摘　　要：通过实际计算导线受到张力时钢线和铝线的受力分配情况和安全系数,提出在重冰区计算导线过载能力时,应考虑铝线的受力情况,保证铝线的最小安全系数,优先考虑采用钢芯铝合金绞线。The article propose that while calculating the ACSR overload capacity in heavy ice area should considerate aluminum conductor stress, and give the suggestion to use aluminum alloy conductors steel-reinforced in heavy ice area.

关 键 词：钢芯铝绞线 应力 重冰区 过载能力
