FLAME RETARDANT CASING FOR THE CHANNEL Russian patent published in 2021 - IPC E04B1/94 

FIELD: fire protection.

SUBSTANCE: proposed technical solution relates to fire protection systems and is intended, for example, for fire protection of cable facilities, including at nuclear power plants and thermal power plants, increasing the fire resistance limit of load-bearing metal structures, increasing the fire resistance limit of ventilation ducts, including at nuclear power plants and thermal power plants, finishing fire-resistant structures of industrial and construction facilities, including at nuclear power plants and thermal power plants. The technical problem solved by the claimed technical solution is the creation of a fire protection system for cables or cable lines and its supporting structures - studs and channels, as well as the creation of individual elements of this system that provide simple and quick installation, increased fire protection of cable facilities, reliability of operation, as well as the ability to quickly dismantle elements to ensure 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 the expansion of the arsenal of technical means for a certain purpose, namely fire protection systems for cable lines and their individual elements.

EFFECT: simplifying the installation process of the elements of the fire protection system of cables or cable lines, as a consequence, an increase in the speed of installation of the elements of the fire protection system of cable lines, as a consequence, a reduction in the duration time of installation of the elements of the fire protection system of cable lines; as well as an increase in the fire protection of the cable system as a whole, and, as a consequence, an increase in the operational reliability of the cable system; as well as simplifying the dismantling of elements of the fire protection system of cable lines, as a consequence, accelerating the dismantling of elements of the fire protection system of cable lines, as a consequence, reducing the duration of the installation time of elements of the fire protection system of cable lines, as a consequence, increasing the maintainability of the cable system as a whole.
