ILO-CB In-Line Substation Switch

ILO-CB Overview

The ILO-CB is a hookstick operated switch that can be used to isolate or sectionalize bus sections within a substation. With the ILO-CB, space and money can be saved within the substation by not having to install footings and a structure for a gang operated switch. Installation involves cutting into the tubular bus run and clamping the switch to the bus ends or bolting the switch to a bus connector. On switches rated 69 kV and higher, the switch blade engages a latch when the switch is fully open, keeping the blade parallel to the ground. The ILO-CB is available in voltage ratings from 15 kV through 138 kV.
