Three Phase Oil-Immersed Transformer Product features
1. The transformer core is made of high-quality cold-rolled silicon steel sheets,which is tensioned by steel tension belt, forms a
solid frame structure with the clamp. The layers gap is small, and the joints of each layer are staggered, which greatly reduces
the no-load loss and current and noise.
2.The transformer coil adopts high-purity oxygen free copper, which effectively reduces the copper loss; The cushion block and
brace are rounded, the electric field is uniform, and the reliability is enhanced. The inner winding support is strengthened to improve
its stability and prevent instability and deformation, and improve the short-circuit resistance of the transformer.
3.The transformer is fully sealed and free for maintenance to prolong usage life to more than 30 years.
