What type of cable tray has good seismic resistance
Steel cable trays offer excellent strength and can withstand large seismic forces, but they are relatively heavy. Aluminum cable trays, on the other hand, are lightweight and corrosion-resistant, making them a popular choice in many applications. However, one often overlooked aspect is the seismic resistance of cable trays. Earthquakes and seismic events can cause severe damage to electrical infrastructure, including cable trays, leading to outages and even safety hazards. In many high-seismicity applications, ladder tray is often preferred for primary distribution because it provides a strong structural form with relatively efficient. 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. The tray should be able to resist the lateral and vertical forces imposed by the earthquake without collapsing or failing.
