Compact Design: Integrates multiple substation components into one small unit, saving significant space.
Factory-Built: Pre-assembled, tested, and ready for quick installation, reducing construction time and costs.
Integrated Components: Includes a step-down transformer, HV switchgear (VCB/RMU), LV distribution panel, and protection devices.
Versatile Application: Used for stepping down high voltage to lower voltages in commercial buildings, mines, construction sites, and urban areas.
Ready-to-Use: Mounted on skids or wheels for easy transport, often weatherproof for outdoor use.
