Abstract
An assembly includes at least one winding and a housing in which the winding is disposed. The winding has at least one electrical conductor and a cellulosic or cellulose-containing insulation material at least partially surrounds the winding and/or the electrical conductor thereof. The housing is filled with a liquid coolant during operation so that the winding is located in a liquid coolant during operation. In addition to existing cellulose-containing insulation material which encloses the winding and/or the electrical conductor thereof for insulation purposes, the housing and/or a coolant circuit for the coolant contains at least one composition containing chemical compounds for reducing the aging of cellulose-containing insulation material. A method of reducing the aging of cellulosic insulation material of a winding is also provided.
