High-Temperature Self-Regulating Heat Tracing Cable

The high-temperature self-regulating heat tracing tape uses a semiconductor self-regulating heating core tape and parallel circuits that can be cut on-site. It automatically adjusts output along the heating loop according to ambient temperature and thermal loss of the insulation layer. It is suitable for frost protection and maintaining a process temperature up to 150°C for high-temperature process pipelines, valves, instrument lines, storage tanks, and equipment, and can withstand intermittent high temperatures caused by steam purging.

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.

  • PTC core tape adjusts heating output segment by segment, adapting to different heat dissipation at various pipe positions
  • Parallel busbar structure, can be cut to installation size within the specified maximum loop length
  • self-regulating feature reduces the risk of continuous overheating at overlapping installation positions
