Some Key Problems in Design of OPGW Line

文章针对架空地线复合光缆(OPGW)设计中的几个问题,详细介绍了OPGW选型时应注意气象、温度、短路电流及耐雷水平等多方面因素,并需考虑地线匹配,光缆分盘和预留长度、初伸长处理以及防振等问题,提出了相应的解决办法和建议。

According to some problems in design of OPGW, it is pointed out that the various factors such as meteorology, temperature, short - circuit current and lightning impulse withstand level should be paid more attention when OPGW type selecting, and be considered the problems such as the matching earth wire, the reserve length of cable box, first elongation handling as well as anti - vibration. The suggestions and corresponding method for solving problems are put forward.
