Power cable and manufacturing method thereof

A power cable comprising:

• one or more insulated conductive cores;
• a metallic screen surrounding the one or more insulated conductive cores;
• a sheath surrounding the metallic screen;
• and
• one or more dielectric optical fiber elements embedded in and surrounded by the sheath in a position that is radially outward from and spaced from the metallic screen,
• wherein each dielectric optical fiber element of the one or more dielectric optical fiber elements is helically or SZ stranded around the metallic screen, and comprises:
• a single tube surrounding a plurality of optical fibers;
• two strength members arranged side-by-side with the single tube, wherein the single tube is positioned between the two strength members;
• and
• an element jacket surrounding the single tube and the two strength members to form a flat element,
• wherein the element jacket is merged at least partially with the sheath, wherein the power cable is a High Voltage, Extra High Voltage, or Medium Voltage power cable.

A method for manufacturing a High Voltage, Extra High Voltage, or Medium Voltage power cable, the method comprising:

• surrounding at least one tube including one or more optical fibers with an element jacket to form a dielectric optical fiber element;
• forming at least one insulated conductive core;
• surrounding the at least one insulated conductive core with a metallic screen;
• helically or SZ stranding the dielectric optical fiber element around the metallic screen in a position that is radially outward and spaced from the metallic screen;
• and
• extruding a sheath surrounding the metallic screen and embedding and surrounding the dielectric optical fiber element.
