Fire Protection for Power Distribution

HI-FOG® for Power Distribution

Electrical substations are the key nodes of the electrical grid. Some have an open structure and are visible for anyone, but many critical facilities are hid from the public eye underground or landscaped to fit in the city architecture. Power transformers pose the biggest individual fire risk in substations having thousands of liters of oil for cooling and insulation. 

HI-FOG® water mist fire protection offers superior performance to cool down and suppress high heat release rate flammable liquid fires such as transformer fires. Water mist is a safe technology for the people and the environment.

HI-FOG® solutions are available from a single transformer protection to full substation protection covering also cable spaces, electrical spaces, switchgear rooms, battery energy storage systems and administrative areas.
