Cable tray deformation and sinking
This article delves into the reasons behind cable tray deformation, explores preventive measures, and offers practical advice for ensuring proper installation to maintain the integrity of the tray system. Cable trays are an essential part of electrical installations in buildings, providing support and protection for various cables and wires. Such deformations can lead to reduced functionality, safety hazards, and shortened service. Cable tray and conduit systems have consistently performed well at conventional power and industrial facilities subjected to past strong-motion earthquakes larger than eastern U. plant safe shutdown earthquakes (1). This is so even though the systems are typically not designed for earthquake. us-trations without notice.
