Unitized Center Break Switches
Quick Install Switches
“Quick Install” CB-AV switches, adjusted and prepared for shipping
Cleaveland/Price “Quick Install” center break switches are unitized, phase-over-phase transmission switches that ship from the factory fully assembled and adjusted. Unitized assemblies are available through 161 kV. The switch pole units are “V” configuration CB-CV and CB-AV designs to minimize weight.
“Quick Install” switches are designed to address issues that customers have with other transmission switch designs. Some customers have difficulty getting switches into adjustment when mounted on tall transmission poles. This is the result of the torsional “windup” of the vertical operating pipe between phases, which causes the three pole units to operate out of sync. “Quick Install” switches are designed with “push-pull” interphase linkage so that the three pole units always move in unison, regardless of the length of the vertical operating pipe.

The switch ships from the factory fully adjusted with the linkage set in toggle in the closed and open positions. The switch stays in adjustment after installation, just as it was tested and operated at the factory.
The switches are typically supplied with standard strength porcelain insulators. Polymer insulators are available on 69 kV and 115 kV switches with a maximum short time peak rating of 65 kA. Center break switches can be supplied with arc horns, Cleaveland/Price Superwhip®, or single bottle ReliaVac® vacuum interrupters for loop splitting application.
