BN-OF

The covering of transformer basins BN-OF is comprised of BN-O type sections. Strips of flat material 30 x 2 mm are welded to the sheet section from below. Both open parts are closed with flat material and if length is larger than 2000 mm, they are provided with weld-on round bar rods 8 mm x 25 mm.

In case of a fire, it will be temporarily localized in the catch basin until firemen arrive.
