AmpaCity serves as a lighthouse project because it is the first time a 1-km (0.62-mile) HTS cable system was installed with an HTS fault current limiter in a distribution network within a city center.

400.5]. Where the number of current-carrying conductors in a cable or raceway exceeds three, the allowable ampacity of each conductor must be adjusted in accordance with the following multipliers: If ...

A. Where more than two NM cables are installed in contact with thermal insulation without maintaining spacing between cables, the allowable ampacity of each conductor must be adjusted in accordance ...

A High Temperature Superconducting (HTS) power cable is a wire-based device that carries large amounts of electrical current. There are two types ... providing even greater ampacity, further reducing ...

This project, called the AmpaCity Project(Opens in a new window), is focused mostly on possible advantages for city infrastructure -- notably, that a cable with almost-zero transmission losses can ...
