* - The primary winding of the transformers has a regulation of ± 5%. The
transformer windings can be connected according to the scheme YY0 or DY11.
Transformers of the ТСЗП-10/1В-04 type in tropical execution are available with a nominal voltage of the secondary winding
380, 440 V.
Insulation heat resistance class for temperate climate – "F", for tropical – "H" according to GOST 8865-87.
