Fire-resistant cable penetration of this type is used to restore the fire resistance limit of building structures with standardized fire resistance limits, preventing the spread of combustion into adjoining rooms within the standardized period in CAZ and FAZ, as well as between CAZ and FAZ.

Fire resistance limit SRE-UL(1)ASVS — up to IET90;

This material is resistant to high temperatures: in case of fire, it prevents the cable from burning through the penetration, prevents the spread of fire, temperature, and smoke, and prevents the burning of the cable inside cable penetration and behind it. The material is resistant to radiation and decontamination solutions.

The penetration is used for openings of rectangular cross-sections when laying cables through the building structure, as well as for openings of circular cross-sections, with cable filling up to 60% and more. It is used in the case of multiple subsequent modifications of the penetration or frequent cable routing if a high speed of installation is required.
