| 摘 要： | 就IEC 60794．4．1标准所描述的雷击试验要求，对不同OPGW光缆设计进行了研究，并分析了雷击对不同OPGW缆型的影响。提高连续电流——组成部分C(最具破坏性的部分)的电荷转移量，光缆的残余抗拉强度将随之降低。当电荷转移量大于100C时，光缆被损坏程度更多地取决于光缆的直径而不是外层绞线的直径。试验结果表明，为了设计出可靠并经济的OPGW光缆，我们必须综合考虑OPGW的机械性能和依据安装地的年雷暴日水平所必需的抗雷击性能。

| Abstract: | The present paper investigates the effects of the lightning waveforms described in IEC 60794-4-1 on various OPGW designs. Increasing the charge transfer level of the continuing current component, the most damaging one, the residual breaking strength of the cable decreases. The damage on the cable for charge transfer is larger than 100 C seems to be stronger dependent on the cable diameter more than on wire diameter. The results of this experimental work show that we have to consider both mechanical and lightning resistance together with Keraunic levels of the area of installation in order to design reliable and cost effective OPGW. |
