  • Patent number: 12573526
    Abstract: A power cable includes from inside to outside: a conductor; an insulation system having an inner semiconducting layer, an insulation layer, and an outer semiconducting layer; a metallic water blocking layer including a first axial section, a second axial section, and an intermediate axial section arranged between the first axial section and the second axial section and made of a lead-free metal material which is different from a first metal material of at least one of the first axial section and the second axial section. The intermediate axial section is joined thermally along its entire inner or outer perimeter with each of the first axial section and the second axial section to obtain watertight connections. The lead-free metal material has a lower yield strength than the first metal material.
