This fully engineered system offers protection, switching, and communications in locations too constrained for traditional substations.
Southern States’ Substation in the Sky™ is a custom-designed solution for transmission line applications where space or infrastructure limitations make building a full substation impractical. Engineered to customer specifications, this system combines switching, monitoring, and communication capabilities to provide protection, sectionalizing, and isolation functions in a compact overhead structure.
Each Substation in the Sky™ solution is tailored to meet the voltage, current, and protection needs of the installation — often at a significantly lower cost than traditional ground-based alternatives. Whether used for remote taps, space-constrained corridors, or modular expansions, it delivers the flexibility and functionality of a substation… without requiring the real estate.
