Power Transformer

(Total 18 Products)

Our company is a professional Power Transformer manufacturer with over 36 years of manufacturing experience, originating from a special Transformer factory in China. We mainly design and produce electric furnace transformers and rectifier transformers, covering up to 110KV high-grade models widely applied in metallurgy, mining and industrial power supply fields.
All Power Transformers adopt high-flux, low-loss silicon steel sheets from Wuhan Iron and Steel, combined with patented coil structure and low-leakage terminal technology. Compared with peer products, our transformers feature lower temperature rise below 45℃, lower running noise, 10%-20% no-load loss reduction and 5%-10% lower load loss. They also own lower impedance voltage, higher power factor, strong overload capacity and excellent short-circuit resistance.
Certified with ISO9001, ISO14001 and CQC, we hold more than 20 national patents. All power transformers pass authoritative technical appraisal, delivering stable, energy-saving, eco-friendly and cost-effective solutions for global industrial B-end buyers.
