A 1941 Westinghouse Electric Transformer Division of Sharon, Pennsylvania press photo. The woman in the photo is winding a coil of fine copper wire for a transformer of the type that is hung in residential districts. Since Westinghouse started making transformer cords of Hipersil, less copper wire is required in these transformers. The Company expects to save enough copper each year to make brass jackets for about 400 million 30-caliber army rifle shells.
