Seeking help with cable selection
Thread Content
It’s a 10,000-volt high-voltage cable with an aluminum core; the load consists of two 630-transformers, and the distance between them is approximately 2,200 meters. Should I choose a 150-model or a 120-model? 120 is clearly a bit small; the boss still needs one of size 95. It’s better to go with a larger size, so I think I’ll choose 150. I’m very conflicted. Give some advice.
Reference can be made to Chapter 9 of the \"Manual for Industrial and Civil Power Distribution Design (3rd Edition)\"
The 95 aluminum core is definitely there； The single-core version can carry a current of 290A, while the three-core version can carry 235A (with armored shielding) ； Three-core, 230A current carrying (armored)
Theoretically, that’s the case, but in practice no one dares to use it that way – over 2,000 meters! Have they taken pressure drop into account? It’s better to be cautious.
Has the voltage drop been calculated? 95 is sufficient
