Application
The Farady overhead 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. Our single phase overhead distribution transformer is
commonly used in various places including rural areas, remote regions and scattered villages to provide high
quality power supply for daily lighting, agricultural production and industrial plants. Aside from these, it is also
suitable for the energy saving projects for railway and urban grid.
