How to determine the working voltage of resistance furnace

      The power supply voltage of the resistance furnace is mainly determined according to the power supply and the requirements of the furnace. Generally, 380V or 220V power supply is directly used for resistance furnaces. Some electric furnaces must use very low voltage because of special requirements and need to install transformers to achieve the purpose.

    In general, 220V series or parallel series power supply is adopted for resistance heating elements with power below 25kW, and 380V star or triangle line power supply is generally adopted for electric heating elements of resistance furnaces with power between 25kW and 75kW. For resistance furnaces with a power of more than 75kW, the power supply modes of electric heating elements are relatively diversified. The purpose is to ensure that the power of each heating element is appropriate, which is convenient for element manufacturing and control of furnace power and temperature.
