ILO-C In-line Transmission Switch

ILO-C Overview

The ILO-C is a versatile in-line disconnect switch that is useful in a variety of applications.  The switch was originally designed as an in-line disconnect switch to sectionalize long transmission lines.  The ILO-C design saves significant installation costs.  The switch mounts in line with the transmission line conductor eliminating the need for a group operated switch with associated mounting structure. The ILO-C is available with the ultra-fast SuperwhipTM quick break whip to interrupt the line charging current of long sections of transmission line.

As customers became aware of the switch, they recognized its use in additional applications such as:

  • Substation isolation
  • In-substation sectionalizing
  • Line tap
  • Maintenance applications to replace jumpers
