Underground Distribution Design
(OP)
Good day, I would like to ask what size and type of underground cable can I use if the voltage is 7,62kV and the total current 345 A. Kindly help me how to apply the derating factors in determing the size of underground cables. Which is better, directly buried or cables in ducts; XLPE or EPR; 3 single core or multicore? Thanks a lot.

There is no 'best' answer for most, as already stated.
Start with local Codes and Standards.
Then ask your local POCO if they have their own standards and practices.
Doing things in a way similar to your neighbors is often a good idea.
