Installation
Installing the Wildlife Disks:
Before installing the wildlife disks, determine
the proper placement of the disks on the switch
blade and contact insulators.
On 14.4-kV Omni-Rupter Switches
(Porcelain and Cypoxy® Insulators)
Install the wildlife disk to the bottom skirt root
of the insulator on both the blade and contact
ends of the switch. When the wildlife disks are
properly installed, the disks will overlap slightly
as shown in Figure 13.
On 25-kV Omni-Rupter Switches
(Porcelain and Cypoxy® Insulators)
Blade-end of the switch: Install the wildlife disk
on the bottom skirt root of the insulator.
Contact-end of the switch: Count up two
skirts from the base and install the wildlife disk
to the insulator on the blade-end. When the wild-
life disks are installed properly, they will be at
approximately the same height. See Figure 14.
