing, anti-condensation, and antifreeze. The heating cable is suitable for ordinary areas, Silicone rubber electric Cable dangerous areas and corrosive areas.

Low temperature series self-limiting temperature electric heating cable product model:

Low temperature self-limiting electric heating cable structure:

①Silicone rubber flat cable Copper conductor: 7 × 0.32; 7 × 0.42; 7 × 0.50; 19 × 0.32;
② Conductive plastic layer: ordinary PTC; flame retardant PTC;
③ Insulation layer: modified polyolefin; flame retardant polyolefin;
④ Shielding layer: aluminum-magnesium alloy wire (covering density 70%);
⑤ Sheathing layer: modified polyolefin; flame retardant polyolefin; perfluoro material

silicone control cable manufacturers  Technical indicators:
1. Standard color: black;
2. Temperature range:

——The highest working temperature is 65 ± 5 ℃;
——The maximum exposure temperature is 85 ℃;
3. Construction temperature: minimum -40 ℃;
4. Thermal stability: After cycling back and forth from 10 ℃ to 99 ℃ for 300 times, the heating value of the heating cable is maintained above 90%.
5. Bending radius: 25.4mm at -20 ℃; 35.0mm at -30 ℃;
6. Insulation resistance: When the length of the heating cable is 100m and the temperature is 75 ° C, the minimum value of the insulation resistance is 20MΩ, which is shielded or explosion-proof. At room temperature, use 2500VDC to shake between the shield and the conductive core for 1 minute The minimum insulation resistance is 20MΩ.

product advantages:
1. The temperature of the heat tracing pipeline is uniform, will not overheat, and is safe and reliable;
2. Save electricity;
3. During intermittent operation, the heating starts quickly;
4. Low installation and operation costs;
5. Easy installation and maintenance;
6. Facilitate automated management;
7. Silicone rubber variable frequency cable No environmental pollution.
