Constant Wattage Series Heat Trace Cable (CWSHT)

Series resistance-type heater cables use single or multiple resistive conductors to create a heating circuit. Power output of thesecables is relatively constant and as voltage is applied, the power output is determined by a combination of the length of the cableand the overall resistance of the conductor. heating cable's current and resistance is equal to all length heating cable, so theheating value of each unit is equally, not result in the power of terminal end is lower than beginning end with the increasinglength of heating cable, so it is suit for long line pipes and large diameter pipe's heat tracing or temp. maintenance, the cable can NOT cut to be length.
