Dry Type Transformer Product Description (35kV and Below)
D ry type transformer is an environmentally friendly, non-flammable, and maintenance-free power distribution device designed for applications up to 35kV. Unlike oil-filled transformers, dry type transformers utilize advanced solid insulation materials such as epoxy resin or vacuum pressure impregnation (VPI) technology, ensuring exceptional safety, reliability, and compliance with modern energy efficiency standards. Below are the key features and advantages of dry type transformers rated for 35kV and lower voltage systems:
1. Core Design & Insulation
- Dry type transformers employ high-grade silicon steel cores with low loss characteristics, minimizing no-load losses and operational costs.
- Encapsulated or open-wound insulation systems provide superior resistance to moisture, dust, and thermal stress, ensuring stable performance in harsh environments.
2. Cooling Mechanism
- Natural air cooling (AN) or forced air cooling (AF) eliminates the need for flammable liquids, making dry type transformers ideal for indoor installations (e.g., commercial buildings, hospitals, data centers).
3. Safety & Environmental Benefits
- Flame-retardant and self-extinguishing materials reduce fire hazards, meeting IEC 60076-11 and IEEE C57.12.01 standards.
- Zero risk of oil leaks or toxic emissions, contributing to sustainable infrastructure.
4. Applications
- Dry type transformers are widely used in:
- Renewable energy systems (solar/wind farms).
- Industrial plants requiring explosion-proof equipment.
- Urban power grids and underground substations.
- Critical facilities where fire safety is paramount.
5. Energy Efficiency
- Compliant with IE3/IE4 efficiency classes (per IEC 60076-20), reducing carbon footprint and lifecycle costs.
6. Customization Options
- Available in multiple configurations: cast resin, vacuum pressure encapsulated, or encapsulated coil designs.
- Optional IP54/IP55 protection ratings for dust- and water-resistant operation.
7. Installation & Maintenance
- Compact, lightweight structure simplifies installation.
- Minimal maintenance requirements due to robust dry type transformer architecture. Periodic thermal imaging and insulation checks ensure longevity.
8. Standards Compliance
- Certified to global standards: IEC, IEEE, UL, and CE.
Why Choose a 35kV Dry Type Transformer?
