Recently, energy giants from multiple countries around the world have reached cooperation intentions, jointly investing a large amount of resources to promote the innovation of transformer technology, aiming to provide key support for the global sustainable energy development. Against the backdrop of the global accelerated transition to clean energy, the technological upgrade of transformers, as the core equipment for power transmission and distribution, is of vital importance. It is learned that this cooperation will bring together top scientific research teams from various countries, focusing on solving the problems of transformers in improving energy conversion efficiency, reducing energy consumption and adapting to the access of new energy sources. For example, develop new types of insulating materials to enhance the insulation performance of transformers and reduce power loss; Explore more efficient heat dissipation technologies to ensure the stable operation of transformers under complex working conditions. This cooperation is expected to achieve breakthrough results in the coming years and inject new impetus into the global energy structure adjustment.
