Unitized Vertical Break Switches
Quick Install Switches
Cleaveland/Price “Quick Install” vertical break switches are unitized, phase-over-phase transmission switches that ship from the factory fully assembled and adjusted. Unitized assemblies are available through 230 kV. The switch pole units are V2-CAS design with an inclined jaw end insulator to shorten the base and reduce switch 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 utilize a “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. At voltages to 115 kV, vertical break switches can be supplied with polymer insulators. Vertical break “Quick Install” switches can be supplied with arc horns, Cleaveland/Price Superwhip™, or Cleaveland/Price ReliaVac™ interrupter, depending on current interrupting requirements.
