1. Basic Parameters: Core Specifications of 2000kVA Dry-Type Transformers

1.1 Rated Capacity

• The 2000kVA dry-type transformer is suitable for medium- and high-voltage power distribution systems, commonly used in industrial, commercial, and renewable energy applications.

1.2 Voltage Levels

• Typical configurations:
  • 10kV/0.4kV (distribution transformer)
  • 35kV/10kV (step-up/step-down transformer)
  • Customizable for special requirements (e.g., 6.6kV, 20kV).

1.3 Insulation Class

• Class F (155°C): Suitable for most industrial environments.
• Class H (180°C): For high-temperature environments or applications requiring high overload capacity.

1.4 Short-Circuit Impedance (Uk%)

• Standard values: 6%, 8% (affects short-circuit current withstand capability).
• Adjustable between 4%~10% for special applications (e.g., data centers).

2. Structural Features: Design Advantages of 2000kVA Dry-Type Transformers

2.1 Epoxy Resin Casting Technology

• Dry-type transformers use vacuum-cast epoxy resin for high mechanical strength and moisture resistance.
• Unlike oil-immersed transformers, they eliminate oil leakage risks, making them ideal for fireproof and explosion-proof environments (e.g., subways, hospitals).

2.2 Temperature Rise Limit

• Standard temperature rise: 100K (Class F insulation).
• Overload capability: Can operate at 110% load for short durations.

2.3 Cooling Methods

• AN (Natural Air Cooling): Low noise, suitable for indoor power distribution rooms.
• AF (Forced Air Cooling): Equipped with fans to enhance overload capacity.

3. Performance Advantages: Why Choose a 2000kVA Dry-Type Transformer?

3.1 Safety and Environmental Benefits

• Fireproof and explosion-proof: Oil-free design, ideal for high-safety environments like high-rise buildings and data centers.
• Pollution-free: Complies with RoHS standards, free of hazardous substances like PCBs.

3.2 High Efficiency and Energy Savings

• No-load loss: Approximately 2.5kW~3.5kW (SCB13 efficiency class).
• Load loss: Approximately 15kW~20kW (depends on copper/aluminum windings).

3.3 Low Maintenance Costs

• Oil-free design eliminates oil filtration and replacement maintenance.
• Optional smart monitoring (temperature sensors, partial discharge detection).

4. Compliance Standards: International and Domestic Certifications

• International Standards: IEC 60076, IEEE C57.12.01
• Chinese Standards: GB/T 1094.11 (National Standard for Dry-Type Transformers)
• Efficiency Classes: SCB13 (Tier 2 efficiency), SCB18 (Tier 1 efficiency)

5. Application Scenarios

✅ Industrial Sector: Steel plants, chemical plants (high-temperature and corrosion resistance).
✅ Commercial Buildings: Hospitals, airports (high fire safety requirements).
✅ Renewable Energy: Solar farms, wind farms (suitable for frequent start-stop operations).
