Dry-Type Epoxy-Resin Distribution Transformer Operating Conditions
  • Ambient Temperature: Operating temperature range: -40℃ to +40℃; Maximum average temperature over 24 hours: ≤35℃; Maximum temperature in hottest month: ≤30℃ (average value over many years).
  • Relative Humidity: Maximum relative humidity ≤95% (ambient temperature at 25℃); No condensation or icing on the transformer surface.
  • Altitude: Installation altitude ≤1000m above sea level. For installations above 1000m, derating is required according to relevant international standards (IEC 60076) to ensure stable performance.
  • Installation Environment: Install in a well-ventilated, dust-free, non-corrosive gas, non-explosive and flammable environment; Avoid direct sunlight, heavy rain, and severe vibration (vibration acceleration ≤0.1g).
  • Cooling Condition: Natural air cooling (AN) under normal operating conditions; For high-load scenarios, forced air cooling (AF) can be equipped to improve load capacity by 30%-50%.
