Three-Phase Dry-Type Transformer

Key 2025 specifications include:

Voltage Range: 400V to 34.5kV (IEEE C57.12.01-2025 compliant)

Capacity: 25kVA to 20MVA, with ±2% voltage regulation

Efficiency: Up to 99.3% at 50% load (meeting EU Tier 3 Ecodesign 2025/178 standards)

Temperature Class: F/H (155°C/180°C) insulation, rated for -25°C to +45°C ambient

Protection: IP55 ingress protection, 150kV BIL (Basic Insulation Level), and integrated IoT thermal sensors for real-time monitoring.

Widely used in data centers, renewable energy grids, and smart factories, modern variants feature nanocrystalline cores for 25% lower losses and modular designs enabling rapid upgrades under NEC 2025 safety codes.
