Product Detail
1. Product Display
Although some are used for stepping down to commercial and industrial voltages such as 277, 240/480, 2400 and 4800,most are used for stepping down to the single-phase voltage of 120/240.
These same transformers are also used for small substations,miscellaneous applications and can serve to step up voltages.

Product 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.
