摘要
做好引外金属水管、通信线路和电源等的隔离措施，在靠近围墙的220kV设备场地区域采取加密水平地网网格的措施，在靠近围墙的设备区域地面铺设高阻砾石或高阻层。
Quarantine measures in metal pipeline, communication line and power supply are recommended. Horizontal grounding grid refinement is adopted to 220kV facilities site areas beside the wall, and high - resistance boulders or layers are laid also. High - resistance layer （to about 2 meters） is plated to the framework or shell of the facilities. Make it farther from the site near master control building.
