What is an electric furnace transformer？

Furnace transformers are special - purpose transformers specifically used for electric arc furnaces, resistance furnaces, and other industrial electric furnaces. Its main function is to convert the high - voltage electrical energy provided by the power grid into low - voltage, high - current electrical energy suitable for the operation of electric furnaces. Furnace transformers are widely used in industries such as metallurgy, chemical engineering, and ceramics. The following are some key knowledge points of furnace transformers:

Definition and Characteristics：

• Definition: A furnace transformer is a transformer specifically designed for electric furnaces, used to convert the high - voltage electrical energy of the power grid into low - voltage, high - current electrical energy suitable for the operation of electric furnaces.
  Characteristics:

• High Current: Furnace transformers can provide high current to meet the high - power requirements of electric furnace heating.

• Low Voltage: The output voltage is usually low to meet the working requirements of electric furnaces.

• High Heat Resistance: Furnace transformers need to work in high - temperature environments, so they have good heat - resistant properties.

• High Reliability: Furnace transformers need to operate continuously for a long time, so they have high reliability and a long service life.

• High Efficiency: Furnace transformers usually have high efficiency to reduce energy loss and improve energy efficiency.
