[for breaking a 9.525 mm 3/8 inch coating of ice before contacts are opened
or closed].] Each switch shall be rated for [14.4] [25] [34.5] kV, [110]
[150] [200] kV BIL, with a continuous current rating and load-break rating
of 600 amperes, and a momentary rating of 40,000 rms amperes asymmetrical.

GROUP-OPERATED LOAD INTERRUPTER SWITCHES
2.19.1
Manually Operated Type (Switch Handle Operated)
Manually operated (switch handle operated) load interrupter switches shall
comply with NEMA C37.32 and shall be of the outdoor, manually-operated,
three-pole, single-throw type with either tilting or rotating insulators.
Switches shall be equipped with interrupters capable of interrupting
currents equal to the switch's continuous current rating. Each switch
shall be preassembled for the indicated configuration and mounting. Moving
contacts shall be of the high-pressure, limited-area type, designed to
ensure continuous surface contact. Switches shall be fused or non-fused as
indicated. Switches shall be complete with necessary operating mechanisms,
handles, and other items required for manual operation from the ground.
Switch operating handles shall be located approximately 1.1 meters 3 feet 6
inches above final grade. Insulation of switch operating mechanisms shall
include both insulated interphase rod sections and insulated vertical
shafts. Each handle shall be provided with a padlock arranged to lock the
switch in both the open and the closed position.
[2.19.2
Remotely Operated Type (Stored-Energy Actuator)
**************************************************************************
NOTE: SF6 switches are available for nominal
voltages of 15 kV through 34.5 kV in 600 ampere
continuous and load-break ratings. Delete SCADA
equipment and remote telemetry when not required.
**************************************************************************
Remotely-operated, [air-insulated] [SF6 insulated] load interrupter
switches shall be rated in accordance with and comply with the requirements
of NEMA C37.32 and shall be of the outdoor, three-pole, [pole-mounted]
[crossarm-mounted] type. Interrupter devices shall be [air-insulated]
[SF6-insulated, puffer-type] switches capable of interrupting currents
equal to the switch continuous current ratings indicated. Switches shall
utilize an electric motor-charged, stored-energy (spring-driven) operator
to simultaneously trip all phases. A switch-control unit shall be provided
[for push-button operation from the ground] [for push-button operation from
the ground and remote switch actuation via telemetry]. The switch-control
unit shall be pad-lockable, tamper-resistant, in a NEMA ICS 6, Type [3R]
[4] [4X] [4X-SS] enclosure, which is connected to the switch actuator by a
shielded control cable. Control power for closing and tripping shall be
provided by a battery mounted in the control unit enclosure. The switch
control unit shall be provided with a separate 120 volt ac circuit for the
battery powered. Power for charging the operator mechanism may be 120 volt
