High-temperature superconducting cables (HTS cables, supercables) are being developed for electrical power distribution. Recently, medium-voltage level cables using this technology have become available for the distribution of 20 - 200 MVA at voltage levels of 10-30 kV. It is therefore becoming increasingly urgent for distribution planners to learn of the basic properties of this new component.

This presentation will describe the basic properties of medium-voltage supercables, and their applicability in distribution grids. A specific example will be described, with a type test and pilot installation of a 13 kV, 69 MVA HTS Triax cable in the U.S.A.. The presentation will end with a few examples of longer-term perspectives for the evolution of this technology.
