  • Which cable tray seismic support is better

    Which cable tray seismic support is better

    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. A standard trapeze support carries gravity load; it does not reliably stop lateral sway, longitudinal movement, anchor pullout, or cable spill during ground motion. A coordinated seismic bracing system uses strut channels. In regions prone to seismic activity, ensuring that your cable tray system is capable of withstanding such events is vital. They should not fall down or bend too much. INTRODUCTION large telecommunication company embarked on a program that included building a series of telecommunications facilities in the Seattle, Washington area.
