光缆网建设中的防雷接地方案

Lightning Protection and Grounding Scheme in Optical Cable Network Construction

分析了光缆网建设中防雷接地必要性,指出防雷接地的常见错误做法,分别给出直埋光缆、电杆及吊线的接地要求和方法,明确了吊线、避雷线的接地电阻要求,较为详细地描述了光缆配线架、光缆交接箱、终端盒等终端设施的接地要求,分场景给出分纤箱接地方案,对自建接地体的材料、施工工艺等均提出明确要求。

It analyzes the necessity of lightning protection and grounding in the construction of optical cable networks,and points out the common wrong ways.And then the grounding requirements and methods of buried optical cable,pole and suspension line are given respectively.The grounding resistance requirements of suspension line and lightning conductors are defined,and the grounding requirements of terminal facilities such as cable distribution frame,optical cable box and terminal box is described in detail.At the same time,the material and construction technology of self-built grounding body are clearly demanded.
