The fire rating of trough-type fire-resistant cable trays is primarily defined by fire endurance —the duration for which structural integrity and electrical circuit continuity are maintained under standard fire exposure. In China, the authoritative governing standard is GB 29415-2013 Fire-Resistant. Cable trays, or carrier trays, are mechanical support systems for cables. They provide a robust structural that accommodates and safely transports cables from one point to another. Cable trays provide.
