Three-phase Oil-filled Transformer
Oil-immersed transformer is a new high-performance transformer with a more reasonable structure and better performance. Stable performance, low loss and low noise. Oil-immersed transformers are mostly suitable for power grid transformation of urban and rural, industrial and mining enterprises. Suitable for combined transformers and pre-installed substations.
Description
The three-phase oil-filled transformer adopts a new type of insulation structure with strong short-circuit resistance. The iron core is made of high-quality cold-rolled silicon steel plate. The high-voltage winding group is composed of high-quality oxygen-free copper wire and adopts a multi-layer drum structure. All fasteners are specially treated to prevent loosening.
