Cable tray is a commonly used cable support used for cable routing and protection. Grounding is a very important step in the wiring process of cable bridges in Shandong Province. The following are precautions to be taken when grounding:
Selection of grounding point: The grounding point should be located on the cable tray at a distance that is relatively far away and has a large number of cables, and it should be connected to the grounding wire of the power supply.
Selection of grounding wire: The grounding wire should use copper wire or copper tape with good conductivity, corrosion resistance, and oxidation resistance. The wire diameter should match the number of cables and current load.
Treatment of grounding points: The grounding points should be clean, dry, and bright, and impurities such as oxides and oil stains on the surface of the grounding points should be removed to ensure the quality and reliability of the grounding points.
Fixation of grounding points: The grounding wire should be firmly fixed to avoid falling off or loosening during use, and attention should be paid to avoid mutual interference between the grounding wire and other cables or equipment.
Test of ground wire: After the installation of the ground wire, a test should be conducted to measure the ground resistance to ensure the effectiveness and safety of the ground.
During the wiring process of cable trays, grounding is a very important link, and attention needs to be paid to matters such as point selection, line selection, handling, fixation, and testing to ensure the quality and reliability of grounding and ensure the safety of equipment and personnel.
