Abstract
A power cable for transmitting electrical power includes at least two electrical conductors extending mainly along a power transmission axis. A first of the conductors called the external conductor surrounds a second of the conductors called the internal conductor along the axis. At least one insert is arranged between the internal conductor and the external conductor. The insert extends over only part of the cable along the axis. The insert introduces a first impedance between the internal conductor and the external conductor with a value different from a second impedance between the internal conductor and the external conductor outside of the part of the cable over which the insert extends.

A power cable for transmitting electrical power, comprising:
- at least two electrical conductors extending mainly along a power transmission axis, a first of the conductors called the external conductor surrounding a second of the conductors called the internal conductor along the axis,
- at least one insert comprising a ferromagnetic material, the insert being arranged between the internal conductor and the external conductor without the ferromagnetic material forming a closed loop around the internal conductor along the axis, the insert extending over only part of the cable along the axis, the insert introducing a first impedance between the internal conductor and the external conductor with a value different from a second impedance between the internal conductor and the external conductor outside of the part of the cable over which the insert extends.
