OUR PRODUCTS
YG specialize in manufacturing various types of power transformer,including oil immersed transformers, dry type transformer,pad mounted transformers and compact transformers,of which the rated voltage covers 6 kV,10 kV,11 kV,15 kV,33 kV,35 kV, and the rated power ranges from 30 kVA to 20000 kVA.Through 10 years’ continous concentrate on develping the balance between quality and price, we have grown to be one of the leading power transformer factories in China.






Who We Serve
Our equipment goes into projects where downtime is expensive and grid connection dates are fixed. We work to the documents those projects run on — drawings, test schedules and inspection releases.
EPC Contractors
Transformer, compact substation and switchgear supplied as one package, with drawing submittals and inspection coordination handled against your project schedule.
Electrical Engineering Companies
We build to your specification rather than asking you to accept ours: vector groups, impedance values, tap ranges and protection interfaces reviewed before quotation.
Utility Companies
Oil-immersed and dry-type units manufactured to IEC 60076, GB 1094 and IEEE C57, with routine and type testing documented for utility approval.
Renewable Energy Developers
Inverter step-up and collector substation transformers for solar and wind plant, sized for cyclic loading and grid connection requirements.
Industrial Power Projects
Unit substations and cast-resin dry-type transformers for plants and other continuous process sites where fire rules, indoor space or layout decide the design.
