Fireproofing of Long-Span Cable Trays in Bhutan
Cable trays and busways at floor level or at slab penetrations shall have a waterstop no less than 50 mm in height. At slab penetrations, provide 20–30 mm of firestopping and install a fire-support plate at the top. Scope: Firestopping for busway, cable trays, cables, and trunking passing through walls in enclosed electrical installations. FyreWrap® Cable Insulation from Alkegen is a thin, flexible insulation wrap designed to provide fire protective enclosures around cable trays and conduit. At Kiash Electricals, we recognize the utmost need for safe and judicious cable handling in any installation in Bhutan. Engineered for continuous monitoring and early warning, our cable-based detection system is ideal for protecting cable trays—whether single-tier, multi-tier, or densely packed. Cable tray installation must comply with specific technical standards to ensure electrical safety, system reliability, and long-term maintainability.
