顺特电气超大容量预装式变电站成功交付

In mid-2024, SUNTEN was awarded the "Shenyang 40MW Inverter Project" by Changzhou Borui Company. The project required two 10kV prefabricated substations, each equipped with 20,000kVA dry-type transformers without excitation voltage regulation. The system consists of two substations operating in parallel, making it currently the largest capacity prefabricated substation product in China.

Changzhou Borui Power Automation Equipment Co., Ltd. is an important process research center and primary equipment production base for NR Electric Co., Ltd. It is reported that this project will serve the Shenyang Aeroengine Research Institute (606 Institute) under AVIC, which is China's first aeroengine design institute primarily engaged in the design and development of large and medium-sized aircraft engines, as well as gas turbine R&D tasks.

The high-capacity prefabricated substation presented increased difficulties in both product design and manufacturing processes. The substation utilizes large-capacity dry-type transformers that require special lifting equipment for installation and three-phase high-capacity fans to ensure safe and normal operation. The product features a containerized enclosure that must meet structural strength requirements for a single substation weighing over 50 tons. Additionally, the customer had stringent requirements for the high and low voltage switchgear equipment in the substation. The product is equipped with fixed switchgear for high currents of 6-10kV, with rated currents exceeding 4000A, and the switchgear must provide intelligent protection, user-friendly operation, and digital monitoring capabilities.

Facing these challenges, various departments at SUNTEN worked closely together. The sales and R&D teams proactively addressed difficulties, actively cooperating with the design institute and customers to continuously optimize the design solutions, ensuring successful project execution. By mid-November, these two high-capacity prefabricated substations were successfully completed, with all performance parameters fully meeting customer requirements, and were delivered on schedule, providing reliable support for the customer's R&D project.

The prefabricated substation adopts a modular design concept, integrating multiple functional electrical equipment such as transformers, control systems, and protection devices into a compact, transportable containerized power distribution system. Traditional substation construction typically requires over a year, while SUNTEN's prefabricated substation can reduce this period to just a few months before being transported as a complete unit to the customer's site for immediate use. This new power system can significantly accelerate project timelines and improve operational efficiency for customers.

The successful development and on-time delivery of this ultra-high-capacity, complex prefabricated substation demonstrates SUNTEN's strong technological innovation capabilities and R&D problem-solving competence, highlighting the company's leading position in power industry solutions. Moving forward, SUNTEN will continue to uphold the corporate spirit of "Integrity and Trustworthiness, Pioneering Innovation, Collective Effort, and Pursuit of Excellence," strengthen technological R&D capabilities, further expand market reach, consistently provide high-quality products and services to customers, and work with partners to promote the construction of major projects.
