Transformer fire bars, high voltage transformers, or transformer fireproofs, are essentially outdoor countermeasure against cascading electrical failures within a national power grid. These are essential because a power outage can shut down an entire state or country for several hours at a time. It can also lead to a deadly blackout which will, in turn, affect millions of people and businesses. In addition, a blackout can render commercial lighting and other emergency electrical systems inactive. The existence of both of these factors coupled with the threat of a devastating failure in the electric power grid makes the installation of these protective barriers absolutely essential.

Many electrical power plant (PEPC) generators and other electrical generation facilities utilize substations that are situated hundreds of miles from the main power grid. Due to the length of electrical lines and the associated difficulties in foundation erection, these substations are often prone to temporary failures that can overload the electrical system. In many cases, this overload is not necessarily a one time occurrence but rather a constant threat that only grow worse over time. In order to prevent the catastrophic event known as blackouts, which can cause everything from interruptions of daily life to serious safety risks for the population itself, the immediate installation of transformer fire barriers is necessary.
The multitude of benefits provided by the use of these barrier systems are beyond what is presented here. However, the simple fact of the matter is that these barriers to provide the necessary back up to emergency generators and other emergency power systems in case of a devastating emergency such as a natural disaster or a fire outbreak. While it may not be possible to completely eliminate the threat posed by a failing electricity system, the addition of transformer fire barriers will help protect the lives and properties of those who reside in proximity to the closest units.
