Indoor switchgear ZRU-SESH 35/10(6) kV

General Description

Indoor switchgear ZRU-SESH 35/10 (6) kV, is used by electrical utilities & generation . On 35 kV side there are KRU-SESH-65 cubicles in modular building, on 10 (6) kV side there are KRU-SESH-70 cubicles in a modular building. In the center of ZRU-SESH 35/10 (6) power transformers are installed in the module.

Attractive appeareance.
The equipment is installed indoors, which eliminates the impact on the equipment of the external environment and allows the maintenance of equipment inside the building.
KRU-SESH-65 has withdrawable part, which allows easy maintenance. Possible to be manufactured as a whole if necessary.
The possibility of transporting blocks by any type of transport, both railway and road.
Substation is supplied with ready-made units, which eases and shortens the time of installation of the substation.
