Technical characteristics of copper and brass strip application

Mar 10, 2023

What are the technical characteristics of brass tape applications? Rectangular copper bar is characterized by large width, small thickness, small cross-sectional area and large surface area. Therefore, according to the current skin effect, the carrying capacity is larger than that of the standard rectangular copper bar with the same cross-sectional area. Compared with the standard rectangular copper bar with the same cross-sectional area, the mechanical strength is relatively small and the impedance of the bus bar is relatively large. Larger busbar impedance increases the voltage loss on the busbar.

Manufacturers through the copper and brass strip processing is very thin, so as to save the amount of copper, improve the load, in a certain technical rationality.

The copper bar in dense busbar products is closely laminated, and there is no air gap between the copper and brass strip, which is more conducive to the heat dissipation of the copper bar. Under the same specifications, the load capacity of the copper bar is larger than that of the bare laid in the air. At present, there is no load standard of each specification copper bar used in dense busbar slot, which objectively causes difficulties in reviewing whether the core material used in busbar products is sufficient.

At present, there are two objective and recognized methods for reviewing copper and brass strip and red copper belt products: one is to review the 3C certification and type test report; Second, samples are immediately taken and sent to third party testing institutions for testing. I hope Luoyang gem copper industry for you to collect these information will be helpful!
