The three-phase constant power heating belt and the single-phase constant power heating belt are basically the same, the difference is that the single-phase power supply is used for the single-phase belt, and the three-phase triangle power supply is used for the three-phase belt. It can also be spliced at will during installation. The shortest length is 6m. It can be used in T3 group of explosive gas mixture in zone 1 and zone 2 of the factory.
Product specifications and main technical parameters

Product features
In addition to the same characteristics as the single-phase heater, the three-phase heater also has the following advantages:
1. The maximum allowable length is longer than that of single-phase heater.
2. In the large-scale application of electric heating belt, it can balance the load of power grid.
3. More flat, reduce the surface heating load, increase the heat conduction area, improve the heat transfer efficiency and the maximum maintenance temperature of the heating belt.
