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. As with the transmission class ILO-C, the switch blade engages a latch when the switch is fully open, keeping the blade perpendicular to the ground. The ILO-CB is available in voltage ratings from 69 kV through 161 kV.
69-138 kV, 1200 A.
