Daqo Supplies Transformers for BYD Chengdu New Energy Vehicle Industrial Project

As the global automotive industry accelerates its transition toward electrification, new energy vehicles (NEVs) are becoming a major driving force for industrial transformation. Leading electric vehicle manufacturer BYD is actively expanding its production capacity and building large-scale manufacturing ecosystems across China. Among these strategic developments, the BYD Chengdu New Energy Vehicle Industrial Project stands out as a key milestone in the company’s plan to create a trillion-level industrial cluster for electric vehicles, batteries, and semiconductor technologies.

The Chengdu project integrates electric vehicle manufacturing, battery production, research and development centers, and supporting industrial infrastructure, forming a comprehensive new energy vehicle ecosystem. This large-scale industrial base not only supports BYD’s rapidly growing production capacity but also aligns closely with Chengdu’s long-term economic development strategy focused on high-tech manufacturing and green energy industries.

To ensure stable and efficient power distribution across the production facilities, Daqo Transformer provided a complete dry type transformer solution for the project. A total of 94 dry type transformers were supplied for the power infrastructure of the BYD Chengdu plant and its auxiliary systems, with a total project value of USD 3.219 million. These transformers play a critical role in supporting the reliable electrical supply required for large-scale EV manufacturing operations.

Reliable Power Infrastructure for EV Manufacturing

Modern electric vehicle factories require highly stable and efficient power systems to support complex production processes such as battery assembly, motor manufacturing, automated production lines, and testing facilities. The industrial power distribution transformers supplied by Daqo Transformer ensure consistent voltage conversion and energy distribution across the entire factory.

The project primarily utilizes SCB14 series cast resin dry type transformers, which are widely recognized for their high safety performance, environmental protection, and energy efficiency. These transformers are particularly suitable for indoor installations in manufacturing plants, where fire safety, reliability, and low maintenance are essential.

Dry type transformers eliminate the risks associated with oil-filled transformers, such as oil leakage and fire hazards. Their air-cooled design provides stable operation while minimizing maintenance requirements, making them ideal for industrial production environments and EV manufacturing facilities.

Supplied Transformer Models

The project includes several models of medium voltage to low voltage dry type distribution transformers, designed to meet the specific electrical load requirements of different areas within the factory.

Partial list of supplied models includes:

SCB14-2500/20/0.4 (6% impedance)
SCB14-2500/20/0.4 (8% impedance)
SCB14-1600/20/0.218
SCB14-3150/20/0.4/0.5

These SCB14 cast resin transformers are designed for high-efficiency power distribution and stable operation under demanding industrial loads. With capacities ranging from 1600 kVA to 3150 kVA, they provide reliable energy conversion from the medium voltage grid to low voltage systems used by production equipment and facility infrastructure.

In total, more than 90 dry type transformers were delivered and installed to support the electrical system of the BYD Chengdu manufacturing base.

Advantages of SCB14 Dry Type Transformers

The SCB14 series dry type transformer offers several advantages that make it suitable for modern industrial projects and new energy manufacturing facilities.

High safety performance

These transformers use cast resin insulation technology and contain no flammable oil, significantly reducing fire risks and ensuring safe operation in enclosed factory environments.

Energy-efficient design

The SCB14 transformer series features optimized core materials and advanced winding structures that reduce no-load and load losses, improving overall energy efficiency.

Environmentally friendly operation

Dry type transformers produce no oil leakage or harmful emissions, supporting environmentally responsible industrial development.

Low maintenance requirements

Compared with oil-filled transformers, dry type transformers require less routine maintenance, reducing operational costs and downtime for industrial facilities.

Compact structure and flexible installation

The compact design of dry type transformers allows easy installation in power distribution rooms within factories, helping optimize space utilization in manufacturing plants.

Supporting the Development of the EV Industry

The BYD Chengdu project represents a significant step in strengthening China’s global leadership in the new energy vehicle industry. By integrating manufacturing, research, and supply chain ecosystems, the project contributes to the rapid development of electric vehicles and related technologies.

Reliable power infrastructure is essential for supporting such large-scale industrial operations. The dry type transformers supplied by Daqo Transformer ensure that the EV manufacturing base operates with stable, safe, and efficient electrical systems.

In addition to supporting production capacity, the project also contributes to regional economic growth, job creation, and technological innovation in Chengdu and the surrounding areas. The development of new energy vehicle industrial clusters further enhances the competitiveness of China’s green manufacturing sector in the global market.

Conclusion

The successful delivery of more than 90 SCB14 dry type transformers for the BYD Chengdu New Energy Vehicle Industrial Project demonstrates Daqo Transformer’s capability in providing reliable power distribution solutions for large-scale industrial applications.

With their safety, efficiency, and environmental advantages, dry type transformers are becoming an essential component in modern manufacturing facilities, especially within the rapidly expanding electric vehicle and renewable energy industries.

By supporting critical infrastructure for EV production, this project not only strengthens BYD’s manufacturing capabilities but also contributes to the advancement of sustainable transportation and clean energy technologies worldwide.
