120000kva Electric arc furnace transformer

Product Description

•Main function and features

Furnace transformers are separated with normal power transformer with its characteristic of massive secondary currents which are the main products of Shenda Electric with many advantages both on quality and price. As an example a *0MVA unit at **0V would result in a secondary current of **5 kilo ampere. For these high secondary currents special bushings are required to be connected to the bus-bars. These bushings are specified with very specific arrangements to suit the bus-bar arrangement and cooling system. Furnace bus-bar are mostly water-cooled. The cooler are either of the oil forced (OFAF) or Oil forced water OFWF).

Shenda electric is renowned and appreciated by its reliable products performance and integrated services.
