Abstract Both copper and aluminum can conduct electricity，but their resistivity is different. The resistivity of aluminum alloy conductor is lower than that of aluminum conductor，since it is made by adding relevant element into aluminum conductor. The author thinks，with the development and perfection of the manufacturing engineering，aluminum alloy cable can be used as distribution main and branch main cable in residential building or residential district.

摘　要　铜与铝导体均具有导电能力，两者电阻率不同；铝合金导体是在铝导体中加入了相关元素，使其电阻率较纯铝导体低。随着制造工艺的完善，作者认为铝合金电缆是可以用作住宅建筑或住宅小区的配电干线及分支主干线的。
