    Abstract Based on a comparison between the corrosion resistance of copper and aluminum materials under different working conditions，this paper points out that both the two kinds of materials have the same good performance in corrosion resistance as long as the cables are properly installed.

    Key words　Copper cable　Aluminum cable　Chemical corrosion　Electrochemical corrosion　Multi-factor corrossion

    摘　要　比较铜、铝两种材料在不同工况下的耐腐蚀表现。仅就耐腐蚀能力而言，铜或铝质电缆只要正确安装，都同样具有优异的耐腐蚀性能。

    关键词　铜电缆　铝电缆　化学腐蚀　电化学腐蚀　多因素腐蚀
