1. The delivered copper busbar should be smooth and flat, free of cracks, wrinkles, inclusions and deformation. 2. The installation screw holes of various metal components should not be gas welding cutting holes or electric welding blow holes. 3. When the copper bus bar is connected to the copper bus bar, and the copper bus bar is connected to the electrical wiring terminal, it can be directly connected in a dry room. 4. When the rectangular bus is connected by bolts, the distance between the connection and the edge of the supporting splint of the pillar insulator shall not be less than 50 mm. 5. The force of the bolts should be even, and the electrical wiring terminals should not be subject to additional stress. 6. The contact surface of the busbar should be tightly connected, and the connecting bolts should be tightened with a torque wrench. The tightening torque value should meet the following table: 7. The busbar should meet the following requirements when fixing the busbar on the pillar insulator: A. Between the busbar fixing and the pillar insulator The fixing should be flat and firm, and the bus bar supported by it should not be subjected to additional stress.Copper bar B. When the bus bar is placed upright, the upper pressure plate and the bus bar maintain a clearance of 1.5 mm to 2.0 mm. C. The fixed dead point of the busbar on the pillar insulator should be set at each section, and it should be located at the full length or the midpoint of the two busbar expansion joints.. 8. The busbar fixing device should be free of edges, corners and burrs. 9. A soft connection should be adopted at the connection between the bus bar and the equipment, and the cross section of the connecting wire should not be less than the bus bar section. 10. Insulators should be inspected before installation, and the porcelain parts should be intact and free of cracks. 11. Pillar insulators installed on the same plane or vertical should be on the same plane. 12. The installation center lines of the pillar insulators of the busbar straight section should be on the same straight line. 13. The copper busbar must be tinned before installation (busbar installed in a humid environment), and a wire brush should be used to clean the oxide and dirt on the busbar before tinning.. 14. When installing copper bus bars, a layer of conductive paste must be evenly coated on the contact point of the two bus bars. 15. The construction personnel who install the copper busbar should do a good job in the protection of labor supplies, and do a good job in the ventilation of the construction site, and adopt an air extraction device. 16. Construction garbage should be cleaned up in time and placed neatly. 17. When constructing at high altitude, wear safety protection equipment or erect scaffolding.
