摘要： A winding arrangement for a transformer includes a plurality of stabilising elements, a winding block, a top end press element and a bottom end press element. The top end press element is arranged on a top end of the winding block and the bottom end press element is arranged on a bottom end of the winding block. The plurality of stabilising elements are arranged to make the winding arrangement self-supporting and isolated from short circuit forces, wherein the at least one stabilising element comprises any one out of: at least one insulated tie-rod made of fibre glass or plastic, arranged between the top end press element and the bottom end press element and at least one insulated band arranged around the winding block, the top end press element and the bottom end press element.
