Quick Detail:

1.Low loss, low noise

2.Low partial discharge

3.High quality,efficiency

4.Safe use

5.Electric arc furnace transformer

Description:

Furnace transformer is power transformer which is used on industry furnace smelting, it’s a special transformer which is designed according to work principle, lead character and operation characteristic. It contains steel-making arc furnace transformer ladle refining furnace transformer, electro slag furnace transformer, submerged arc furnace transformer(ferroalloy furnace, calcium carbide furnace, phosphorus furnace and so on).all kinds of transformers which are use on alternative current furnace such as power frequency induction furnace transformer.

It has more stringent requirements in electric, magnetic, thermal, mechanical and other aspects compared with other transformers, and has to comply with the operation process of various furnace transformers and load characteristics, so that it can meet users, and facilitate energy-saving emission reduction and other conditions.

There are many kinds of furnace transformers. The company mainly produce the following products:

High impedance furnace transformer, DC arc furnace transformer, ladle refining furnace transformer, submerged arc furnace transformer (including ferroalloy furnace transformer, calcium carbide furnace transformer, yellow phosphorus furnace transformer, single phase titanium slag furnace transformer etc.), electro slag furnace transformer, frequency induction furnace transformer, single-phase graphite furnace transformer, etc.

Take on-load tap furnace transformer with “8”-shaped winding which is developed independently for example, the features as fellows:

The transformer is a arc furnace power transformer which is used to make a high-quality steel and alloy smelting arc furnace. It consists of series voltage regulator transformer and main transformer which are mounted on the same tank. The two low-voltage winding are made of the “8”, replacing the cumbersome welding process between two low-voltage windings.
