▲ Shuangjiang Energy Deep natural ester insulating oil was successfully applied to the world's first 110kV natural ester three-dimensional coil core transformer

In the wave of global energy transformation and green and low-carbon development, Shuangjiang Energy and Shandong Electric ushered in another milestone of cooperation. Recently, the world's first 110 kV high overload class energy efficiency natural ester insulating oil three-dimensional coil core transformer developed by Shandong Denko Electric has successfully passed all type tests, and the performance indicators have exceeded expectations. The product innovatively uses the natural ester insulating oil of Shuangjiang Energy as the insulating medium, and the coil end is insulated with Nomex high temperature resistant insulation material to improve the heat resistance of the transformer.

The natural ester insulating oil is derived from plant seeds, 100% degradable, the ignition point is higher than 360 ° C, can effectively avoid explosion accidents, the carbon emissions in the whole life cycle is only 1/64 of mineral oil, with renewable, environmental protection and low carbon and other excellent performance.

At the beginning of the project, Shuangjiang Energy carried out several repeated oil compatibility tests on a number of key transformer components, breaking the conventional mineral oil research and development thinking, breaking through the technical bottleneck, and laying a good foundation for the subsequent application of the product. At the same time, the two sides actively maintained closed technical exchanges on the basic test research of lightning shock, power frequency voltage and thermal failure of natural ester oil-paper insulation system carried out by Shandong Electric, providing strong data support for the structural design and simulation analysis of the product.

Compared with the traditional laminated core transformer, the no-load loss of the natural ester insulated oil three-dimensional coil core transformer is reduced by 20%, exceeding the primary energy efficiency standard value by 5%. The product is the first in the world to put forward the natural ester insulation oil environmental protection technology and three-dimensional coil core design structure, has successfully passed the authoritative review by the Chinese Academy of Sciences Chen Weijiang led the expert group, was identified to reach the international leading level. This provides a new path for enterprises to save energy, reduce emissions, reduce costs and increase efficiency, fills the gap in international technology, and leads the green revolution in the transformer industry.

The cooperation between the two sides demonstrates China's innovation and cooperation spirit in the field of green energy technology, and contributes Chinese wisdom and solutions to the optimization of the global energy structure and sustainable development. In the future, the two sides will deepen cooperation strategies, innovate internationally leading green energy products, and promote global energy green transformation and high-quality development.
