What are the surge levels?  You can get high voltage relays from
common electronics suppliers, such as Digikey - they have up to 10kV
reed relays, such as DAT70510 or H24-1A69.  You'll have to go to power
company suppliers if you want to switch higher voltages.

Alternately, it's not hard to make a high voltage, low current
contactor yourself with a servo or solenoid.  Remove the tab from the
RJ45 connector, and let the solenoid or servo attach and detach the
cable.  A little bit of mechanical work is good for the engineering
mind anyway.
