近几年来,我国工业企业电气安装工程广泛采用了铝心导线,但铝线表面的氧化层机械强度大,耐温高以及接触导电能力差等,给铝导线同设备的连接增加了很大的困难。我公司自1958年以来,根据自己的情况,并参考国内外的一些资料,反复实践,初步找到了一些铝导线连接的较好操作方法和施工工具。在实践过程中,我们曾先后采取了电弧焊、镴 In recent years, aluminum core conductors have been widely used in electrical installations of industrial enterprises in China. However, the mechanical strength of the oxide layer on the surface of the aluminum wire is high, the temperature resistance is high, and the contact conductivity is poor, which increases the connection between the aluminum wire and the equipment. difficult. Since 1958, our company has, based on its own situation and with reference to some domestic and foreign data, repeatedly practiced and found some good methods of operation and construction tools for the connection of aluminum wires. In practice, we have successively adopted arc welding and welding.
