GEMIS® 24/20

Air - insulated medium - voltage switchgear for Energy supplier





GEMIS 24/20®, an air – insulated, medium voltage switchgear, can be installed in most fields of industry, in building technology and in the domain of power supply.

System design and development is based on IEC 62271-200 and meets the high demands respecting operator safety, operational availability and ease of use.

A key benefit of the newly developed 24 kV – switchgear is the lower space requirement due to small dimensions.

The special engineering and design does compromise the flexibility in no way.

Upon request the switchgear can be equipped with load – break switches with or without fuses, optionally with earthing switch.

Tested resistance to accidental arcs according to IEC 62271-200 ensures pressure relief upward and / or downward.
