FIELD: building.
SUBSTANCE: proposed technical solution relates to cable penetrations and can be used to ensure passive fire protection of cabling and other building structures at nuclear and thermal power plants. Cable penetration and mounting set therefor constitute mineral wool filler used to fill a hole in the building structure at least partially, wherein the filler is covered on the outside with a fire-protective coating also applied to at least one cable on each side outside of the hole, wherein at points of contact of the cable inside the hole the filler is covered with a fire-resistant sealant, the fire-protective coating is produced by preparing from a set for preparing a fire-protective bloating cold-curable composition.
EFFECT: invention provides the required limits of fire resistance, structural simplicity, ease of installation, and low consumption of materials, in particular, fire-protective coating.
