Fire-retarding covering Type BN-OF

Fire-retarding covering Type BN-OF

The fire-retarding covering BN-OF was developed as an alternative to the conventional coverings. The basis is the well-known perforated metal plank type BN-O, which Lichtgitter is producing and distributing for quite some years. The advanced type BN-OF is especially suitable as a covering for the oil collecting pans beneath the transformer units. In case of fire the flames are restrained by the limited air permeability, but not stifled.


Characteristics

  • Better and quicker control of the collecting pan
  • Shorter switch-off period of the transformer
  • Optimum flow time speed of oil, tempering and rain water
  • Quick possibility to remove the liquid out of the collection pan
  • In case of fire in the collecting pan this system can contain and delay
  • Serial production – short delivery times
  • High safety level during maintenance operations
  • Existing installations can be rebuild without problems
  • The covering is especially suited for locations where in case of an accident the resue service can be immediately at site
