Elektronvest Switchgear’s world renowned GVR Recloser was the first in a range of equipment utilizing one of the most advanced operating mechanisms available on the market, featuring the award-winning magnetic actuator technology.
Key Features
Superior, proven technology with minimal maintenance
BRUSH Switchgear’s, single coil magnetic actuator mechanism allows the GVR to operate independently of the MV supply
Environmentally friendly vacuum interruption produces no by-products
The lightweight corrosion resistant aluminium tank makes the GVR easier to transport and install
The EPDM or silicone bushings are tested for tracking and erosion to IEC 61109 and are resistant to damage from vandalism or mishandling
Endurance tested to 10,000 operations
Pole mounted or substation mounted, the GVR can be integrated into the most advanced distribution automation schemes, or can operate as a stand-alone recloser
By using the advanced control and protection functions of the Beckwith M-7679, the GVR can also be used in applications where reclosers have not traditionally been used such as closed rings and underfrequency load shedding schemes
The 3-in-1 Recloser – the GVR can be configured to function as a Switch, Sectionaliser or Recloser by using one of the specially pre-engineered protection and control cubicles
