Why Choose Unicore

Your Trusted Partner in Power Solutions

We are a National High-Tech Enterprise in China. Our main products include 500kV, 400kV, 330kV, 220kV and 110kV high-voltage power transformers; various dry-type transformers, oil-immersed transformers and amorphous alloy transformers rated 35kV and below; new energy transformers; and prefabricated substations.

Our 10kV and 35kV distribution transformers and compact substations have obtained international certifications including IEC certification, UL certification in the United States, TÜV certification in Germany, CE certification in the European Union, KEMA certification in the Netherlands, and GOST certification in Russia.

Our products are sold to more than 80 countries and regions across Asia, Africa, Europe, the Middle East and Latin America.

Full Tailor-Made Solutions

Voltage, capacity, frequency, winding material — every parameter is engineered to your exact specification, not adapted from a standard catalogue.

Meet Full Industry Standards

Every transformer leaves our factory with full test documentation — IEC, IEEE, ISO, and CE, so your procurement and engineering teams can move forward without delays.

Built Around Your Project

Full Customization of Unicore Transformers

Voltage & Capacity

From low-voltage distribution to extra-high voltage transmission, we engineer any primary/secondary ratio and MVA rating — precisely matched to your grid requirements and load conditions.

Core & Winding Material

We work with CRGO silicon steel cores and offer both copper and aluminium windings, giving you the flexibility to balance performance, weight, and budget without compromising on efficiency.

Frequency & Phase

Whether your grid operates at 50 Hz or 60 Hz, and whether your application requires single-phase or three-phase configuration, we engineer to your exact network standard.

Full Project Scope

Beyond the transformer itself, we provide complete power solution packages — from engineering design to full system coordination — tailored to the specific demands of your site and project timeline.
