Cable tray seismic support expansion joint
The cable tray needs to be anchored at the support closest to the midpoint between the expansion joints with hold down clamps and secured by expansion guides at all other support locations. The expansion guides allow the cable tray to slide back and forth as it. 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. 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). In many high-seismicity applications, ladder tray is often preferred for primary distribution because it provides a strong structural form with relatively efficient. To handle what earthquakes do to cable trays, I follow some clear rules for Cable Trays Seismic Design: Stay Stable: I make sure my cable trays stay upright during an earthquake. Be Strong: I make sure my cable trays can hold a lot of weight.
