JERVIT (MV) SWITCHGEAR

Jervit GD85 10kV Switchgear

Jervit GD85 10kV Switchgear system can be used for a wide range of power distribution and motor control applications at rated voltages up to 24 kV. The system is available in single and double busbar (duplex) configurations. The Loumiere H70 withdrawable primary switchgear has been designed with safety in mind and offers a reliable and flexible solution with a compact footprint. The compact design of Jervit GD85 Switchgear relies on two main technologies i.e cast-resin insulation and vacuum interrupters.
