Substation structures are mainly divided into two categories:
Steel structure structures: These use a combination of steel beams and columns, offering high strength and seismic resistance. They are suitable for 500kV and above ultra-high voltage applications and can support complex wiring systems. A typical characteristic is the high column height and slender cross-section, making them highly flexible structures.
Reinforced concrete structures: These achieve a balance between economy and durability through composite materials, making them more adaptable to corrosive environments or landscape-sensitive areas.
Based on equipment arrangement, they can be divided into:
Portal frame structures: Suitable for single-layer equipment arrangements, with the main support rods and inclined support rods forming a triangular stability structure.
π-type frames: Adaptable to multi-layer equipment arrangements, achieving three-dimensional support through crossbeams and multiple support rods.
