Indoor switchgear ZRU-SESH 110 kV

General Description

Indoor substation ZRU-SESH 110/10 (6) kV is intended for use in dense urban areas. On the first floor of the substation building there are 10 (6) kV switchgears and auxiliary facilities (the room for charging batteries, the storage, the room with protection panels, etc.). On the second floor there is 110 kV circuit breakers. Transformers are located in separate rooms.

Attractive appearance.
Compact substation area.
Easy for maintenance.
The light weight of the structure comparing to the buildings made of reinforced concrete reduce the construction cost of foundation.
