ES-1 Transmission Line Switch

Learn More

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.

MACI® Patented Product

Southern States’ MACI™ helps verify proper blade depth and rotation of high voltage disconnect switch closures. By adding MACI™ to your new or existing switch applications, you will ultimately reduce the risk for switch failures, power outages, and the high costs associated with such.

Ballisti-Wall® Installation

Learn More

Southern States recently launched custom designed ballistic resistant solutions for utilities’ critical facilities and equipment: Ballisti-Wall® and Ballisti-Cover®.

These ballistic barriers prevent damage to critical assets through a surrounding resistant wall panel enclosure that is designed to protect against projectiles. These solutions are constructed by using layer upon layer of woven fiberglass that is encapsulated with a proprietary resin system. This system produces a hard ballistic resistant panel that retains hazardous ricochet.

Original developed for use by the Department of Defense, ballistic protection solutions are military grade protection for critical asset facilities. Ballistic resistant security offers performance advantages such as durability, corrosion resistance, electrical non-conductivity, low thermal conductivity, lightweight, and movable features for easy repairs and installations.

Ballistic resistant solutions are designed for maximum security. With quick and easy installations and integrations surrounding any type of critical facility.

Both the EV-1 Vertical Break Switch and RLSwitcher® (Reactor Switcher) at 500kV meet IEEE 693 High Performance Level Seismic Test criteria.

Safety Enhanced Gear Operator

Learn More

The Safety Enhanced Gear Operator, or SEGO™, providing a dynamic self-locking action with backwards holding torque of 12,000 lb-in (a torque of 12,000 lb-in can be applied to the output shaft and it will not drive the input shaft) preventing back driving of the handle in situations like these, eliminating the safety danger to operating personnel.
