⚡ Product Description
2500kva Power Distribution Amorphous Alloy Dry-Type Transformer

A dry type transformer, also known as an air-cooled transformer, utilizes air or gas instead of liquid (such as oil) for insulation and cooling purposes. This design does not immerse its core and windings in insulating oil, making it distinct from oil-filled transformers.

Types of Dry Type Transformers

Cast Resin Dry Type Transformer (CRT)
  • Uses epoxy resin to encapsulate windings for protection from moisture, dust, and corrosion.
  • Suitable for high humidity areas and fire-risk zones.
  • Ratings from 25 kVA to 12,500 kVA.
Vacuum Pressure Impregnated Transformer (VPI)
  • Impregnates windings with class H polyester resin under vacuum.
  • Enhances mechanical strength and thermal stability.
  • Ideal for outdoor installations and seismic events.

❓ Frequently Asked Questions
1. What is the difference between CRT and VPI dry-type transformers? Cast Resin (CRT) uses epoxy resin to fully encapsulate windings, making it ideal for high-humidity and fire-risk areas. VPI uses polyester resin under vacuum for better mechanical strength and thermal stability, often used in outdoor or seismic-prone areas.
2. What international standards do your transformers comply with? Our transformers are designed and manufactured in accordance with IEC 60076 standards and have achieved CE, UL, and KEMA certifications.
3. Can the tapping range be customized? Yes, we offer a standard tapping range of ±2×2.5% with options for both Off-Circuit Tap Changer (NLTC) and On-Load Tap Changer (OLTC) based on customer requirements.
4. What are the main materials used for the core and windings? We utilize high-quality Silicon Steel for the transformer core and 100% Copper for the windings to ensure maximum efficiency and durability.
5. What is the typical production lead time? In general, production takes approximately 4 to 6 weeks, depending on the specific transformer configuration and design requirements.
6. How is the cooling of these dry-type transformers managed? The transformers can be cooled using Natural Air (AN) or Forced Air (AF) methods, with optional cooling fans and temperature control sensors for enhanced protection.
