70. Free Download 110kV Underground Substation Layout CAD Drawing
This drawing set presents the layout solution for a 110kV underground substation designed in accordance with high-voltage electrical standards and integrated efficiently within an urban context. The overall floor plan clearly organizes the GIS room, control room, underground cable system, and technical pits. Reinforced concrete structural details are fully specified, including elevations, dimensions, concrete cover, and waterproofing solutions. Ventilation, drainage, and grounding systems are coordinated to ensure long-term operational safety and reliability. The documentation is suitable for design reference as well as practical construction implementation.
I also recommend downloading other Industrial plants and Factories CAD drawings for your project reference.
