Experience, Capability, and Delivery
Experience
Our team includes electrical engineers with experience in the U.S. power industry. They provide customized design solutions for customers and help our manufacturing partners in China understand U.S. requirements, so products meet IEEE, ANSI, and NEMA standards. We also provide U.S.-based service, and our China operations bring over 30 years of experience in the U.S. market.
Capability
Sino Power Dynamics works with three production bases in China, each manufacturing a different class of electrical product: Sanbian Technology (35kV to 550kV), Changzhou Pacific (35kV to 220kV transformers and switchgear), and Shuangxin (35kV to 110kV distribution transformers).
Delivery
Production capacity has increased significantly, improving delivery times: about 3.5 months for 550kV units, 3 months for 35kV to 220kV units, and 1 month for distribution transformers. In 2024, capacity was expanded with a new factory at Shuangxin, along with larger reserves of core materials such as silicon steel.
Product lines
Sino Power Dynamics offers two main product lines. Switchgear is also available through our manufacturing network.
Distribution Transformers
35kV – 110kV
Dry-type, cast-resin distribution transformers, manufactured at our Shuangxin production base.
