What are the requirements for copper bar installation?

1. The fasteners used for copper bar connection are galvanized bolts/screws, nuts and washers in accordance with national standards.

2. The length of the combination screw should consider that the screw can expose 2 ~ 5mm outside the nut after fastening the screw, and the length of the hexagon bolt/half round head square neck bolt should consider that the screw can expose 5 ~ 8mm outside the nut after fastening the bolt, and should not be too long or too short.

3, bolt through the direction of the general situation from bottom to top, from back to front, from left to right, as far as possible to achieve unity. When the copper bar is placed horizontally, the bolts and nuts should be tightened from bottom to top. In other cases, the nuts should be installed on the maintenance side.

4, connecting copper bolts on both sides should have flat washers, nut side to add spring washers or lock washers. Adjacent bolt washers should have a net distance of more than 3mm to prevent the formation of magnetic circuit heating.

5, under normal circumstances, it is not suitable to lap three copper rows in one place, according to the requirements of design and process documents.

6. The contact surface of Shenyang copper bar should be tightly connected, the connecting bolts should be confirmed and marked by torque violence, and the connecting combination screws should be confirmed and marked by torque batch, and the tightening torque value should meet the requirements.

7, copper bar installation should be smooth and beautiful, and copper bar installation: horizontal section: the height error of the two support points is not more than 3mm, the full length is not more than 10mm. Vertical section: the vertical error of two support points shall not be greater than 2mm, and the full length shall not be greater than 5mm. Spacing: the spacing of parallel parts should be uniform and the error is not more than 5mm.

8. When two or more rectangular copper bars are in parallel, the gap between the parallel copper bars should be no less than the thickness to facilitate heat dissipation.

9. Zoomlion reminds you that shenyang copper bar assembly must wear gloves to prevent hand prints and stains on the surface.
