Abstract: An aerospace cable that limits the occurrence of partial discharges includes an elongate electrically conductive element surrounded by a semiconductor layer and an insulation system around the semiconductor layer. This insulation system has an electrically insulating layer surrounding the semiconductor layer. Each layer of the insulation system has a radial thickness (ei . . . ), and in that an equivalent insulation thickness (teq) of this insulation system is greater than or equal to the result of a third-degree polynomial function equation of a minimum pressure and of a maximum temperature at which the cable is intended to be used.
