/ 1 / 1
Power Transformer
Power transformer is a core power system device that converts AC voltage to match transmission/distribution/use, ensuring efficient and stable grid operation.
/ 2 / 2
Distribution Transformer
Used in power systems, the transformer box realizes voltage conversion, safeguards internal components, and supports reliable power supply.
/ 3 / 3
Transformer Box
Essential for substations, the substation transformer adjusts voltage, facilitates efficient electricity transfer, and supports steady power grid performance.

EV Charging Station
EV charging station offers safe, efficient fast/slow charging to electric vehicles, facilitating their smooth daily operation and travels.
What’s Your Power Challenge? We Have the Fix

Low-Loss Transformers – Cut Energy Bills by 10-15%
Standard transformers waste 3-5% of energy as heat. Our high-efficiency designs reduce this to <2% via: Ultra-thin silicon steel cores (lower eddy current loss), Optimized copper windings (minimized resistance), Smart cooling that adjusts to load demands.
