What are the requirements for grounding galvanized cable tray maker? If the cables laid in the cable tray are already five cores, is grounding still necessary? If so, how should it be done? If it is a 4-core product, how should grounding be done? Should flat steel be laid along the cable tray or should wires be used to connect the cable tray to equipotential bonding at both ends of the cable tray? These are all problems. So what should we pay attention to when grounding the galvanized cable tray maker?
Grounding requirements for bridge frames
The grounding method for the bridge frame should be to ground the main reinforcing bars with a copper-plastic wire no less than 2.5mm thick.
2. The grounding resistance of each cabinet and chassis shall not exceed 1 ohm.
3. The equipment in the computer room adopts two independent grounding methods for the bridge frame, namely the combined grounding of the working grounding. The working grounding resistance shall not exceed 4 ohms, and the combined grounding resistance shall not exceed 1 ohm.
Attention should be paid during the debugging stage:
It is strictly prohibited to power on immediately without inspection.
2. Strictly check whether the equipment installation and line laying of each sub-item project are in accordance with the drawings and documents.
3. Check the installation and wiring conditions of each network device, PBX device and information point one by one. If there are any non-conformities, fill in the quality feedback form and make corresponding records.
After all the equipment and points have been checked for accuracy, power on each device and point one by one for testing.
5. System debugging can only be carried out after the power-on test. And keep good records.
