FIELD: cable penetrations.
SUBSTANCE: cable penetration is a mineral wool filler, with which, at least to the embedding depth, a hole with a depth of at least 150 mm in the building structure is filled, and refractory fibre, with which the cables outside the hole is wrapped over the length of the section of the refractory fibre placement on the cable, wherein the refractory fibre is also at least partially arranged on the outer surface of the building structure; wherein: hole is filled at least to the depth of embedding with fire-retardant sealant; fire-retardant coating is applied on at least: over the length of the section of application of the fire-retardant coating on the cable outside the hole; and/or surface of building structure in places of refractory fibre adjoining; and/or cable-facing surface of refractory fibre; and/or the surface of the refractory fibre facing away from the cable; and/or the surface of the refractory fibre facing the surface of the building structure; and/or the refractory fibre surface facing away from the building structure surface.
EFFECT: increasing the fire resistance of cable penetration.
