Cable connection cabinet optimizing design and its economic analysis in nuclear power plant

The cross section of cables in nuclear power plant is larger than those in civil projects as its long laying route, so mismatching of cable with equipment terminal is common. Altering terminal design or increasing cable connection cabinet can solve this problem on the one hand, but increasing the construction cost and period on the other. This paper puts forward a refined method to cable type selection and length validation. This helps reduce the cost by reducing the number of cable connection cabinet. (authors)
