摘　　要：按照IEC60794和DL/T832标准,对不同参数类型的OPGW进行了雷击试验,分析总结了OPGW外层绞线单丝直径、绞线材料、雷击转移电荷库仑数、张力、雷电参数等对OPGW雷击断股的影响。在此基础上提出,采用较大直径外层绞线和铝包钢材料外层绞线的OPGW可有效防止其遭雷击断股。According to IEC 60794 and DL/T 832 standards, lightning tests are taken on OPGW samples with different types and parameters. The influences of diameter and material of outer-layer strands, electric charge quantity of lightning, strength and lightning parameters on the break of OPGW outer-layer strands caused by lightning are discussed and analyzed. Based on this, in order to prevent the break of out-layer strands caused by lightning, OPGWs with bigger diameter and ACS material outer-layer strands are preferred.
