Abstract: In allusion to the problem that in Haiyang nuclear power project site the power cable with big section can not terminate in motor junction box, this paper introduced the different computational process of power cable selection between American standard and national standard and compared the differences between the standards. The cause producing the terminating problem was carried out analysis. This paper proposed to change the junction box to increase the transfer box etc measures to solve the terminating problem.
Key words: cable terminal; cable section; voltage drop check; data exchange
