The point where cable trays enter a building can be vulnerable to wind and rainwater ingress, so careful planning and effective weatherproofing of the building penetration are critical. The effective weatherproofing of cable trays helps to keep weather out, preventing damage to the building. We test cable trays for water and dust protection in two main ways: Laboratory Testing: We do this in a controlled lab. We simulate various conditions to thoroughly check the tray's performance. We look at how it performs in its. en completely installed, without damage either to conductors or structural system use maintain spacing or to keep cables in place when the tray is ect the minimum bend ra-dius for cables as they exit the bottom of the cable tray. When properly selected and installed, cable trays simplify routing, improve accessibility, and support future expansion while.
