A method of forming a transformer coil, wherein first and second fibrous layers are provided. Each of the first and second fibrous layers includes a fabric formed from a plurality of interconnected fibers and a plurality of spacers affixed to the fabric and protruding therefrom. A conductor layer is disposed over the first fibrous layer such that a first side of the conductor layer contacts the spacers of the first fibrous layer. The second fibrous layer is disposed over the conductor layer such that a second side of the conductor layer contacts the spacers of the second fibrous layer. A resin is applied so as to cover the conductor layer and the first and second fibrous layers.
