For the lightning protection and grounding design of the reconstruction and expansion of mobile communication base stations, the lightning protection and grounding technology transformation of existing base stations can also be implemented as a reference. The lightning protection and grounding design of mobile communication base stations located in comprehensive communication buildings should be implemented in accordance with YDJ26-89 \"Interim Technical Regulations for Grounding Design of Communication Bureaus (Stations)\" and this specification. For communication base stations that use commercial buildings (residential houses, commercial office buildings, etc.) as computer rooms, this specification should also be followed. The ground network should be laid out according to the possible environmental conditions on site, but the working ground, protective ground, and building lightning protection ground of the computer room should share the same ground network.
