Lightning protection and grounding for factory buildings
Thread Content
Civil construction has begun; how should lightning protection and grounding for electrical systems be carried out? ?
It can be shared with the factory building; check the lightning protection design specifications for details
Construct in accordance with the drawings; generally, pile foundations are used as grounding electrodes, and an iron plate is welded every two spans to serve as a connection point for the circular grounding grid in the workshop
During civil engineering work, bury the lightning protection grounding grid first
For the lightning protection and grounding of newly built factories, the design must be submitted to the local lightning protection authorities for review, testing, acceptance, and certification. Without following these regulations, the newly built factory cannot be used. For electrical lightning protection grounding as well, there should be design and construction drawings along with relevant standards, so there is no need to worry about construction issues.
But now there are only electronic versions of the drawings; the blueprints have not been produced yet. What needs to be done
Connected to the plant’s grounding grid according to the drawings.
It depends on whether it’s a factory building, what the lightning protection requirements are, and what the diameter of the rebar in the ring beams is; different situations require different construction standards
Construct in accordance with the drawings; generally, grounding is carried out simultaneously with the earthwork excavation for civil engineering, as the underground components all constitute concealed works.
It belongs to civil engineering work, right? Electrical acceptance
