 2、  Working Principle

Three parallel insulated copper wires are the power supply bus wires, and the electric heating wires are wrapped around the outer insulation layer of the inner sheath, and the electric heating wires are connected with the three power supply bus wires in turn at a certain distance to form a continuous parallel resistance in every two phases. When the bus goes through three-phase electricity, each parallel resistance heats up at the same time, thus forming a continuous heating strip.
