Oil Immersed Transformer (10kV-35kV)

Oil Immersed Transformer (10kV-35kV)

Oil-immersed transformers are Yawei’s latest low-loss power transformers with copper windings. New materials and processes are applied to the transformer to realize low material loss and improve the transformer performance and structure. The transformer achieves wide application in power grids for industrial and urban and rural purposes and is especially suitable to be used in compact transformers and prefabricated substations.

Features
  • Small size and light weight;
  • Low noise, excellent heat dissipation performance and low temperature rise;
  • Reliable operation and high efficiency;
  • No impact on the environment and no need of maintenance
