联邦德国1989年2月出版的《铝》杂志报道:电气工业进行的高速革新要求不断地发展电气工业用的专门铝加工材料.室外架空电缆以铝代铜已开始多年.电解厂和再生铝冶炼厂的高电流母线也使用铝.铸造和锻造的铝管形夹钳和其他元件用于高压开关设备. 现在用挤压法可以生产直径达600毫米的铝电机壳.它的壁很薄,比铸造壳体的散热性好,并且由于尺寸精确,公差小,不需扩孔加工就能把定子压层元件压装到预定位置. 在大功率电气设备上,随着电功率增加,要分散元件上不断增加的热量,发展了高性能的具有整体翅片的铝散热器.
The “Aluminum” magazine of the Federal Republic of Germany, published in February 1989, reports that the rapid innovation in the electrical industry calls for the continuous development of specialized aluminum processing materials for the electrical industry. Aluminum overhead copper has been used for outdoor aerial cables for many years. Electrolysis plants and reclaimed aluminum smelters The high-current busbar of the plant also uses aluminum. Cast-forged and forged aluminum tubular clamps and other components are used for high-voltage switchgear. Aluminum extrusion can now produce 600 mm diameter aluminum housings with thin walls, Heat dissipation than the casting shell, and due to the size of the precise, small tolerances, without expanding the stator pressure lamination components can be pressed to a predetermined position in the high-power electrical equipment, as the electric power increases, to disperse the components On the growing heat, the development of high-performance with the overall fin aluminum radiator.
