Low sound transformers are designed to have average sound levels 3 dB below NEMA ST-20 standards. Depending on KVA rating and KV class, we may be able to reduce sound level up to 7 dB below NEMA.

Note:Sound levels are measured in a sound room, not at the installation. These quieter transformers are ideal for noise sensitive installations such as schools, hospitals, libraries, and offices. Proper installation procedures should be used to achieve maximum benefit.

Available in single-phase ratings 15 - 500 kVA and up to 15000 volts primary
Available in three-phase ratings 15 - 3000 kVA and up to 15000 volts primary
