Rainwater seeping into the cable tray

If water fills the conduit due to rain or flooding, it can seep into the cable through these minor breaches. For environments where cables are pulled through conduits, a gel-filled core offers an extra layer of security. Cable tray design is the first step in ensuring an effective drainage system. Imagine you're installing a security camera on an exterior wall—if rain or water spray reaches the cable end near the camera, there's a risk that moisture will enter at that connection point and travel down. 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 eff...
