1.
The installation position of the grounding bar shall meet the design requirements.
The holding pole and tower body must be connected to the lightning protection
network or grounded with a separate lead.
2.
The diameter of the grounding wire meets the design requirements. The copper
nose must be used for grounding, and the grounding resistance is required to be
less than 10 ohms. If the resistance of the public network communication equipment
placed in other systems is less than 10 ohms, the grounding network of the system
should be overlapped.
3.
The grounding wire must be the whole wire material. When laying, it should be
bound separately with other cables. All grounding wires should be fixed with wire
code or binding tape with a fixed spacing of 0.3m. The appearance should be
straight and beautiful.
4.
The copper bar must be used for the grounding bar, and the specification of the
grounding bar shall meet the design requirements. If there are no specific
requirements in the design, 300 × 40 × 4mm and fixed with expansion bolts.
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
