The principle of three-phase constant power electric belt and single-phase constant power electric belt are basically the same. The difference is that single-phase belt adopts single-phase power supply and three-phase triangle power supply for three-phase belt. During installation, it can also be splice at will. The minimum length of use is 6 meters. It can be used in explosive gas mixture T3 group in zone 1 and Zone 2 of the factory

1. The maximum allowable length is longer than that of single-phase electric heating belt.

2. In the case of large-scale application of electric heating belt, it can balance the load of power grid.

3. It becomes flat, reduces the surface heating load, increases the heat conduction area, and improves the heat transfer efficiency and the maximum maintenance temperature of the heating belt.
