WanLian Group introduces foreign technology to produce self-regulating heating cables (also known as self-limiting temperature heating cables overseas) that are widely used in the pipeline and tank insulation, anti-icing, frost prevention, floor heating, and snow melting in gutters of industrial enterprises in the oil, construction, food, chemical, steel, and power sectors. This heating cable is suitable for ordinary areas, hazardous areas, and corrosive areas.

Section 3: Application Scope
(ZR) GWK Flame Retardant and Explosion Proof (High Temperature) Self-Limiting Temperature Electric Trace Heating (also including models such as GBR, KTV, GXW, GKW, GWK, GBW, DZL, etc. of self-limiting temperature electric trace heating) is widely used in process pipelines, tank heating insulation, and frost prevention insulation in the petrochemical, steel, electric power, and other industries. The medium temperature maintenance range is 0～135℃.
1. Basic electric heating tapes are generally used in places without explosion-proof or anti-corrosion requirements, and with low environmental humidity.
2. Protective electric heat tapes are generally used in places without explosion-proof or anti-corrosion requirements, but with high environmental humidity.
3. Explosion-proof electric heaters are generally used in environments that require explosion prevention but not corrosion prevention, with moderate humidity levels.
4. Explosion-proof heating cables are generally used in environments with explosion-proof requirements but no corrosion resistance, and high humidity.
5. Explosion-proof and corrosion-resistant electric heating tapes are generally used in environments that require explosion-proof and corrosion-resistant protection, with high humidity levels.
6. If flame retardancy is required, select the corresponding flame retardant series.
