300KVA NEMA 3R Three Phase Dry Type Transformer 480Y/277V 220Y/127V
1. Feature
■ Energy saving and low noise
The use of high-quality cold-rolled silicon steel sheet stacking.The use of a special dipping process to effectively reduce the vibration and noise during operation,and the introduction of new processes and new technologies such as the design of high-temperature-resistant insulating materials, making the transformer more energy-saving and quieter . The energy-saving and low-noise coil has a ventilation slot, and the air flows smoothly, effectively reducing the temperature of the coil.
