Self Regulating Heating Cable

12~380V Electric Heat Tracing Self Regulating Heating Cable

Link solar self-regulating heating cables provide the most versatility in heat trace designs and applications. Constructed of a semi-conductive heater matrix extruded between parallel bus wires, self regulating heat trace 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 for some applications. It will never overheat or burnout even when overlapped. The cable can also be cut to any length. As a result, we got an energy-efficient heating cable.

Link solar self-regulating heating cable is resistant to watery and inorganic chemicals and protected against abrasion and impact damage.

Easy heat Self regulating electric heating cables are used for pipes, equipment and containers temperature control, heating, insulation, heating, in particular, where the material is easy to break down, deterioration, crystallization, condensation freezing. In the petroleum, chemical, power, metallurgy, light industry, food, frozen, construction, gas, agricultural and sideline products production, processing and other departments have a wide range. We have self regulating gutter heat cable and self regulating roof heating cables and so on. you can choose where you want to use it.

•Energy-efficient, self-regulating cable uses less energy when less heat is required.
•Easy to install, can be cut to any length (up to max circuit length) in the field.
•lower installed cost than steam tracing, less maintenance expense, and less downtime.
•It can be single overlapped without the burn- out, which simplifies heat tracing of in-line process equipment such as valves, elbows, and pumps.
•Because of self-regulating, overtemperature conditions are minimized.
•Connection Kits reduce installation time.

Self Regulating Heating Cable

A. Twin Copper Buss Wires 

Pro- vide reliable electric current capability.

7*0.32mm, 7*0.42mm, 7*0.5mm, 19*0.32mm, 19*0.41mm and etc.

B. Self-regulating conductive core         

“Self-Regulating” component of the cable its electrical resistance varies with temperature. As process temperature drops, the core’s heat output increases; as process temperature rises, the heat output decreases.

C. Modified polyolefin jacket 

 Flame retardant electrically insulates the matrix and bus wires and provides corrosion resistance.

D. Tinned Copper Braid 

 It provides additional mechanical protection in any environment and a positive ground path.

E. Modified polyolefin outer jacket or Fluoropolymer Overjacket 

Corrosion-resistant, flame retardant over jacket is highly effective in many environments. Protects against exposure to organic or corrosive solutions. The jacket also protects against abrasion and impact damage.
