Low temperature/medium temperature/high temperature/self-limiting temperature explosion-proof electric heating cable are widely used in oil, natural gas, construction, medicine, food, chemical, steel, power and other industrial enterprises in the pipelines and storage tanks for heat insulation, anti-coagulation, anti-freezing, gutter snow melting and other fields. The heating cable is suitable for general areas, hazardous areas and corrosive areas.
