Abstract
The present disclosure relates to a submarine cable in which cross-wound directions and cross-wound pitches of a metal wire and a shielding member surrounding an outer side of the metal wire that constitute a metal shielding layer of the submarine cable are optimized to minimize damage to the metal shielding layer, to enable rapid energization in the event of an accidental current, and further to enhance flexibility by varying the cross-wound pitch of at least one of the metal wire and the shielding member that constitute the metal shielding layer according to an environment in which the submarine cable is laid.
Claims10
A submarine cable comprising:
- one or more power units,
- wherein each of the one or more power units comprises:
- a conductor;
- an internal semi-conductive layer surrounding the conductor;
- an insulating layer surrounding the internal semi-conductive layer;
- an outer semi-conductive layer surrounding an outer side of the insulating layer;
- and
- a metal shielding layer provided on an outer side of the outer semi-conductive layer,
- wherein the metal shielding layer includes a plurality of metal wires spaced apart from and spirally cross-wound on the outer side of the outer semi-conductive layer, and a shielding member cross-wound on an outer side of the plurality of metal wires, and
- wherein the plurality of metal wires and the shielding member are cross-wound in the same spiral direction, and a cross-wound pitch of the shielding member is smaller than a cross-wound pitch of the plurality of metal wires and greater than a cross-wound width of the shielding member.
