Oil Type Transformers
Oil
transformers use oil for insulation and cooling, helping maintain optimal
temperatures and preventing arcing. They are suitable for outdoor installations
in aggressive environments and come in hermetic and non-hermetic types.
Specifications
- Power: Up to 6,300 kVA
- Voltage Class: Up to 36 kV
- Core: CRGO or amorphous
- Winding Material: Aluminum or copper
- Cooling: ONAN, ONAF, OFWF, ODWF, ODAF
- Oil Types: Mineral, vegetable, silicone, or Midel 7131
- Ambient Temperature: -60°C to +60°C
Key Features
- Resistant to harsh environmental conditions
- No insulation level limits
- Excellent resistance to resonant overvoltages
Dry Type Transformers
Dry type transformers
use air or solid insulation instead of oil, making them suitable for
environments that require fire safety and have environmental concerns. Models
include E2, C2, F1, E3 (IEC 60076-16), and C4 (GOST-R), capable of operating in
high moisture and pollution levels at temperatures as low as -60°C
Specifications
- Power: Up to 25,000 kVA
- Voltage Class: Up to 36 kV
- Core: CRGO or amorphous
- Windings: Aluminum or copper
- Temperature Classes: F (155°C) or H (180°C)
- Cooling: AN or AF
- Protection: IP00 to IP56
- Ambient Temperature: -60°C to +60°C
Key Features
- Low energy content in the event of fire
- Self-extinguishing properties
- Excellent short-circuit resistance
