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 panShorter switch-off period of the transformer
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
