Fire-fighting cable trays inside vertical shafts
Technical guide to firestopping cable tray and slab penetrations in electrical shafts; specifies materials, packing limits, waterstop heights and installation sequence. Where cables pass through shafts, walls, slabs, or enter electrical panels or cabinets, openings shall be tightly sealed with firestopping materials in accordance with. These cables run inside large metal trays (Cable Trays) or drop vertically through enclosed channels (Electrical Shafts / Risers). Every time these channels pierce fire-rated walls or slabs, they create enormous holes (much larger than a single pipe). This document, based on national standards such as GB 50303 “Code for Acceptance of. Cable tray installation must comply with specific technical standards to ensure electrical safety, system reliability, and long-term maintainability.
