Description
The line includes models HMS-N36, HMS-A38, HMS-N24, HMS-N17.5/17.5C, HMS-A15, HMS-N12/12C, HMS-N7.2/7.2D and HMS-A5. The bays are built to IEC 62271-200 and ANSI/IEEE C37.20.2, so the switchgear is chosen to project norms. The general industrial version suits enterprise substations and distribution networks, and a separate version is for nuclear power plants. Air insulation simplifies inspection and maintenance without handling gas.
