Resistant Cable Tray Models

Eaton B-Line Series with TOLCO Seismic Bracing This system is a fully integrated solution combining cable trays, bolted framing, and seismic bracing, pre-approved through third-party testing for seismic applications. It is suitable for both new construction and retrofit projects, offering faster installation and compliance with building codes across the U. S. and Canada.

Steel Ladder and Solid Bottom Trays Steel cable trays are commonly used in seismic zones due to their high strength and ductility. Ladder-type trays allow for flexible cable support and airflow, while solid-bottom trays provide additional protection for sensitive cables. Aluminum Cable Trays Aluminum trays are lightweight, corrosion-resistant, and suitable for seismic applications where weight reduction is critical.

They are often used in combination with seismic braces to maintain structural integrity during earthquakes.

Key Features for Seismic Resistance

Seismic Bracing: Braces, hold-down clamps, and guides are essential to prevent tray displacement during seismic events. Material Selection: Steel offers high strength, while aluminum provides lightweight and corrosion resistance. Connection Details: Bolted or welded connections must be designed to transfer seismic forces effectively, with proper pre-tensioning to prevent loosening.

Dynamic Response Considerations: Cable trays must account for vibrations and oscillations during earthquakes, with attention to natural frequency and damping to avoid resonance. Standards and TestingSeismic-resistant cable trays are designed according to building codes and standards such as the International Building Code (IBC) and National Electrical Code (NEC). Systems like the B-Line series undergo extensive dynamic testing to ensure structural integrity under seismic loads.

Summary

For seismic applications, Eaton B-Line series with TOLCO bracing is a leading choice, complemented by steel ladder, solid-bottom, and aluminum trays with appropriate seismic supports. Selection depends on project requirements, material preferences, and compliance with local seismic codes.
