Product Details

Product Features

Sturdy Structure & Strong Impact Resistance

The high and low voltage clamps are integrally tightened with steel strips, upper beams and side beams to form a rigid frame structure, which significantly enhances the core clamping force and effectively improves the product’s resistance to transportation impacts.
Excellent Short-Circuit Withstand Capability

The product structure and winding design fully consider the bearing capacity of short-circuit electrodynamic force, featuring outstanding safety and stability.
Superior Heat Dissipation Performance

Longitudinal oil ducts are arranged in the high and low voltage coils, strengthening oil circulation and heat exchange efficiency. This greatly reduces the temperature difference between copper and oil as well as the hot-spot temperature rise inside the coils, improving reliability under overload and long-term operation.
Leading Performance Indicators

Boasts advantages including low loss, low noise and aesthetic appearance, with overall technical level meeting the advanced international standards of similar products.
Authoritatively Verified & Reliable Quality

The prototype of our company’s SZ13‑20000/35 transformer has passed the sudden short-circuit test conducted by the National Transformer Testing Center in one trial, obtaining authoritative certification for product quality and reliability.
