| Single-phase constant power electric heating cable |
I. Product structure and working principle The power bus is two parallel insulated copper wires. The heating wire is wound on the inner insulation layer, and the heating wire is connected to the bus at a certain distance (ie, "heating section length") to form a continuous parallel resistance . After the bus is energized, each parallel resistor heats up, thus forming a continuous heating cable.
The single-phase constant power heating cable is mainly used for antifreeze and heat preservation of pipes and meters everywhere, with a maximum maintenance temperature of 150 ° C. It can be used in explosive gas applications in the first and second zones of the factory.
