Haihong Electric's Prefabricated Substation for Energy Storage Shines at 2026 Smart Energy Week in Japan. With outstanding technological expertise and forward-looking product design, it garnered extensive attention and high recognition in the international market.
Innovative Product Makes Brilliant Debut, Excellent Performance Earns Acclaim
At this exhibition, Haihong Electric highlighted its Prefabricated Substation tailored for energy storage scenarios. The product can be flexibly configured with a 3D Wound Core Dry-type Transformer or a 3D Wound Core Oil-Immersed Transformer, fully meeting the diverse requirements of different projects.
Exhibition Appearance Leads to Immediate Implementation! The displayed enclosure substation will be put into operation immediately after the exhibition at the Omuta City Energy Storage Power Plant in Japan.
Addressing Japan's marine climate with high salt mist and high humidity, Haihong Electric implemented a specialized anti-corrosion design for the product: the enclosure of the Prefabricated Substation and the tank of the oil-immersed transformer both utilize stainless steel housing and anti-corrosion coating processes. If the 3D Wound Core Dry-type Transformer is selected, it can completely eliminate risks of enclosure corrosion and oil leakage, ensuring long-term stable operation of the equipment, truly achieving adaptability to local conditions and reliable quality.
In terms of performance, Haihong Electric's 3D wound core transformers feature lower losses, with measured values exceeding Japan's energy conservation standards. Leveraging the comprehensive advantages of a stable core structure, excellent insulation performance, and low noise, they provide a safer, more reliable, more energy-efficient, and environmentally friendly power distribution solution for Japan's energy storage system construction.
Deepening Presence in the Japanese Market, Winning Reputation Through Practical Projects
In recent years, the number of photovoltaic and energy storage projects in Japan has continued to rise, creating an urgent market demand for efficient and reliable power distribution equipment. The anti-corrosion performance and power distribution effectiveness of Haihong Electric's products have been validated in various projects:
The first 2MW/8MWh energy storage power station in a certain city in Fukuoka Prefecture, Japan, adopted Haihong Electric's Prefabricated Substation for energy storage. It has won high praise from users and the industry due to its significant energy-saving effects, ultra-low operating noise, and exceptional stability.
Fukuoka Prefecture Energy Storage Project
Facing the extreme high salt mist corrosion environment on Miyakojima, Japan, the Haihong enclosure substation (equipped with a 3D Wound Core Dry-type Transformer) was put into operation in 2019, successfully overcoming the challenge of island corrosion and achieving long-term stable operation.
Miyakojima Solar Power Project
Phase II of the Hamada MS Solar Power Station project in Japan adopted Haihong Electric's power distribution equipment. Compared to Phase I, the average power generation increased by 9%, costs decreased by 20%, and the economic benefits were significant. Additionally, the noise level was much lower than that of the Phase I equipment, resolving the issue of disturbance to residents.
Hamada Phase II Solar Power Project
Leveraging the strong technological capabilities of its 3D wound core transformers, Haihong Electric has gained extensive recognition in the Japanese market. Through this exhibition, Haihong Electric not only showcased the technological expertise of Chinese enterprises in the green energy sector to the world and further enhanced the influence of 3D wound core technology in the Japanese market, but also enabled China's energy-saving transformer technology to shine brightly on the international stage. In the future, Haihong Electric will continue to uphold an attitude of open cooperation, contributing Chinese wisdom and solutions to the high-quality development of the global energy storage and power distribution sector with better products and services.
