Hot㓎 zinc bridge frame grounding strip
Thread Content
For the hot and cold zinc metal cable trays designed by the design institute, after installation, a galvanized flat iron 40 meters in length was installed inside the trays as the grounding main line. Is it necessary?
It is necessary to include a grounding main in the design of hot zinc metal cable trays. Since metal cable trays can generate static electricity during use, and electrical faults such as lightning strikes may occur, failing to install a grounding main line means that these charges cannot be discharged in a timely manner, which could pose a threat to both human safety and equipment safety. Therefore, to ensure electrical safety, it is recommended to install a grounding main within the cable tray. .
The normal grounding trunk line is not located inside the cable tray; it is placed outside of it. The catalog provides specific instructions on how to secure it to the cable tray. Theoretically, it is possible to use the cable tray itself as a grounding element, but this requires that the resistance of the connections between sections of the cable tray meet the specified requirements; it is necessary to verify that each pair of sections is properly connected. In practice, this approach is too cumbersome, so it is more convenient to simply use flat steel bars that run throughout the entire length.
I manufacture cable trays; isn’t it possible to connect two cable trays using jumper wires? :lol
It is not necessary to lay any wires; the metal components used for mounting brackets can be utilized, or jumper wires can be used for grounding, or the connection plates can be secured with at least two hot-dip galvanized nuts.
