* - In the valveside winding, switching from the У scheme to the Д scheme is provided.
For transformers of the ТСП and ТСЗП type, by agreement of the parties, 380/230 V voltage versions are possible. Transformers in tropical design (04) are available with rated voltage of the mains winding - 380, 400, 415, 440 V. Insulation heat resistance class for temperate climate "F", for tropical - "H" according to GOST 8865-87.
