PRODUCTION DETAILS

Underground Combined Power Transformer Substation OEM ODMUnderground Combined Power Transformer Substation OEM ODM

Use environment
1. Altitude: ≤1000 meters.
2. Temperature: High temperature: +40ºC; Low temperature: -45ºC; High monthly average temperature: +30ºC; High annual average temperature: +20ºC.
3. Environment: No explosive, corrosive liquids, gases, or dust. Installation sites should be free from severe vibrations and allow complete submersion in water for a certain period.
4. Ground acceleration induced by earthquakes (Ag): Horizontal direction <3m/s; Vertical direction <1.5m/s.
5. Power supply voltage waveform: Approximately sine wave.
6. Three-phase power supply symmetry: For three-phase underground transformers, the three-phase power supply voltage should be approximately symmetrical.
