The Evolution of Substation Security Walls
In old times, substations were constructed away from the residential areas and protected with chain-link fences. By the time, due to the rapid increase in population, these substations found themselves surrounded by residential areas. it was due to an increase in the population, commercial and industrial development.


Well, substations are national assets and need to be protected. Therefore, when residential and industrial units came adjacent to substations they were protected by using colored plastic planks in chain link fences.
Unfortunately, it was a very fragile and vulnerable solution. So, substation located in populated areas started using masonry transitions. Meanwhile, copper became very expensive. So it became difficult to use a huge amount of copper to build fences. Moreover, the theft risk for copper was also increased tremendously.
Then concrete utility walls came into play as the most suitable option to prevent vandalism and theft. So, the substations where generally chain link fences were used got replaced with solid precast concrete fences to achieve maximum security and protection against line of the sight, break-ins, and thieves. Also, concrete walls are the best option to count in to build tall security walls due to their fast installation and ease of construction.
