Abstract: The reasonably selection of power cable section could raise the security of power distribution system and reduce accidents potential. Combining with AP1000 nuclear power engineering practice, introduction was made to the principle and effective way of power cable section selection of AP1000 nuclear power plant from the corner of power cable carrying capacity, anti-short-circuit capacity, voltage loss, economy of investment and operation, and so on. After the analysis and calculation of carrying capacity, laying environment and voltage drop etc factors, this paper obtained power cable section option lists of different load types for different laying environment, which provides references for the power cable sizing design in other nuclear power plant.
Key words: nuclear power plant; power cable; section; cable laying
