High-voltage switching equipment manufacturer for electric utilities
Southern States manufactures mission-critical switching hardware for utility grids across North America—disconnect switches, capacitor and reactor switching gear, and protection equipment that transfer and balance bulk power. The tech stack reveals a manufacturing-heavy operation: ANSYS, COMSOL, SolidWorks, and AutoCAD dominate engineering, paired with Dynamics 365 and Business Central for operations and ERP. Active projects span multilevel converters for renewable energy grids, thermal management for high-power modules, and mechanical testing, indicating an engineering org modernizing for grid-scale decarbonization.
Southern States has manufactured high-voltage switching equipment for electric utilities since 1916, serving U.S. and Canadian power infrastructure. The product portfolio includes disconnect switches, capacitor and reactor switching gear, switch attachments, and current measurement systems—all engineered to transfer bulk power, manage system loads, and protect assets from overcurrent damage. The company operates from Hampton, Georgia, with a 201–500 person workforce split between engineering, manufacturing, operations, and support functions. Current project focus spans mechanical and dielectric testing, multilevel converter design for renewable energy integration, and thermal engineering for high-power modules, alongside process improvements in machine setup and material storage.
ANSYS, COMSOL, SolidWorks, and AutoCAD comprise the core design stack. Visual Basic and Java support custom engineering tools. Altium handles PCB design work.
Projects include multilevel converter development for renewable energy grids, high-power thermal management systems, mechanical and dielectric testing protocols, and prototype validation. Process initiatives target machine setup reduction and material storage efficiency.
