112.5Kva Three Phase Pole Mounted Overhead Distribution Transformer
Oil Immersed 13.8KV 15 kva 25KVA 50kva 75kva 20KV 13200V 7620V to
240V
WINLEY’s Three Phase Pole Mounted Round Tank is designed for
service in areas where three phase power is needed, but space is
limited. It provides a cleaner looking service with lower
installation cost than a bank of three single phase transformers.
Triplex core/coil is the choice for serving electric motor loads
especially with frequent motor starts.
Standard Features
