摘　　要：在35kV及以下电压等级输电线路中的导线,规格小、铝钢截面比值大,采用常规圆线结构的OPPC光缆很难达到理想匹配。文章介绍了导体结构为S型线的创新型OPPC光缆(S-OPPC光缆),具有结构紧凑、直径小、允许载流量大、弧垂特性好等特点,可以覆盖35kV及以下电压等级输电线路中常用LGJ导线规格。The conductors used for power transmission line with voltage level of 35 kV and below are generally of small size and big aluminium-steel ratio, which are difficult to match OPPC with normal round structure. In this paper, an innovative structure of OPPC with S-shaped aluminum wires is introduced with the features of compacted structure, small diameter, large allowable cun＇ent-carrying capacity and better tension-sag performance. This new structure of OPPC could cover normal LGJ conductors used for power transmission line with voltage level of 35 kV and below.
