5.
The grounding wire must be made of the whole cable material, the intermediate joint is strictly
prohibited, and the excess length should be cut. The skin shall be complete, and the insulation
resistance of the core wire to the ground (or metal isolation layer) shall meet the technical
requirements of the cable.
6.
The grounding wire shall be connected to the integrated grounding bar of the building. If it is
impossible to connect to the integrated grounding bar of the building, the appropriate
grounding point can be selected according to the integrated grounding situation of the indoor
building. The selection of grounding point must be higher than the grounding grid, and the
feeder grounding shall be towards the downward direction of the feeder, never upward.
7.
The grounding electrode of the self-built grounding grid for the outdoor antenna of the tunnel
must meet the design requirements. The buried depth of the grounding electrode and the
welding quality of the flat iron meet the specification requirements. In principle, the buried
depth of the grounding electrode shall not be less than 0.7 m. The non-self-built grounding
network shall be connected to the grounding network of the owner.
8.
The eNB grounding, power adapter grounding, distribution box grounding and feeder
grounding must be connected to the grounding bar independently, and the grounding bar
must have a path from the lead to the earth.
3.5 Maintenance Chamber Waterproofing
