Westinghouse AP1000 Design Control Document Rev. 19
The AP1000 cable tray system design requires no sprayed-on material for fire protection. Cable ties are provided at spacing greater
Spacing of seismic-resistant cable tray hangers
Spacing must be at least every 30'. In regions prone to seismic activity, ensuring that your cable tray system is capable of withstanding such events is vital. Cable tray runs in seismic zones need more than normal hanger spacing. A standard trapeze support carries gravity load; it does not reliably stop lateral sway, longitudinal movement, anchor pullout, or cable spill during ground motion. For over 60 years, the mechanical, electrical, and fire protection trades have relied on TOLCO seismic bracing solutions. Predrilled tabs allow attachment directly to concrete deck.
