Dry-type transformers
35 kV Low-Noise Dry-Type Power Transformer
Down to 45 dB — quiet enough for hotels, hospitals and city centres.
- 50–20,000 kVA
- 20–35 kV
- ≤45 dB
Cast-resin dry-type transformers for 20 kV and 35 kV systems with ultra-low noise design: resonance frequency, noise wavelength and natural frequency are engineered at the source to bring operating noise down to 45 dB(A).
