部分区域综合考虑地面合成场强及电气绝缘强度的影响确定相关距离。
Also, in Parts of districts, we consider the ground composite electrical field strength and electrical insulation strength effects together.
再根据系统确定的操作过电压倍数及电气绝缘强度（空气间隙）来确定在人不宜到达地方的交叉跨越距离；
We decide the cross and span clearance by over-voltage times and electrical insulation strength (air spacing) from the system major in places that the public not easy to arrive.
聚苯硫醚可以用来使元素在高强度，高耐温性，电气绝缘是在航空最重要的。
PPS can be used to make elements where high strength, high temperature resistance, electrical insulation are all-important in aviation.
