CB-AV “V” Aluminum Center Break

The “V” configuration of the CB-AV makes the switch ideal for low profile substation installations. 

The switch can also be installed on a pole in phase-over-phase or phase-opposite arrangements for transmission line applications.  For transmission line applications at 115 kV through 161 kV, the switch can be supplied with high line charging current interrupting SuperwhipsTM.

CB-AV Performance Features

  • High-pressure line contacts
  • Magnetically attracting parallel path hinge and jaw contacts increase contact pressure under short circuit
  • Non-breakable, tin-plated hard-drawn copper terminal pads with NEMA Standard hole pattern
  • Silver-to-silver contacts
  • Stainless steel contact springs and live parts hardware

CB-A Aluminum Center Break

The Cleaveland/Price CB-A is a three pole, group operated, aluminum center break switch used primarily in substation applications. The switch is available in rating from 69 kV through 345 kV.

The center break design is useful in applications where a customer wishes to use a more economical switch that utilizes two insulators per pole instead of three per pole as in a vertical break or double break switch. The switch can be used in applications where there is limited overhead clearance.

CB-A Performance Features

  • Aluminum blades and tin-plated copper current carrying parts
  • High-pressure, silver-to-silver contacts at hinge and jaws
  • Non-cast, tin-plated copper terminal pads with NEMA standard hole pattern on three planes
  • Blade guide with generous lead-in
  • Blade alignment provision
  • Stainless steel contact springs
  • Arc horns / Ice shields
  • Rigid hot-dip galvanized base assembly
  • Rotating insulator stops
  • Insulator jacking bolts on double channel bases

Group Operated Switch Overview

138 kV CB-A InstallationCleaveland/Price offers many group operated switch types including vertical break, center break, double end break and single end break.  All of the switches are available with copper current carrying parts.  The switches are typically supplied as three pole switches for substation, transmission, and distribution applications. The switches can be mounted in the horizontal-upright, vertical, horizontal-underhung, or inclined position.

The switches are suitable for use in a variety of applications including line disconnecting and sectionalizing, circuit breaker by-pass and isolation, and transformer isolation.  Arc horns or quick break whips are available when small amounts of transformer magnetizing currents and line charging currents must be interrupted.

Full load break attachments are available for vertical break switches. Accessories needed to adapt the switch to a customer’s particular requirements are available.

The switch may be manually operated by use of a swing handle or wormgear mechanism or electrically operated by use of a Cleaveland/Price TP-C2 motor operator.

Cleaveland/Price’s switches meet ANSI C37, NEMA, and IEEE Standards and the rating requirements of IEC Standards.
