    • A concentric stranded conductor having a concentric strand having multiple bunched strands twisted together, in which each bunched strand has multiple single wires twisted together;
      wherein the concentric stranded conductor has a central core bunched strand (5) and a first-layer concentric strand (11) having multiple first-layer bunched strands (9) twisted together around the central core bunched strand (5);
      wherein a twist pitch of the central core bunched strand (5) is from 8 to 70 times an outer strands distance thereof, a twist pitch of the first-layer concentric strand (11) is from 8 to 30 times an outer strands distance thereof, a difference between a twist angle of the central core bunched strand (5) and a sum of twist angles of the first-layer bunched strands (9) and first-layer concentric strand (11) is 15 degrees or less, and each single wire is made of an aluminum or aluminum alloy, having elongation of 2% or more.
    • 一种具有同心绞合线的同心绞合导体,所述同心绞合线具有绞合在一起的多根绞合绞合线,其中每根绞合绞合线具有绞合在一起的多根单根绞合线; 其中所述同心绞合导体具有中央芯束线股(5)和第一层同心绞线(11),所述第一层同心绞线具有围绕所述中心芯束线绞合线(5)捻合在一起的多个第一层束线股(9); 其特征在于,所述中心芯线束股(5)的扭绞节距为其外股线距离的8倍至70倍,所述第一层同心股线(11)的扭绞节距为其外股线距离的8至30倍, 中心芯线聚束线(5)的扭转角与第一层聚束线(9)和第一层同心线(11)的扭转角之和之差为15度或更小,并且每根单线 由具有2%或更多的伸长率的铝或铝合金制成。
