Example Embodiment
[0030] Example 1
[0031] This embodiment provides a low-impedance high-intensity lighting busway, which includes an upper cover plate, a lower cover plate, two side plates, and a bus bar. The upper cover plate, the lower cover plate and the two side plates enclose a line-containing cavity, and the bus bar Set in the line-containing cavity, the upper cover, lower cover and two side plates are all made of the following mass percentages of raw materials: C: 0.35%, Cr: 2.26%, Si: 0.95%, Zn: 0.66%, Cu : 2.34%, W: 0.13%, Mn: 0.35%, Mg: 0.93%, rare earth elements: 1.56%, the balance is Al and unavoidable impurities.
[0032] Among them, rare earth elements are composed of La, Nd, Ce, and Tb in a mass ratio of 1:2:1:1.
[0033] The preparation method of the upper cover plate, the lower cover plate and the side plates in this embodiment includes the following steps:
[0034] S1: Preheat the smelting furnace. When the preheating temperature is reached, put Al into the smelting furnace. Adjust...
