Types:

High impedance furnace transformer, DC arc furnace transformer, ladle refining furnace transformer, submerged arc furnace transformer (including ferroalloy furnace tran- sformer, calcium carbide furnace transformer, yellow pho- sphorus furnace transformer,single phase titanim slag furnace transformer etc.), electro slag furnace transformer, frequency induction furnace transformer, single-phase graphite furnace transformer, et

Features:

Take on-load tap furnace transformer with “8”-shaped winding which is developed independently for example.

1.Wide range of voltage-regulate. Secondary voltage of differential voltage levels meets the arc furnace steel-making process requirements.

2.High-voltage has no restriction of switching insulation level, and it (e.g. 110kV) can be reduced to low-voltage directly, eliminating the intermediate substation and saving more than 30% invested.

3.Choose suitable voltage-level load tap changer and be accessed compensation capacitor.

4.The main transformer works in constant flux density.

5.Using the same reverse-phase parallel, electric (or magnetic) shielding, transposed conductors

6.A separate voltage coil is used so that ampere-turn balance is good, coupled with cylinder pressure nail structure

7.Using third breaking off instead of primary breaking off.

8.real energy-saving emission reduction innovative product.Take 31500/110 arc furnace transformer for example, the load loss, no-load loss, no-load current is dropped 13%, 17%, 26% compared with the original product respectively.
