ABSTRACT:
Sealed power cables (e.g. for underground or submarine use) are often equipped with a metal sheath. A problem with some such cables is that their insulation is subject to greater thermal expansion of the cable during use than the metal sheath is capable of following. According to the present invention the metal sheath (5) is longitudinally corrugated either when the metal sheath is manufactured or by pressing a metal sheet which is originally plane over resilient ribs disposed longitudinally on the cable.
