Equipotential bonding conductors in cable trays
The equipotential bonding system is mounted on cable tray systems. All conductive system parts and electrical equipment are integrated in the Ex equipotential bonding by means of equipotential bonding plates and clamps as well as a closed ring equipotential bonding conductor. These do not guarantee the required safe, consistent and permanently effective electrical connection. Four different options are available for this, making it possible to select based on installation conditions and environment. A continuous tin-plated copper cable is guided directly in the cable. Supplementary bonding is the practice of connecting two conductive simultaneously accessible parts together to reduce the potential difference between the parts.
