Southern States supplies a wide offering of Transmission Switching solutions in response to an increasing need for improved system reliability and reduced installation times. This range of solutions spans from a fairly basic group operated disconnect switch to building a customized “Substation in the Sky.”The ES-1, 1-way, 2-way, and 3-way phase-over-phase side break switches offer an easy to install solution for isolation and sectionalizing of loop and radial transmission lines. These configurations are often used in restricted right-of-ways where a substation is too expensive or transmission network sectionalizing is desired. Southern States also offers unitized designs for the vast majority of switch types. Unitized switches consist of all three phases, assembled and adjusted on a base, to speed up installation and simplify adjustments after mounting on the transmission line pole. Both the ES-1 and unitized switches are available with a full complement of accessories, operators, and interrupter attachments including the single gap,
LLS® Load Break Interrupter.
