Technical Requirements for Seismic Strengthening of Cable Trays
It is a core design requirement for nonstructural electrical systems in high-seismicity projects. The best outcomes come from combining the right tray type, the right bracing and attachment details, the right movement allowances, and the right documentation. Before diving deeper into the specifics, it's important to understand the various factors that. This appendix provides the design criteria for seismic Category I cable trays and their supports. Dead load includes the weight of the cable trays, their supports and the cables. Requests for copies of this report should be directed to the EPRI Distribution Center, 207 Coggins Drive, P. Box 23205, Pleasant Hill, CA 94523, (510) 934-4212. INTRODUCTION large telecommunication company embarked on a program that included building a series of telecommunications facilities in the Seattle, Washington area. High-seismicity projects place much greater demands on cable tray systems than ordinary installations.

What are the specifications for network cable trays
In practice, cable tray dimensions are a system of interrelated measurements —width, depth, length, and material thickness—that directly affect cable fill compliance, heat dissipation, structural loading, and long-term expandability. All illustrations, descriptions and technical information included in this document are provided as indications and can cable trays are equivalent. From an engineering standpoint, cable tray dimensions are not. maintain spacing or to keep cables in place when the tray is ect the minimum bend ra-dius for cables as they exit the bottom of the cable tray. A rung spacing of 6 to 9 inches (150 to 230 mm) is preferable when the cable tray cont d for instrumentation and control applications that require. Cable trays play a vital role in supporting electrical cables and wires in commercial, industrial, and utility installations. A cable tray system makes it easier to upgrade, expand, reconfigure, or move networks by supporting and protecting both power & signal wires. This tray is stocked in a range of Pre-Galv and Hot Dip Galv finishes, which can also be powder coated and.
