Applying the rated voltage to the core wire, the current passing through the heating core generates joule heat (Q=0.24I²RT). A constant-power series electric heating tape utilizes this heat to insulate and preserve the temperature of the object requiring heat retention. Due to consistent current throughout, the constant-power series electric heating tape maintains uniform power and temperature. The structure of the constant-power series electric heating tape is simple and easy to maintain, with a supply length of up to 3KM from a single power source. This product requires custom design and production based on the pipe length and required power, and cannot be arbitrarily cut on-site.
