The most commonly used materials for fire-proof separation of cable trays are fire-proof boards, fire-proof coatings, fire-proof bags, fire-proof mud, and TST CABLES alternative products such as light fire-proof sections. Therefore, it is crucial to set up fire-blocking sections (fire sections/fire partitions) on cable trays and select appropriate fire-blocking sections (fire sections/fire partitions) materials. * Two (2) sticks of moldable putty (part number FSP-MPS) are also needed for each opening. 7 products are successfully used to protect cables in high-rise buildings. The installation of fire-blocking partitions or fire-blocking devices (also known as “fire-blocking sections” below) can effectively isolate the fire source when a fire occurs and protect the cables from fire. According to the requirements of national standards GB50217 and GB50872, fire-blocking.
