What are the requirements for copper bus installation
18
1. When assembling the copper busbar, you must wear gloves to prevent fingerprints and stains on the surface. 3. Fasteners for copper bus connection use galvanized bolts/screws, nuts and washers that meet national standards. 3. The length of the combined screw should be considered to be 2～5mm outside the nut after the screw is tightened, and the length of the hexagonal head bolt/half-round square neck bolt should be considered after the bolt is tightened. The thread should be 5～8mm outside the nut. Too long or too short. 4. The penetration direction of bolts is generally from bottom to top, from back to front, from left to right, as far as possible to achieve uniformity.When the copper bar is placed horizontally, the connecting bolts and nuts should be tightened from bottom to top. In other cases, the nuts should be installed on the side that is convenient for maintenance.. 5. There must be flat washers on both sides of the bolts connecting t2 copper bars, and spring washers or lock washers should be added to the nut side.The washers of adjacent bolts should have a clear distance of more than 3mm to prevent heating of the magnetic circuit. 6. Under normal circumstances, it is not suitable for three copper bars to be overlapped at one place, according to the requirements of design and process documents.. 7. The contact surface of the copper bar should be tightly connected. The connecting bolts should be tightened with a torque wrench to confirm and mark, and the connecting combination screws should be tightened with a torque batch to confirm and mark. The tightening torque value should meet the requirements of the “Thread Tightening Process Specification”. 8. The price of copper row The installation of copper row should be smooth and beautiful, and when installing the copper row: horizontal section: the height error of the two supporting points is not more than 3mm, and the total length is not more than 10mm.Vertical section: the vertical error of the two supporting points is not more than 2mm, and the total length is not more than 5mm.Spacing: The spacing of the parallel parts should be uniform, and the error should not be greater than 5mm. 9. When two or more rectangular copper bars are connected in parallel, ensure that the gap between the parallel copper bars is not less than the thickness to facilitate heat dissipation..
