Electrical Continuity
Thus cable trays must connect with each other by using couplers. The standard IEC 61537 states that the cable tray systems impedances shall not exceed 50 mΩ

And the connection of the sections of the ducts is carried out using connectors and bolts. en completely installed, without damage either to conductors orstructural 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. Connecting cable trays correctly is essential for system safety, load stability, and long-term performance. This is the role of the cable tray system—a structured framework designed to support and organize insulated electrical cables, control cables, and communication lines.
