Leilang Electric proudly presents our high-performance 1000KVA three-phase cast resin dry-type transformer, engineered for versatile grid compatibility across North America and global markets. This multi-voltage unit supports primary inputs from 4160V to 14400V while delivering a stable 480Y/277V secondary output, making it ideal for commercial buildings, industrial facilities, and data centers.

Featuring advanced AN/AF dual cooling systems and F-class (155℃) insulation, our transformers ensure reliable operation even under demanding load conditions. Backed by CE and ISO certifications, every unit undergoes rigorous quality testing to guarantee low energy loss, exceptional durability, and compliance with international safety standards.

Our 1000KVA cast resin transformers utilize high-quality silicon steel cores with anti-corrosion coatings, minimizing no-load losses to just 2200W and ensuring long-term energy efficiency. The high-voltage windings feature continuous drop-down disc construction with aluminum conductors and double-layer insulation, vacuum-cast in epoxy resin for maximum dielectric strength and mechanical stability.

Low-voltage windings are constructed from aluminum foil pre-impregnated with epoxy resin, cured in precision ovens to create compact, thermally efficient coils.

Designed as a true multi-tap transformer, this unit accommodates six standard primary voltage levels: 4160V, 7200V, 12470V, 13200V, 13800V, and 14400V. Off-circuit tap changers with a ±2*2.5% tapping range allow for precise voltage regulation, ensuring consistent power delivery regardless of grid fluctuations.

The Yyn0 vector group configuration provides balanced three-phase power with a neutral connection, suitable for both single-phase and three-phase loads.

Every Leilang Electric transformer is manufactured in our state-of-the-art facilities under strict ISO 9001 quality management systems. We implement comprehensive quality control measures at every production stage, from raw material inspection to final performance testing.

All units are certified to CE standards, demonstrating compliance with European safety, health, and environmental requirements. With a 24-month warranty from the bill of lading date and lifetime technical support, we stand behind the reliability of our products.
