VES-S 15-69kV Line Sectionalizer Switches and Systems

Ideally suited for line sectionalizing on 15kV to 69kV systems.

Vesco VES-S® Sectionalizer Switches and Systems

  • System ranges from 15kV–69kV, providing excellent solutions for substation or pole mounted installations
  • Complete system installations are available with the sectionalizer switch, control, cable, and pole/pedestal mounting frame
  • Vacuum interruption and solid dielectric insulation provide a completely oil and gas free design
  • Delivering up to 15,000 maintenance-free operations
  • Quickly isolates faulted sections of an electrical distribution circuit from the rest of the system
  • Compact, lightweight design makes them easy to handle and may be conveniently mounted on poles or simple structures.
  • No coordination is needed between sectionalizers, allowing any number to be used in series to provide maximum circuit reliability
  • Replacement parts are readily available for existing installations including full mechanisms, controls, interrupter modules, cables, and others.

Vesco VES-S® sectionalizers are designed to improve the continuity of service of power distribution systems by isolating faults which confines outages to a small number of customers.  These sectionalizers combine Vesco’s long-life vacuum switch with electronic controls.  Incorporating the electronic controls into the provide automatic sectionalizing and/or remote-supervisory operation.  

VES-S switches are manufactured for system voltages ranging from 15kV to 69kV.  As a protective device that automatically isolates a faulted section of line from the rest of the distribution system, the Vesco VES-S counts the number of operations of an upstream interrupting device that feeds the circuit, such as a recloser or relay-controlled breaker back at the substation.  After a pre-selected number of current interrupting operations have been “seen”, the VES-S sectionalizer opens and the feeder or line on the load side of the sectionalizer is not re-energized.

The Vesco VES-S Sectionalizer simplifies the job of restoring service after a fault has been removed.  Each switch ships completely factory-assembled, tested, and ready for fast and easy field installation.  With their compact and lightweight design, the VES-S design does not require special foundations or support for installation.  Both pole and ground mount frames are available as an added option.

Additionally, Vesco offers sectionalizer controls with a wide range of AC and DC voltage control package options that pair with our switches.  All electrical control connections to the operating mechanism are made through a single environmental-control cable connector, which are available in multiple configurations and lengths.
