The 345KV fully insulated power transformer project, including design, engineering, manufacturing, testing, delivery, installation and trial operation

【Project Overview 】
This project represents our pinnacle achievement in the field of ultra-high voltage and large capacity transformers. This 345KV/250MVA fully insulated autotransformer is extremely complex in terms of design, manufacturing, and testing. We utilized the most advanced electric field simulation technology to optimize the insulation structure; adopted low-loss core materials and staggered conductors to keep the no-load loss at an extremely low level; and completed all demanding tests including long-term induced voltage with local discharge measurement in the factory.
The equipment was safely transported to the site via international logistics and installed and oil treatment were guided by our senior engineers. Finally, it passed the on-site withstand voltage test and successfully connected to the grid in one go. This project demonstrates our comprehensive capabilities in design, manufacturing, and project management in the world's top power transmission and transformation equipment market.
