Is crushed stone or washed natural gravel preferred in an electrical Substation?

In an electrical substation, crushed stone is typically preferred over washed natural gravel for several reasons. Crushed stone provides better drainage and stability, helping to prevent erosion and ensuring that the ground remains level and well-drained. Additionally, its angular shape allows for better interlocking and compaction, which is important for supporting heavy equipment and electrical infrastructure. Overall, crushed stone enhances safety and reliability in substation operations.
