Stationary Spray Water Extinguishing System

Stationary Spray Water Extinguishing System with foam for 4 transformer á 267MVA incl. three phase earthing transformer

As the national grid company, Swissgrid has been responsible for the operation, safety and expansion of the 6700km extra-high-volltage grid since 2009. Swissgrid took over the grid in 2013, which represented an important milestone on the patz towards electricity market liberalisation.

The newly constructed transformer poles and the neutral point generator are optimally protected around the clock by the automatic deluge system with foram admixture. If the detection system (pneumatic and/or electrical) detects a hot spot, the extinguishing system is automatically triggered and the area to be protected is cooled with extinguishing water or extinguished by adding foam. Early detection and subsequent cooling can reduce further damage to the system and costly failures.
