  大量本地猛禽等鸟类栖息的窝是在横臂的顶部,缩短与树枝的干弧距离,正在成为导致绝缘子故障的主要原因。寻求解决这类问题通常需要更多的'开箱即用'的思想而不是选择更合适的绝缘子设计,才是该服务环境中使用的更合理的方法。 由于与鸟类互动并不是绝缘体性能问题,解决此类问题更多地依赖于别出心裁的工程。这个过程可以通过向研究鸟类的专家征求意见有助于更好地理解猛禽的行为,以及为什么他们往往栖息在导体和交叉双臂的位置。例如,通过研究他们的生活习惯揭示了一个线索,较大的鸟的相比较小的物种更喜欢被树木所提供的盖高层建筑的巢。事实上,这更加提高了大型鸟类对电网的吸引力。 注:请通过阅读即将发刊的2015年第二季度的INMR处理架空线路大型鸟类。 Large indigenous raptors and other birdlife that perch on or nest at the top of cross-arms can become a major cause of insulator failure from the dry arc distance being bridged with branches and twigs. Finding solutions to this type of problem usually requires more ‘out of the box’ thinking than the more structured approach used in selecting the most suitable insulator design for that service environment. Since interaction with birdlife is not an insulator performance issue, solving this type of problem relies more on ingenuity than engineering. The process can start by conducting research and soliciting help from bird life specialists to better understand raptor behavior and why they tend to perch on conductors and cross-arms. For example, studying their habits reveals a propensity for larger birds to build nests on tall structures compared to smaller species that prefer the cover afforded by trees. Indeed, this is what most accounts for the attraction of large birds to the electrical grid.
