How to calculate the current-carrying capacity of 10KV high-voltage cables? For example, 3X185 square mm and 1X185 square mm
The current-carrying capacity of a cable has nothing to do with voltage. It’s the same algorithm. The difference isn’t significant. Medium-voltage cables generally do not require verification of their current-carrying capacity (in fact, this is because their capacities are already high), as the requirements for thermal stability checks are very stringent!
1# fgcwzfyj: For copper materials, it is over 500 amperes, while for aluminum materials, it is over 400 amperes
3# nmgbjh: The calculations are clearly explained in Ma Guodong’s book \"Current Carrying Capacity of Wires and Cables\" published by the Shanghai Cable Research Institute
