35kV Oil-immersed Power Transformer

35kV class & 10,000kVA max oil-immersed power transformer for efficient voltage transformation and power distribution.

All windings adopt semi-rigid self-adhesive transposed conductor design, which significantly improves the short-circuit withstand capability of the transformer and reduces hot spot temperature rise.
Multiple noise reduction measures are adopted to effectively lower the noise level (5 dB lower than the national standard).
The transformer tank can withstand full vacuum and realize full-vacuum oil filling, laying a solid foundation for reliable and long-service-life operation.
The self-developed on-line monitoring system enables all operating parameters of the transformer to be connected to the Internet of Things (IoT).
