Datong Tianjin Nantes high voltage AC project Tianjin North Railway Station new project 1,000kV capacitor voltage transformer (horizontal acceleration 0.5g) true type seismic test successfully passed

On 30~31 October 2025, under the common witness of experts from many units such as China Academy of electric power science and State Grid Electric Power Engineering Research Institute, Guilin power capacitor Co., Ltd. (hereinafter referred to as "Guirong company") produced Datong Tianjin Nantes high voltage exchange project Tianjin North Railway Station new project 1,000kV capacitor voltage transformer (porcelain type). In Chongqing communications research and Design Institute Co., Ltd. of China Merchants Bureau, it successfully passed the real seismic test of 0.5g horizontal acceleration, becoming the first set of 1,000kV capacitor voltage transformer (porcelain type) that passed the real seismic test of 0.5g horizontal acceleration, and the equipment seismic performance reached the industry leading level. The success of this test marks a major breakthrough in the seismic technology of ultra-high voltage equipment in China, and provides a solid guarantee for the construction of ultra-high voltage power grid in high earthquake intensity areas.

The success of the test marks that Guirong company has reached the world's leading level in the technical field of high seismic ultra-high voltage capacitor voltage transformer (porcelain sleeve type), which is also a vivid embodiment of the company's adherence to the concept of technical innovation and quality oriented, and has accumulated valuable experience for the equipment development of subsequent ultra-high voltage projects. The company will continue to uphold the concept of "leading technology and quality oriented", continue to promote the research and application of high seismic and high reliable capacitor voltage transformers, and provide a solid guarantee for the construction and safe operation of China's ultra-high voltage power grid.

In the future, Guirong company will take this technological breakthrough as a new starting point, actively participate in the construction of national ultra-high voltage power grid, and contribute more to ensuring national energy security and promoting the technological progress of the power industry!
