Outer switchgear package (OSGP)

The need of a proper electric power distribution to the end-user and to the power plant's own needs is an important aspect in the facility's undisturbed operation. The innovative OSGP-6 (10) cells designed to receive and distribute 50 Hz 6 and 10 kV electric power of three-phase AC are manufactured at the production site of the MKS Group of Companies. OSGP-6 (10) are used in distribution devices of the power plants' auxiliary needs, electric substations of power systems and industrial enterprises, as well as in power supply facilities of the agriculture sector essential consumers.

Design configuration

The OSGP cells are a welded metal structure of bent steel sections, the cells frame can be as well made of galvanized steel using rivet joint technology.
