SYSTEM FOR FIRE PROTECTION OF A CABLE OR A CABLE LINE Russian patent published in 2021 - IPC E04B1/94 

FIELD: firefighting.

SUBSTANCE: proposed technical solution relates to fire protection systems and is intended, e.g., for fire protection of cabling, including that at nuclear power plants (NPPs) and thermal power plants (TPPs), increasing the fire resistance limit of load-bearing metal structures, increasing the fire resistance limit of ventilation ducts, including those at NPPs and TPPs, finishing fire-resistant structures of industrial and construction facilities, including those at NPPs and TPPs. The technical problem solved by the claimed technical solution is creation of a fire protection system for a cable or cable lines and supporting structures thereof, studs and channels, as well as creation of individual elements of the system, providing simple and quick assembly, increased fire protection of the cabling, security of operation, as well as possibility of quick disassembly of the elements to allow for repair work on the cable line without the need to destroy the fire protection system. Another technical problem solved by the claimed technical solution is expansion of the range of technical means for a certain purpose, namely, systems for fire protection of cable lines and individual elements thereof.

EFFECT: simplification of the process of assembly of the elements of the system for fire protection of a cable or cable lines, as a consequence, increase in the speed of assembly of the elements of the system for fire protection of cable lines, as a consequence, reduction in the duration of assembly of the elements of the system for fire protection of cable lines; as well as increase in the fire protection of the cabling as a whole, and, as a consequence, increase in the operational security of the cabling; as well as simplification of disassembly of the elements of the system for fire protection of cable lines, as a consequence, acceleration of disassembly of the elements of the system for fire protection of cable lines, as a consequence, reduction in the duration of assembly of the elements of the system for fire protection of cable lines, as a consequence, increase in the maintainability of the cabling as a whole.
