A large number of magnets in the LHC will be powered through flexible superconducting cables, located in a tube attached to the cold masses, the so called Line N. Finding a viable compromise between flexibility and the prevention of conductor movement and a thorough understanding of the quench behaviour were the two main challenges for the design of suitable cables. Measurements on prototypes of various 600 A and 6 kA cables as well as detailed computer simulations determined the design parameters. This talk will describe key properties of the cables of line N and the path which led to the final designs. Manufacturing of the cables will start this year in order to be ready for installation between 2003 and 2006.
