Note:

Rectifying unit consists of two cases of controlled rectifiers and control unit case.

All cases of rectifying unit have one way service.

Control unit case is set on the one of the cases of controlled rectifiers.

Rectifying unit RITG-5400/810-U2 have overall dimensions, that are 1,5 times less of the similar rectifying unit M-TPP-3000-U2, produced by OJSC «Electrovipryamitel», Saransk for PJSC “Kolomensky Zavod”.

Performance test of the controlled rectifier assembled with the control unit case of the rectifying unit for traction generator type VUTG-5400/810-U2 at “Electrtotyazhmash” Plant.
