Before Starting
CAUTION
Do not remove the containers from the interrupters or
the plastic bubble-wrap from the insulating support
columns until the installation is complete .
NOTICE
Bolted and Pinned Connections: A typical bolted
connection requires a flat washer underneath the cap
screw and one under the nut . When self-locking hex
nuts are specified, it is essential that the threads of the
associated cap screw are lubricated with a general-
purpose grease to facilitate tightening . All pins and cotter
pins used in field assembly should also be lubricated to
facilitate insertion .
STEP 1.
Cut the steel straps that bind the mounting pedestals
to the high-speed base. Cut the straps binding the
container of operating mechanism components and
hardware and the straps binding the pole-units.
Remove any wood bracing between the terminal
pads. See Figure 2.
For circuit-switchers rated 161 kV and 230 kV:
Remove and discard the lifting angles attached to
the pole-unit bases.
CAUTION
The foundations and anchor bolts for S&C Mounting
Pedestals must be designed to meet the loading limits
specified in S&C Data Bulletin 716-61 .
Failure to meet
these loading limits can result in equipment damage.
