The world's first domestically produced 500 kV vegetable oil transformer was successfully developed. Each piece of equipment can reduce carbon emissions by approximately 70 tons during its entire life cycle.

This transformer has the characteristics of extremely low fire risk, low life cycle cost, and strong overload capacity. Compared with traditional

500 kV mineral oil transformers, this transformer is safer and more environmentally friendly. Each piece of equipment can reduce carbon emissions by approximately 70 tons (equivalent to (compared to the carbon emissions of 270,000 cars driving one kilometer or the carbon absorption of 14,000 trees in one day), it has good social and economic benefits and promotion value.

The breakthrough in key technologies for the development of large-scale vegetable oil transformers marks a milestone breakthrough in the localization of my country's green large-scale power equipment. It will effectively promote the construction of new energy systems and new power systems, serve the country's "double carbon" goal, and boost the industry's sustainability Sustained and healthy development.
