Dry-type transformer
After over 30 years of innovation, we have formed a full series of dry-type transformer product lines, including SC to SCBH19 iterative models, as well as new energy equipment such as 1,500V energy storage systems. Prefabricated substation
Prefabricated substations are fully functional, reliable, with low investment, small footprint, and easy installation; they have good safety and a wide range of enclosure types. Pad-mounted transformers
In 1999, the company was the first in China to introduce the complete set of the most advanced design, process and manufacturing technology from GE in the United States, and successfully developed pad-mounted transformers with a compact structure and small size. Liquid-immersed transformers
Liquid-immersed transformers utilize a highly stable insulating liquid medium, and achieve efficient power transmission through electromagnetic induction between the iron core and windings. Reactors
Since the early 1990s, relying on the “Guangdong Provincial Urban Network Electrical Equipment Engineering Technology Development Center”, SUNTEN has developed and researched resin-insulated dry-type air-core reactors and dry-type iron core reactors. Grounding systems
In the late 1990s, SUNTEN developed an automatic tuning arc suppression coil grounding complete set that integrates primary high-voltage equipment and secondary control equipment. Switchgears
Since 2002, SUNTEN has been producing complete switchgear sets, with products covering the full range of 400V-40.5kV/400A-6300A, and having authorized cabinet models of Schneider MVnex+BlokSeT and ABB MDmax. Energy storage
SUNTEN (founded in 1988) is a leading enterprise in the field of power transmission and distribution, as well as new energy equipment, with core technologies in areas such as thermal power frequency regulation energy storage, wind-solar-storage integration, and industrial and commercial energy storage. -

High Technical Difficulty & Strict Quality Control
The Three Gorges Project has extremely high requirements for the reliability, efficiency, and safety of electrical equipment. Sunten had to ensure the stable operation of dry-type transformers under extreme conditions. At the same time, the project has strict requirements for equipment quality, requiring multiple certifications and on-site installation and commissioning to ensure the products meet standards.
Large-Scale Supply & Delivery Pressure
The Three Gorges Project is massive in scale, with large equipment demand and complex specifications. Sunten had to ensure quality while completing large-scale production and delivery on time, facing tight schedules and supply chain management challenges.
Demanding Environmental Adaptability Requirements
The Three Gorges Project is located in the Yangtze River basin with a humid climate, so the equipment needs excellent anti-moisture and anti-corrosion performance. Furthermore, the project requires long-life, low-maintenance equipment, which needs to be fully met in the design and manufacturing.

Achievements
In 1999, Sunten Electric’s R&D team formulated customized technical parameters for the Three Gorges Hydropower Station, conducting groundbreaking studies including:
Rectifier harmonic analysis for excitation systems
Additional loss quantification
Temperature-rise simulation experiments
In just 9 months, Sunten delivered the equipment a year ahead of schedule with high quality, and the performance and technical indicators reached the international advanced level.
This filled a domestic technological gap and laid the foundation for the localization of excitation transformer equipment for the Three Gorges Power Station. Sunten also collaborated with Siemens and won the bid for the excitation system project of the Three Gorges Power Station’s left bank, becoming the only domestic equipment supplier.
Enduring Impact
SUNTEN has partnered with the Three Gorges Corporation to supply dry-type excitation transformers for hydropower stations such as Baihetan, Xiluodu, Wudongde, and Xiangjiaba. In 2021, when the Baihetan Hydropower Station began operation, SUNTEN secured the entire transformer order, supplying nearly 30 transformers. SUNTEN has established a leading position in the power transformers for hydropower plant applications. From the Three Gorges to Baihetan, SUNTEN has consistently driven the localization of equipment, helping China’s hydropower industry transition from a “follower” to a “leader”.
