Therefore. @The frame is, for example, the first cylindrical part around which the inner winding, which is the primary winding, is wound. It consists of a cylindrical part with a larger cross section extending coaxially at both ends. This end cylindrical part supports the insulating paper that wraps the primary winding. A secondary winding is wound around it.
