Reinforced submarine power cable

A submarine power cable comprising:

• a power core including a conductor, the power core having an electrical insulation system configured to electrically insulate the conductor, the electrical insulation system comprising an outer semiconducting layer, a solid insulation layer arranged radially inside the outer semiconducting layer, and an inner semiconducting layer arranged radially inside the solid insulation layer,
• wherein the conductor has a conductor joint in a joint region of the power core,
• a main armor layer including a plurality of main armor wires arranged around the power core and extending in the axial direction of the power core, and
• a joint reinforcement armor layer including a plurality of joint reinforcement armor wires axially locked relative to the main armor wires, wherein the joint reinforcement armor layer is provided only in the joint region and arranged layered with the main armor layer, the joint reinforcement armor layer and the main armor layer thereby forming a dual-layer armor only in the joint region,
• wherein the dual-layer armor is provided over and extends axially across the conductor joint,
• wherein all the main armor wires are arranged helically around the power core across the joint region with a first lay direction, and all the joint reinforcement armor wires are arranged helically around the power core with a second lay direction opposite to the first lay direction.
