Recently, the Terminal 3 (T3) building of the Sanya Phoenix International Airport Phase III Expansion Project (hereinafter referred to as the “Phoenix Phase III Project”) successfully passed its completion acceptance, marking the project’s full transition into the acceptance and commissioning preparation stage. As a landmark expansion project during the “14th Five-Year Plan” period of Hainan’s civil aviation and a key pilot project in the construction of the Hainan Free Trade Port airport cluster, the T3 terminal was completed in less than 18 months from groundbreaking to completion — setting the fastest construction record among terminals of similar scale in recent years.
CEEG supplied 26 units of SCBH17 amorphous alloy dry-type transformers for the project, providing safe, efficient, and environmentally friendly power support for the terminal and parking facilities. These transformers help ensure stable power supply for the airport’s complex, high-load, and round-the-clock operations.
一、Continuous and Stable Power Supply under High-Load Conditions
The Terminal 3 (T3) building of the Phoenix Phase III Project covers a total construction area of approximately 120,000 square meters and is designed to handle 18 million passengers per year. The terminal consists of three floors above ground and one underground level, equipped with 40 check-in counters, 23 security checkpoints, and 15 boarding bridges. With systems such as air conditioning, lighting, elevators, passenger boarding bridges, baggage handling, monitoring, and dispatching operating at high power over extended periods, the electrical load is both concentrated and subject to frequent fluctuations. Meanwhile, Sanya’s humid and high-temperature marine climate imposes stricter requirements on the transformers’ insulation, moisture resistance, heat dissipation, and noise control performance.
二、Multi-Capacity Coverage for a Highly Efficient and Coordinated Energy System
The T3 terminal of the Phoenix Phase III Project adopts a zonal power distribution system with multi-level redundancy design to meet the energy supply requirements of a large transportation hub operating 24/7 under high-load conditions. CEEG supplied 26 units of SCBH17 amorphous alloy dry-type transformers, covering capacities from 630 kVA to 2000 kVA, forming the core power supply system for both the terminal and the parking facilities. Through a system structure that combines independent operation with mutual backup, the design enables coordinated power supply between critical and auxiliary areas.
It not only ensures the continuous power supply of core equipment but also enhances the system’s operational reliability and maintenance flexibility. In the long-term operation, it effectively reduces energy losses, improves power supply efficiency, and provides technical support for the airport’s energy-saving and carbon-reduction goals.
三、Energy Efficiency and Performance Enhancement: SCBH17 Amorphous Alloy Dry-Type Transformers
To address Sanya’s high-temperature, high-humidity, and continuous high-load operating conditions, CEEG’s SCBH17 series amorphous alloy dry-type transformers deliver outstanding energy efficiency, strong protection, and intelligent features. These capabilities fully meet the strict requirements of large civil aviation hubs for safety, energy conservation, and stable operation.
1.High-Efficiency Amorphous Alloy Core
The transformer adopts an amorphous alloy core, reducing no-load losses by 60%–80% compared to traditional silicon steel transformers, significantly improving operational efficiency. For the terminal’s main power units, this translates to annual electricity savings exceeding 400,000 kWh, equivalent to a reduction of approximately 350 tons of CO₂ emissions per year (based on 0.88 kg CO₂/kWh), delivering measurable energy-saving results that support the airport’s low-carbon operation.
2. Weather-Resistant Insulation System
Using DuPont Nomex® aramid paper and an H-class insulation system with a thermal endurance of up to 220°C, the transformers offer excellent dustproof, moisture-resistant, and salt-fog protection. They can operate reliably over long periods in humid coastal environments, effectively reducing insulation aging and the risk of equipment failure.
3. Intelligent and Low-Noise Operation
Through optimized magnetic circuits and damping structures, the transformers operate with average noise levels well below national standards. Each unit is equipped with an intelligent temperature control and partial discharge monitoring system, enabling real-time monitoring of key parameters such as temperature rise, load, and partial discharge. This supports predictive maintenance and remote visualized management, providing a higher level of operation and maintenance assurance for the airport’s energy system.
四、Aesthetic Evolution: Infusing Industrial Design with Warmth and Beauty
In recent years, CEEG has been continuously exploring the balance between functionality and aesthetics in industrial design. Through a brand-new exterior design system, the company has given its transformers a more futuristic and scene-adaptable visual language. From the technological metallic texture and modular structural lines to the user-friendly visual monitoring interface and optimized heat dissipation layout, every detail reflects CEEG’s pursuit of modern industrial aesthetics. In contemporary settings such as airports, data centers, and commercial complexes, CEEG’s transformers not only deliver outstanding performance but also embody a unique sense of industrial beauty.
In the Phoenix Phase III Project, the project leaders highly praised the appearance design and manufacturing craftsmanship of CEEG’s equipment—an acknowledgment that stands as the highest recognition for the project team.
五、Building Trust Through Quality, Empowering the Industry Through Strength
The successful delivery of the Phoenix Phase III Project further demonstrates CEEG’s long-standing expertise in green and low-carbon solutions, intelligent operations and maintenance, and highly reliable power supply. With years of deep experience in civil aviation power systems, the company has provided power equipment and system solutions for numerous national and regional hub airports, including Beijing Daxing International Airport, Beijing Capital International Airport, Nanchang Changbei International Airport, Chengdu Shuangliu International Airport, Nanjing Lukou International Airport, Zhengzhou Xinzheng International Airport, Shijiazhuang Zhengding International Airport, Xianyang International Airport, and Guangzhou New Baiyun International Airport. Through these projects, CEEG has accumulated comprehensive experience in providing full-scenario power supply solutions, covering both major trunk-line airports and regional feeder airports, establishing a track record of reliability and industry leadership.
CEEG’s participation in the construction of Sanya Phoenix International Airport Terminal 3 not only continues the company’s stable cooperation in the civil aviation sector but also further validates the performance of its products in high-reliability and high-efficiency scenarios. Looking ahead, CEEG will continue to pursue its mission of “delivering premium power to the world”, leveraging high-quality products and forward-looking technologies to provide more efficient and sustainable power solutions for smart cities, clean energy, and transportation infrastructure.
