Electrical continuity provides safety to people and property, and plays an essential role in the EMC performance
Electrical continuity provides safety to people and property, and plays an essential role in the EMC performance. The resistance of wire mesh cable tray usually does not exceed 5mΩ/m for straight sections, and does not exceed 1 mΩ for connecting accessories. These are much better than standard IEC 61537 states that the cable tray systems impedances shall not exceed 50 mΩ across the joint and 5 mΩ per meter without the joint.
When the wire mesh cable tray systems are integrated into equipotential earthing network, it can help electrical installations achieve excellent EMC levels. Besides reducing crosstalk, the open structure makes it easy to ensure correct separation by visual inspection.
