Infrastructure Application
Cable Tray Tunnel Fixing
Heavy-duty cable ties for cable tray and tunnel installations. Power, control, and communication cables routed through trays and tunnels require ties that handle continuous static loads, fire safety requirements, and long service intervals.
Why Cable Tray Tunnel Fixing Needs Specialized Cable Ties
Cable trays and tunnels carry critical infrastructure — power distribution, plant controls, emergency systems, data backbones. Cables in these installations are heavy, densely packed, and expected to remain secured for decades without maintenance access. Ties must handle significant static loads without creep or relaxation, and meet fire safety codes for confined tunnel spaces.
Our tray and tunnel-grade ties feature extra-heavy tensile ratings and wide bodies for superior load distribution. Flame-retardant grades meet UL94 V-0 for fire-critical tunnel installations. Stainless steel ties provide indefinite service life in inaccessible locations where replacement is impractical. High-temperature grades support derated cable installations operating at elevated temperatures.

Key Challenges in Cable Tray Tunnel Fixing
Understanding the specific demands helps select the right cable tie for each application.
Long-Term Static Load
Cables in vertical tray runs exert continuous downward force. Ties must resist creep deformation over decades — a phenomenon where polymers slowly stretch under constant load, eventually losing bundle tension.
Fire Safety in Tunnels
Confined cable tunnels require strict fire performance. Flame-retardant ties self-extinguish and do not contribute fuel load. Stainless steel ties are inherently non-combustible for maximum fire safety.
No-Access Installations
Buried tunnels and sealed trays may never be accessed after installation. Stainless steel ties provide the indefinite service life needed for permanent infrastructure — no polymer degradation, no UV concern, no replacement.
