FIELD: electric engineering.
SUBSTANCE: invention is related to repair of electric machines, when it is required to remove external layers of insulation by means of depolymerisation. Depolymerisation of thermosetting binding agent of electric machines insulation is carried out by means of insulation treatment in alkaline solution, in which dimethyl sulfoxide is introduced, with the following ratio of components, in weight parts: technical caustic soda - 10, dimethyl sulfoxide - 5, technical water - 85.
EFFECT: reduction of duration and labour intensity of technological process, increase of quality level of repaired electric machines with reduction of repair expenses.
