The hinge assembly on each phase shall consist of a sealed threaded
current transfer path and a counterbalance spring to allow the
disconnect blades to be under full positive control during opening and
closing operations.
3.07.04 Switch Blades
(Supplied on vertical break disconnect switch model circuit switchers)
The switch blades shall be tubular aluminum with a removable tin plated
copper contact plate having 15 mils brazed silver inserts. The blade
contact plate and the contact fingers shall be supplied with silvers of
differing hardness so that galling does not occur. The switch blades
shall have a rotating motion upon opening to release contact pressure
and upon closing to engage contact pressure, to wipe the stationary jaw
contacts clean of any contaminants, and to break any accumulated ice
build-up. The interrupter shall open before the disconnect switch blade
opens and shall close after the disconnect switch blade closes, thus
making and breaking the circuit in an SF

environment. Circuit switchers
that make the circuit on the switch blades are not acceptable.
