Medium Voltage load break switch-disconnectors 12-24 kV

Main CharacteristicsAdvantagesUsesGRANY switches/disconnectors are used for the production of very compact medium voltage cut-off devices in insulating gas. They consist of a moulded enclosure of epoxy resin, permanently sealed and filled with sf 6. Movable contacts are triggered by manoeuvred mechanisms or mechanical energy reserves for a control manoeuvre. These switches are motorised and can design a wide variety of MV device functions in order to meet various needs in your applications. 1. Nominal voltage: 5.5 kV to 24 kV 2. Dielectric resistance voltage: 50 kV (insulation)/60 kV (disconnection) 3. Shock resistance voltage: 125 kV (insulation)/145 kV (disconnection) 4. Nominal heat current: 630 A 5. Nominal breaking capacity: 12.5/16/20 kA 6. Nominal admissible short-term current: 12.5/16/20 kA 7. Closing power: 31.5/40/50 kA 8. Operating temperature: - 25°C + 50 °CGet price
