The Evolution of Substation Security Walls
In the early days, substations were primarily located on the outskirts of populated. These substations were secured by chain link fences. However, with the advancement and expansion, these substations grew in number as well found themselves in populated areas. Surrounded by communities, industrial and commercial development, these substations needed effective security, something more than just chain link fences.
To meet these demands, substation infrastructure was often colored with plastic slats. These slates were inserted in chain link fences that blocked the view. However, as the price of copper increased, these fences became the target of thieves that would cut and steal the fence links.
Keeping all the factors into consideration, the need for the hour was to have secure perimeter protection as opposed to chain link fences. This resulted in the adoption of solid parameters including blocks of precast concrete were considered as a viable option.
There were multiple reasons for the use of precast concrete security walls. The chain fence link walls were easily cut and infiltrated. On the other hand, they posed nominal security. Contrary, the precast concrete fences provided effective security measures.
The concrete walls provided fast installation, had better heights and could be decorated for different finishes. In addition, these also cost less than CMU walls and without continuous foundations, these walls were an affordable option. On the other hand, the greater the height the more it helped protect the substations from thefts and break-ins.
