How to Select Seismic-Resistant Cable Tray Supports
Engineers typically use seismic design codes and standards to determine the appropriate design parameters for cable trays based on the seismic hazard level of the site. However, one often overlooked aspect is the seismic resistance of cable trays. During an earthquake, cable trays are exposed not only to gravity loads and normal service loads, but also to lateral movement, vertical acceleration, vibration, and building drift. Cablofil adapts to the most complex configurations, and its structure gives maximum strength for minimum weight. Copyright @ 1991 Electric Power Research Institute, Inc.
