1) strand breakage
断股
1.
Analysis of lightning-caused OPGW strand breakage on 500 kV HuiShan transmission line;
500kV惠汕乙线光纤复合架空地线雷击断股分析
2.
So the main causes for OPGW strand breakage form lightning are the structural design problems.
为避免落雷电弧烧坏光纤,国内外不少厂家在内、外层绞丝之间或与光单元之间设计留有一定空隙,给雷电流沿线传播在间隙上形成电位差、产生电弧创造了条件,一旦电弧产生,15~30 V就能维持,其产生的热量,使OPGW温度上升、强度下降,形成断股。
3.
Based on the analysis of optical fiber composite ground wire strand breakage cases and the test of mechanical performance,the reason of the optical fiber composite ground wire strand breakage is found out.
通过对光纤复合接地电缆断股事故的分析及机械性能试验,找出该光纤复合接地电缆断股的原因。

论述了OPGW雷击断股现象、断点分析及雷击断股原理,说明雷电先导形成的电弧高温是造成OPGW断股的外因,而OPGW股线(特别是铝合金线)的低熔点是造成断股的内因。
5) rusting broken strands
锈蚀断股
6) some strants of outlet line broken
引流断股
1.
Combined with electrical current thermal effect principle,the reasons of some strants of outlet line broken on tension pole in Hengshui 110 kV power transmission line are analyzed,and the prevention improvement are presented.
根据电流的热效应原理,分析了衡水110 kV送电线路耐张杆塔引流断股的原因,提出了预防改进措施。
补充资料：普通股每股净收益
普通股每股净收益——
普通股每股净收益是本年盈余与普通股流通股数的比值。其计算公式一般为：普通股每股净收益＝（净利－优先股股息）/发行在外的加权平均普通股股数。该指标反映普通股的获利水平，指标值越高，每一股份可得的利润越多，股东的投资效益越好，反之则越差。
