Recently, the Chengdu Shuangli District Power Industry Supply Chain Ecological Cooperation Conference, themed “Linking Green Energy & Power, Co-Creating an Industrial Ecological Future”, grandly commenced in Chengdu, Sichuan Province. Li Jian, Member of the Standing Committee of the CPC Committee and Vice President of Chongqing University, was invited to attend and deliver a keynote speech.

During the conference, Vice President Li Jian delivered a speech titled “Green and Intelligent Power Transmission & Transformation Equipment Technology.” He emphasized that enhancing the technical parameters and independent insulation capabilities of natural ester-based insulating oil power transformers is a crucial pathway toward achieving high-end, domestically produced development of large-scale green transformers. Breaking through eco-friendly insulating medium technology and structural design technology, as well as developing a series of independent, controllable green equipment, is of vital importance.

Against this backdrop, Depurs Natural Ester Insulating Oil, produced by Shuangjiang Energy, has demonstrated superior physicochemical and dielectric properties in tests conducted by SGS (Société Générale de Surveillance). It is currently the only product in China certified by Hitachi Energy (formerly ABB).

As a pioneer in China’s natural ester insulating oil sector, Shuangjiang Energy has successfully overcome technical barriers through innovative formula design and intelligent production processes. Its natural ester insulating oil has obtained multiple international certifications, including FM and UL in the U.S., achieving industry-leading standards in technological innovation and professional performance.

Vice President Li Jian’s public endorsement not only signifies high recognition of Shuangjiang Energy’s technical expertise but also highlights the industry-leading position of Depurs Natural Ester Insulating Oil. Moving forward, Shuangjiang Energy will continue to deepen its expertise in power insulation materials, increase investment in scientific innovation and R&D, and provide higher-quality products and services to various industries, driving the sector toward low-carbon development and green transformation.
