Yes. A set of three single-phase transformers used in this way is called a 'three-phase transformer bank'. Three-phase transformer banks are more common in North America than in Europe, where three-phase transformers tend to be the standard.

The type of transformer is dictated by the type of supply. A three-phase supply is used in power distribution because it dispenses with half the wire and therefore half the power losses in the circuit.
