3D Wound Core Technology Empowers Green Airports: Haihong Electric Helps Chinese Airports Enter a New Low-Carbon Era

Under the guidance of China's "dual carbon" goals, green and low-carbon transformation has become a core direction for development across industries, and the civil aviation sector is accelerating its green transition. As energy-intensive infrastructure, the upgrading of airport power systems is crucial. Leveraging its innovative, energy-efficient transformers featuring advanced 3D wound core technology, Haihong Electric has provided highly efficient, safe, and reliable power solutions for multiple airports nationwide, supporting China's civil aviation industry in moving toward a green and low-carbon future.

High Efficiency and Energy Savings: Supporting Low-Carbon Airport Operations

As 24/7 operational hubs, airports have enormous electricity demands, making it imperative to address the high energy consumption of traditional power distribution equipment. Haihong Electric’s energy-saving innovations utilize world-leading 3D wound core transformer technology, which—compared to traditional laminated core transformers (at the same material cost)—reduces no-load losses by 30%, load losses by 5%, no-load current by 70%, and annual operating costs by 10%, significantly improving overall energy efficiency.

If amorphous alloy 3D wound core dry-type transformers are adopted, operational losses can be further reduced. In high-energy-consumption environments like airports, replacing outdated laminated core transformers with energy-efficient 3D wound core transformer can substantially cut energy use, lower electricity costs, and reduce carbon emissions, achieving both economic and environmental benefits.

High Safety and Reliability: Ensuring Stable Airport Operations

Airports are classified as Grade I power consumers, meaning their electrical systems demand extremely high safety and reliability from equipment. Transformers must have strong short-circuit resistance and adapt to complex operational conditions. The 3D wound core transformer series used in airport projects excels in short-circuit resistance. These transformers can also be equipped with intelligent monitoring systems to track real-time operating temperature, energy consumption, load conditions, and other critical metrics, enabling early fault detection and greatly improving power supply reliability.

Open ventilated 3D wound core dry-type transformers offer superior comprehensive performance. Their low-temperature rise operation, combined with moisture- and contamination-resistant designs, significantly enhances reliability, environmental adaptability, and durability. Additionally, these transformers are fire- and explosion-resistant, with an average of 85% less combustible material than traditional resin-insulated dry-type transformers, greatly improving fire safety and ensuring secure, highly reliable operation.

Miniaturized Double-layer Prefabricated Substations, equipped with open ventilated wound core dry-type transformers and modular independent functional chambers, provide higher safety and energy efficiency compared to older single-layer substations. The stainless-steel enclosure with anti-corrosion coating resists salty erosion and withstands extreme outdoor weather conditions.

Nationwide Airport Applications: Supporting the Development of Green Airports

3D wound core transformers have been deployed in power distribution systems at multiple airports across China, including Guangzhou Baiyun International Airport, Shanghai Pudong International Airport, Hangzhou Xiaoshan International Airport, Sanya Phoenix International Airport, Haikou Meilan International Airport, Shenzhen Airport, and Meizhou Airport. This technology helps reduce energy consumption in airport power systems, providing robust support for green transformation and contributing to the national goal of "increasing capacity without increasing carbon emissions."

Guided by China’s "dual carbon" strategy, Haihong Electric leverages its core technological strengths to deliver green power solutions for critical infrastructure like airports, driving the industry toward greater efficiency, sustainability, and intelligence. The widespread adoption of 3D wound core transformers and miniaturized double-layer prefabricated substations represents not only a technical breakthrough but also a commitment to sustainable development.
