SLENDAUR High Voltage Starters
3.3kV and 6.6kV Fuse Protected Vacuum Contactor Unit
The
SLENDAUR range of fuse protected vacuum contactor units is of the
single tier withdrawable pattern, suitable for connection to
breakers or isolators for the complete switchboard format.
The fixed housing incorporates phase segregated busbars,
fast make earth switch and individual HV and LV Outgoing cable
chambers.The truck withdraws on nylon wheels and incorporates fully
segregated LV and HV components, to allow safe and unrestricted
access for testing and maintenance purposes.
A comprehensive
system of mechanical interlocks in provided between truck, isolator,
contactor, earth switch and LV compartment door.
