BN-OF (Fire-Retarding Covering Type)

OVERVIEW

Transformers in outdoor installations are an important part of our industry to grant the electric power supply. We use transformer oil as cooling for these installation parts. External influences (f. ex. lightning) and there could damage the transformer by the free-flowing oil could pollute the groundwater. Therefore there is a pan installed underneath the transformer wherein the oil and rain or fire water can be collected in case of disturbances and leakages.

To suffocate the flames in case of a fire in the collecting pan, use transformer coverings.

 

TYPE BN-OF

Fire-retarding coating BN-OF was form as a substitute to the traditional coverings. The principle is the well-known perforated metal plank type BN-O, which Lichtgitter is manufacturing and distributing for quite some years. Leading type BN-OF is suitable as a covering for the grease gathering pans beneath the transformer units. In case of fire the flames are prevented by the restricted air permeability, but not squelched.
