BOLTED AND PINNED CONNECTIONS
A typical bolted connection for field assembly
requires a flat washer under the cap screw and one
under the nut. In instances where self-locking hex
nuts are specified, it is essential that the threads of
the associated cap screws be lubricated with a gen-
eral-purpose grease, to facilitate tightening. All pins
used in the field assembly should also be lubricated
to facilitate insertion.
Step 1
Cut the steel straps that bind the mounting pedestals to
the cross base, the straps that bind the container of mis-
cellaneous operating-mechanism components and hard-
ware, and the straps that bind the pole-units. Also remove
the wood bracing between the pole-unit terminal pads.
See Figure 2. For Circuit-Switchers rated 161 kV and
230 kV: Remove the lifting angles attached to the pole-unit
channel bases; retain these lifting angles and associated
hardware for re-use in Step 13.

CAUTION
Do not remove the containers from the interrupters,
or the plastic bubble-wrap from the insulating sup-
port columns, until the installation has been
completed.
