1. , a kind of positive temp coefficient high polymer semiconductor temp control heatingcable, this accompanying-heat cable is made of the outer insulating barrier (4) that coats of metallic conduction electrode (1), heater (3) and the heater (3) of two transmissions of electricity that be arranged in parallel;

  • It is characterized in that;

    the outer low resistance transition zone (2) that all wraps in advance of each metallic conduction electrode (1), two metallic conduction electrodes (1) closely contact by low resistance transition zone (2) and heater (3) and constitute the shunt circuit, heater (3) is made by semiconducting polymer'"'"'s material that two thermal spikes have resistance positive temperature coefficient, and two thermal spike systems adopt two kinds of hemihedral crystal polymer that the different melting points of certain gradient is arranged.
