Low-Temperature Self-Regulating Heat Tracing Cable

The low-temperature self-regulating heat tracing cable uses two parallel bus wires and a PTC semiconductor polymer heating core tape. The core tape automatically adjusts output according to local pipe temperature changes: power increases when the temperature drops and decreases when the temperature rises. It is suitable for freeze protection, anti-freezing, and maintaining process temperatures up to 65°C for pipelines, valves, tanks, and equipment in water supply and drainage, fire protection, petrochemical, and other industries.
