What is a power transformer?

Power transformers are electrical instruments used in transmitting electrical power from one circuit to another without changing the frequency.

High-voltage transformer,use Japanese Toshiba analysis software and our company special calculation and validation procedures to the transformer core,winding, structural components, lead, fuel tanks, etc. Parts of the optimal design and carry on the omni- directional validation, ensure product performance.

Superior process equipment,elaborate material selection and efficient manufacturing,resulting in a transformer with a small volume, light weight,low loss,low-partial-discharge, low noise characteristics,the product quality is superior, energy conservation and environmental protection, easy installation and maintenance, reliable operation and effectively reduced products running costs.

Our product SSZ20-240000/220 has passed the short-circuit withstand capacity and all routine type tests of the National Transformer Quality Supervision and Inspection Center.

This product is stable,reliable,economical and environmentally friendly, and is suitable for power plants, substations, large industrial and mining petrochemical enterprises,etc.
