MEDIUM VOLTAGE SWITCHGEAR SYSTEM NES-D
Draw-out type switchgear system for indoor installation, type-tested, factory-assembled, air-insulated, metal-enclosed with an eightfold compartment, double busbar system.
Optional: motor operated withdrawable units, circuit breaker/disconnector and earthing switches.
For the conduction of hot gases that result from arc faults, the switchgear system is equipped with internal pressure release ducts. Optional: conduction out of the control room or a release in the control room with an accumulative absorber.
