Structural Features
This transformer may be used alone for the supply of a single phase
load or as one of three units in a bank for the supply of a three
phase load. The unit may be direct-mounted to a wooden or concrete
pole, or cluster mounted on a pole for three phase use.The single
phase oil-immersed transformers are designed for servicing
residential overhead distribution loads. They are also suitable for
light commercial loads, industrial lighting and diversified power
applications.
