Power Transformer
Power Transformer as Step-down transformer in substations and step-up transformers in power station are essential components in those facilities. These transformers cover the electric power for many of electricity consumers, so highly reliable transformer are required.
Fuji Tusco provide the highest efficiency transformer within the limits where economy is not lost. Because of well arranged core construction, no-load loss is reduced.
In relation, to the load loss occupying the majority of total loss, as a result of employing a transposed conductor, achieving non-magnetization of metal adjacent to the winding, and providing a magnetic shielding of tank inner wall, stray-load loss has been reduced significantly whereby transformer with high efficiency and little loss have been created.
