Cast Resin Dry Type Transformer

Cast Resin Dry Type Distribution Transformers are engineered for reliable performance in industrial and power distribution applications. Available in capacities from 630kVA to 3150kVA, these three-phase units feature cast resin insulation for superior fire resistance, low maintenance, and suitability for indoor or high-altitude installations. Designed to meet international standards, they deliver stable power conversion for factories, data centers, and commercial buildings.

Technical Features & Components

Advanced Insulation System

Epoxy resin dry-type transformers are designed for indoor installation. Their cooling methods include natural air cooling (AN) and forced air cooling (AF). With forced air cooling, output capacity can increase by up to 50%, making it suitable for intermittent overload operation or emergency requirements.

High-Temperature Resistant Coil

Advanced materials enable resistance up to 150 °C. The high-quality insulation offers superior electrical properties and longevity even in tough environmental conditions.

High-Permeability Core

The core uses low-loss design and high-permeability materials to reduce excitation current and noise. Excellent thermal stability allows for wide-temperature operation with high mechanical strength.

Cross Flow Cooling Fan

Installed adjacent to the windings, these fans direct air across a wide heat-dissipation area, accelerating air movement and preventing component overheating for stable long-term operation.

Key Advantages

Safe, fireproof, and pollution-free for direct use in load centers.

High mechanical strength and strong short-circuit resistance.

Low loss, low noise, and maintenance-free design.

Excellent heat dissipation with strong overload capacity.

Moisture-proof performance adapted for high-humidity environments.

Intelligent signal temperature control system for 3-phase winding monitoring.
