The Implementation Plan for Large-Scale Equipment Renewal in Key Energy Sectors, jointly issued by the General Office of the National Development and Reform Commission and the Comprehensive Department of the National Energy Administration, identifies hydropower stations as one of seven key renovation areas. It advocates "prudently advancing the renewal and retrofitting of hydropower equipment." Addressing transformer upgrades for hydropower plants, HAIHONG Electric Co., Ltd. introduces the 110kV 3D Wound Core Power Transformer, providing a green, safe, and highly reliable equipment renewal solution. This technology has received national recognition and is listed in China's Catalog of Energy-Saving Technologies and Practices Proposed for International 'Top Ten' Contests under industrial energy-saving technologies.

Recently, HAIHONG Electric was invited to Hong Kong for the 22nd Anniversary Celebration of the Institute of Operating Engineers (Hong Kong Branch). As a global leader in transformers and power equipment manufacturing, HAIHONG showcased multiple innovative technologies at the event, including 3D Wound Core Technology, Open Ventilated 3D Wound Core Dry-type Transformers, Amorphous Alloy 3D Wound Core Transformers, Ultra-compact Double-layer Substations, and Ultra-compact Integrated One-stop Super-fast Charging Stations. These advancements garnered significant attention from industry experts and attendees.

Reliability and energy efficiency of electrical equipment are paramount during offshore platform operations. Recently, the life-extension retrofit project of the Panyu offshore platform in the South China Sea adopted HAIHONG Electric’s 3D Wound Core Oil-Immersed Transformers to upgrade its power distribution system. With advantages including high safety/reliability, low losses, and strong corrosion resistance, this product delivers stable power assurance for the platform.
