As the world’s largest provider of smart device exterior structures and module solutions, Biel Crystal has established a large-scale new factory in Hai Duong Province, Vietnam (hereinafter referred to as Biel Crystal Hai Duong Plant), marking a significant step in its global strategy. HAIHONG Electric as Biel Crystal’s partner for factory power distribution systems, has consistently supplied highly reliable 3D Wound Core Transformers for its projects since 2017.For the Biel Crystal Hai Duong Plant, four big-capacity Open Ventilated 3D Wound Core Dry-type Transformers (three 16,000kVA/22kV units and one 2,500kVA/22kV unit) were deployed to build a green, energy-efficient, and highly reliable power distribution system, ensuring a stable energy supply for large-scale production. This initiative not only reflects Biel Crystal’s commitment to production safety and environmental sustainability but also highlights the leading position of China’s energy-saving transformer technology on the global stage, injecting new momentum into the high-quality development of the " the Belt and Road" initiative.

The Sinopec Guangzhou Baihedong Integrated Energy Station has adopted the Double-layer Double-transformer Substation manufactured by Haihong Electric to create Guangdong's first flagship integrated energy smart station. Recently, the station was selected for Guangzhou's first five-star rating list for public electric vehicle charging and battery swap stations. This project not only serves as a benchmark application of the Double-layer Double-transformer Substation in the charging station sector but also marks a new phase of collaboration between Haihong Electric and Sinopec, injecting fresh momentum into the high-quality development of urban charging infrastructure.

Recently, the Electrical and Automation Branch of the Guangdong Engineering Survey and Design Industry Association visited Haihong Electric for in-depth discussions on technological innovation in electrical equipment, industry development trends, and the diverse application scenarios of 3D wound core technology. As a global leader in 3D wound core transformer technology, Haihong Electric has consistently embraced open collaboration, actively integrating industry resources to drive energy efficiency upgrades and high-quality development in the electrical sector through continuous innovation and forward-thinking application solutions.
