1000MVA/1000kV UHV transformer has the highest voltage level and the largest capacity, representing the most advanced design and manufacturing ability.

In March 2017, the 1000MVA/1000kV UHV transformer independently developed by Taikai Transformer passed all the factory tests and type tests at one time. In July, it successfully passed the national-level technical appraisal.

Taikai's 1000kV transformers are characterized by high insulation reliability, low local discharge, low loss, and low noise, leading globally.
