DXW/PZ/J Type Self-Regulating Electric Heating Tape
Three parallel insulated copper stranded wires serve as power busbars. An electric heating wire is wound around the inner insulation layer, and this heating wire is connected to the power busbars AB-BC-CA-AB... in sequence at regular intervals (i.e., "heating pitch"), forming continuous parallel resistors between the three phases. When three-phase power is applied to the busbars, all parallel resistors heat up simultaneously, thus forming a continuous three-phase heating tape.
