Although copper has very low thermal resistance, electrical in-sulation and voids raises the R T within the winding. This is a design area where expertise and experience is very helpful.
The physical dimensions (volume) of a transformer can be varied for any given design. The core of the toroidal transformer is made of a strip of grain oriented silicon steel. The strip width determines the height of the core while the inside and outside diameters determine the physical dimensions and the cores cross-section area.
