What are seismic bracing supports for cable trays and busbars
Seismic bracing, typically made of high-strength metal, is key component specifically designed to enhance the stability and safety of cable tray systems during earthquakes. The assembly connects the structure such as a beam or ceiling, to a brace member which could be cable, channel, or pipe to a non-structural support, such as pipe, trapeze, cable tray, duct, and more. 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. If these. ng with secure and reliable data storage. The broad nVent Data & Networking product portfolio, combined with design and project support, enables you to specify and deploy your project on time to ensure data and network i he zone in which the building is located.
