Through Southern States’ research and development, understanding of existing issues, and integration of user feedback, the ES-1 family was designed to provide a reliable, quality product that resolves many of the common issues experienced by one-way and multi-way transmission disconnects.
The unique blade design with jaw end pivot produces a very low operating effort, eliminating concerns of operator dependent force requirements on closing. By shipping the phases assembled on a platform, the switch is easy to install and requires minimal adjustment.
The design is also compatible with the only single gap, Load Break Interrupter (LLS®) available through 145 kV.
