1. Outdoor rooms shall have a single grounding ring made of solid copper, with minimum dimensions of 50mm × 6mm; this ring shall be mounted on the wall. A continuous grounding ring shall also be installed in the floor of cavities or basements. 2. The armoring of outdoor cables shall be connected to the grounding ring through gland plates and metal cable glands in the substation
I’m sorry, just trying to encourage you.
This post was last edited by zhouzurui on 2015-9-21 09:15. My opinions may not be accurate; they are provided for reference only. I’d like to correct one thing: there are words in the text that aren’t separated properly. 1. In the auxiliary rooms located on the site, a solid copper grounding ring with minimum dimensions of 50mm ×6mm should be installed on the wall; a continuous grounding ring should be installed in the floor of the basement or foundation. 2. The cable armouring of outdoor cables shall be connected to the ground ring through a gland plate and metal cable glands in the substation. In the substation, the sheath of outdoor cables should be isolated from the grounding ring using metal cable connectors and terminal plates. I’m not a professional; some terms should have their proper technical names. For example, “gland plate” and “metal cable glands” were translated by me as “connector plate” and “metal cable connectors” respectively.
1. In the rooms associated with this area, there is a solid copper grounding ring of minimum size, 50 mm×6 mm, installed on the wall; continuous grounding rings should be installed on the floor of the basement or underground area. 2. The steel reinforcement of outdoor cables should be connected to the grounding rings, as well as the metal clamps used for cables in the substation
Sir, could you give me your QQ number? By the way, I have another question: Individual earth grids within a distance of 30m should be interconnected using at least two conductors, each with a minimum cross-sectional area of 70 square millimeters. How should it be translated
Thank you! Thank you! Let me ask again how to translate this sentence. Individual earth grids within a distance of 30m shall be interconnected using at least two conductors, each with a minimum cross-sectional area of 70 sq mm
Within a distance of 30 meters on the individual Earth grid, Inter Milan and each of the at least two conductors should have a minimum cross-sectional area of 70 square millimeters
The electrode depth should not exceed 15M, and the distance between the driven earth electrodes should be at least equal to the depth of those electrodes. :last sentence of handshake
A 30m grounding grid should have at least two conductors with cross-sectional areas of not less than 70 square millimeters that intersect with each other
:handshake:handshake:handshake, expert!
I’m also in charge of quality control. Senior, please take a look at this sentence: The electrode depth should not be greater than 15M, and the distance between the driven earth electrodes shall be at least equal to the depth of those electrodes. Let’s leave a QQ number by the way
