Constructed of a semi-conductive heater matrix extruded between parallel bus wires, a self-regulating cable adjusts its output to independently respond to ambient temperatures all along its length. As temperature increases, the heater's resistance increases, which lowers the output wattage.
Conversely, as the temperature decreases, the resistance decreases and the cable produces more heat. So thermostat is not necessary in some applications. It will never overheat or burnout even when overlapped. The cable can also be cut to any length. As the result, we got an energy efficient heating cable.
SSR self-regulating heating cables provide the most versatility in heat trace designs and applications.
This product has been used for over 500,000 meters in our company's key partners, PetroChina, CNOOC,Sinopec,China Aerospace,Wanhua Chemical and other global Fortune 500 companies.
The unique advantages of Huanrui self-regulating heating cable:
1. High temperature-resistant PTC matrix material: The heating temperature of the PTC semiconductor irradiation heating matrix can be stably maintained at 110°C, which has higher thermal stability.
2. Reduce the starting current: Huanrui adopts double-layer co-extrusion technology, and the starting current in the normal power range reaches 0.5-0.7A/M, far exceeding the data of domestic peers.
3. Unique materials: Insulating materials are 100% matched with PTC semiconductor radiant heating matrix. The material has excellent weather resistance, high temperature resistance, and insulation resistance of >2000MΩ, making it safer and more reliable. Longer service life.
Never overheat or burnout when overlapped. Cut to any length. Easy to install.
SSR Series
SSR-P: Tinned copper braid provides additional mechanical and ground protection.
SSR-PB: Flame retardant thermoplastic outer jacket protects against certain inorganic chemical solutions, it also protects against abrasion and impact damage.
SSR-PF: Fluoropolymer outer jacket is used for exposure to organic or corrosive working conditions or vapor may exist.
Application
SSR is ideally used for process temperature maintenance and frost protection of large diameter pipelines, tanks, valves, flanges, and other industrial applications of high heat loss issues. It is suitable for non-hazardous area, and cable with fluoropolymer outer jacket can also be used in hazardous area and corrosive area.
