Self-regulating heating cable is made of nano conductive carbon grains,two paralleled busbars and insulation layers,because of the parallel structure,all heating cables can be cut to any length on the scene,connect with two-way or three-way connection.
Nano conductive carbon grains In the heating cable,the circuit number of busbar changes depends on the ambient temperature influence.When the ambient temperature gets cold,electric conductive plastic make the scintilla shrink and then connect a circuit,current flows through these circuits,and then cable heats.
When temperature rises ,metallised plastic leads to expansion of scintilla,carbon granules separate slowly,lead the circuit dropout,resistance rises,cables will reduce the power output.
When ambient temperature gets cold,plastic will recover the state of scintilla shrink,carbon granules connects with each other and form a circuit,cables heating power will rise.
Self-regulating heating cable have much more advantages than normal heating cable ,the temperature he controls not too high or too low,because the temperature is Self-regulated.
Self-regulating heating cable(For short:Self-regulate heat tracing cable,Self - limiting temperature cable)is the only generation of single-band constant temperature electric heater.The resistivity of the heat element has a high positive temperature coefficient(PTC) and parallel to each other.Its characteristic:Can limit the temperature when heated automatically and and adjusts the output power with the temperature of the heated system automatically without any additional equipment.Can be arbitrarily cut off or use in a certain length.
Electric heating cable has the function that adjust the output power automaticlly,so it would not burn becuase of the heat of itslef, but because of the actual need for heat and compensate, so become a new generation of energy saving and thermostat heater.
It starts quickly when in low temperature condition with temperature uniformity,so very part of the heated object can be adjusted by the self-regulated heating
It can be installed and maintain easily,also used in all day with high automation level and low maintenance fee.
It has the advantage of safty,reliability,wide usage, environmental protection and long life.
