Cable and cable tray resonance

By moving the supports closer, the system becomes too tight to bounce easily. In a normal building, you might only use a clamp at every other support. 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). The main impact is that resonances can occur at much lower requencies than when only overhead lines are present. Two illustrative case studies are presented: one for a 275-kV cable, one for a 400 kV cable in combination with a 132-kV capacitor. This guide covers how to select heavy-duty materials, use vibration-damping accessories, and implement locking hardware to ensure your system meets safety standards and avoids costly downtime. The floor response extracted by. The major conclusion from the study is that cable trays are an integral part of the ground structure (actually, it forms the ground if correctly done; nothing else is needed), which can perform as a shielding structure for the enclosed electronic systems. The major quality parameter is the.
