Product Description
Dry Type Transformers for Data Centers
Mission-critical power distribution solution designed for 24/7 operation with fire safety and high reliability.
Overview
Modern data centers require continuous, stable, and safe power supply to support mission-critical IT infrastructure. Our Dry Type Step Down Transformers (315kVA / 400kVA / 630kVA) are purpose-built for data center power distribution, ensuring maximum reliability, zero oil-related risk, and long-term operational stability.
With oil-free insulation, low partial discharge design, and high thermal endurance, these transformers are ideal for indoor MV/LV rooms, UPS systems, PDUs, and modular data centers.
Why Dry Type Transformers Are Preferred in Data Centers
Unlike conventional oil-immersed transformers, dry type transformers eliminate fire and leakage risks, allowing installation closer to IT loads, reducing power losses and improving overall efficiency.
Key reasons data centers choose dry type transformers:
- No oil, no fire hazard
- Indoor installation capability
- High reliability under continuous load
- Minimal maintenance requirement
- Compliance with international data center standards
Core Design Highlights
- Cast Resin or VPI Dry-Type Insulation - High dielectric strength with excellent resistance to humidity and dust
- Copper or Aluminum Windings - Copper for lower losses and higher efficiency; Aluminum for optimized cost-performance
- Low Partial Discharge Design - Suitable for sensitive servers and IT equipment
- Advanced Thermal Design - Continuous full-load operation with optional forced air cooling (AF) for overload scenarios
- Low Noise Operation - Ideal for indoor technical rooms
