In the construction of foundation, the grounding body is pre-embedded. One end of the
grounding body is welded with the main grounding network of power plant while the other
end is welded with the pre-embedded channel steel in the foundation to assure firm welding
quality. The embedded grounding pole must be in accordance with the installation codes.
The maintenance entry is designed for the foundation; if needed, the working personnel can
enter into the foundation for required operation.
It is recommended to build up steps at the inlet of PCS for convenient access. The step
width and level are reasonably decided according to the on-site actual conditions.
For easy late maintenance and repair work, a proper maintenance area is constructed
around the foundation according to the on-site actual conditions. The maintenance area has
an adequate bearing capacity and levelness and conforms to the local standard/code.
Both ends of all the pre-embedded pipes are temporarily sealed to prevent impurities; other-
wise, it is inconvenient for laying cables in the late period.
Upon connection of all the electrical cables, the cable inlet and outlet and joint are sealed by
refractory mud or other appropriate materials to prevent entrance of rodents.
Please refer to the mentioned drawing and other related drawings for the rest recommended
dimensions.
Pre-bury grounding units according to relevant standards of the country/region
where the project is located.
5.3.6 Other Precautions
A drainage system should be designed on the installation site to prevent the PCS
from being immersed in water during heavy rainfalls.
Do not plant any trees near the PCS installation site to prevent the damage of PCS
by tree leaves or branches.
