Low temperature temperature controlled heat tracing cables (self limiting electric heating strips) are widely used in civil solar and geothermal heating, as well as for heat tracing insulation, anti condensation, and anti freezing of pipelines and storage tanks in industrial enterprises such as fire protection, petroleum, chemical, steel, and power. This cable is suitable for general areas, hazardous areas, and corrosive areas.
