SW series
Characteristics
The SW off-load switch is a complete range designed to cover all the applications to be met in DC traction power substations and other industrial applications. Its modular concept enables to build single pole or double poles SWS disconnect switches, SWI change-over switches or SWG disconnect and earthing switches, for insulation voltages 3000 Vac/dc or 4800 Vac/dc and rated thermal current from 2000 to 8000 A. Installed inside cubicles, the SW switch can be operated either manually or electrically, and the customer can select among standard options, safety interlockings made via key locks, and/or electro-magnets. The severe testing procedures applied for the type testing as well as for the serial testing make the SW switch a safe component with a unique design and a high level of reliability.
