Self regulating Heating cable


Self regulating heating cable provide the most versatility in heat trace design and applications. Constructed of a Semiconductive heater matrix extruded between parallet buswires, a self regulating cable adjusts its output to independently respond to ambient temperatures all along its length. As temperatures increase,the heater's resisteance increase which lower the output wattage. Conversely, as the temperature decrease, the resistance decreases and the cable produces more heat. So it is no need thermostat in some applications. It will never overheat or burnout even when wrapped by itself(overlapped). Also can be cut to any length. It is an convenient maintenance,easy use and energy efficient heating cable.
Self regulating electric heating cables are uesd 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.

Features

•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 down time.
•Can be single overlapped without burn- out, which simplifies heat tracing of in-line process equipment such as valves, elbows and pumps.
•Because of self-regulating, overtem- perature conditions are minimized.
•Connection Kits reduce installation time.

Structure and Index
Structure

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 buss wires and provides corrosion resistance.

D. Tinned Copper Braid 

 Provides additional mechanical protection in any environ- ment and a positive ground path.

E. Modified polyolefin outer jacket or Fluoropolymer Overjacket 

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