A transformer coil is produced by forming a sheet of composite material over a plurality of annular shaped support plates to form an inner layer. A coil is wound around the inner layer. An outer layer is formed by wrapping a sheet of composite material over the coil. The outer layer is mechanically attached to the coil. A base is attached to the coil assembly and epoxy is used to encapsulate the coil. The epoxy forms a bond with the inner and outer layers, which become an integral part of the transformer coil.
