Abstract

A high-voltage cable includes a composite core surrounded by an electrical conductor, wherein it is limited to 95° C.±5%, and the electrical conductor is made of hard aluminum with an aluminum ratio Ra of between 6 and 19, wherein Ra is calculated according to the following rule: Ra=Sc/Sa×100, where Sc is the cross-section of the composite core of the cable and Sa is the cross-section of the conductive aluminum of the cable. This makes it possible to obtain a cable with the same mass as current low-temperature cables, the same external diameter, at least the same mechanical strength and equivalent thermal expansion. This results in a cable in which the aluminum cross-section is increased by between 20% and 40% with the same mass.
