RU-825PP switchgear (switching with disconnector)
Switchgear RU-825PP is designed for operation in metro depot traction network as contact rails feeding circuits switching device.
Switchgear RU-825PP is structurally made in form of metal two-sectional double-side serviced cabinet. One disconnector type EDT 4000 with visible double break is installed in the right section. Busbar for cables connection is in the left section. The cabinet has doors locked with the help of a key.
