Abstract:
A dry-type power distribution transformer (10) has a generally rectangular, wound ferromagnetic metal core (20) and a resin encapsulated, generally rectangular coil (40). The core has a generally rectangular core window (22) within which is located a substantially straight section of the coil. When assembled to form a power distribution transformer, the shape of the coil's substantially straight section conforms to the shape of the core window. The transformer is inexpensive to manufacture, exhibits low resistivity and low core loss, and is lightweight, compact and reliable in operation.
