4. Silent Operation
Noise levels stay below 65dB—perfect for hospitals, schools, or residential areas.
4.Where It Performs Best？
Industrial Facilities
- Withstands 150% overloads for 2 hours in mining/oil & gas operations.
- Seismic-resistant designs meet Zone 4 earthquake requirements.
Solar/Wind Farms
- Handles 125% intermittent loads from inverters.
- Low-loss (<3% at 30% load) models maximize ROI.
Utility Grids
- Amorphous core options achieve 99% efficiency for EcoDirective compliance.
- Modular designs simplify grid expansion.
5.How It Works: Simplified
The 10kV Oil-immersed Distribution Transformer uses a magnetic core to step down voltage. Insulating oil cools the windings while preventing arcing. Advanced tap changers adjust output voltage dynamically, maintaining stability during demand spikes.
6.Quality That Meets Global Standards
Our manufacturing process includes:
- Material Testing: Grain-oriented steel cores reduce hysteresis losses.
- Leak Checks: 24-hour pressure tests on welded tanks.
