求翻译：在山区地区，必须谨慎考虑加装绝缘子串并联间隙，山丘地区线路如果需要安装并联间隙，则需要采用其他的防雷措施（如降低线路保护角、降低杆塔接地电阻等）提高线路防雷性能，以满足工程防雷管理目标要求。是什么意思？

In the mountain region, we must be careful to consider the installation of the insulator strings parallel gap, mountainous area of ​​line if you need to install the parallel gap, you need to use other lightning protection measures (such as reduced line protection angle, lower tower grounding resista

In mountain areas, must be carefully considered with insulated sub string clearance, and the hills line if you need to install and the clearance, you will need to use other anti-mine-measures (such as the lowering line protection, lower the rod grounding resistance, etc. ) Increase Line mine perform

In the mountainous area area, must consider the addition insulator series-parallel connection gap discretely, the massif area line if needs to install the parallel gap, then needs to use other anti-radar measures (for example to reduce line protection angle, to reduce pole lapping earth resistance a

In mountain regions, must carefully consider retrofitting of insulators and parallel gap, Hills District lines if you need to install the parallel gap, you will need to use other lightning protection measures (such as lower line protection and lower Tower grounding resistance, and so on) improving l
