Abstract
A power cable has an insulated conductor; a copper water barrier, in form of a tube with a welding line, surrounding each insulated conductor; and a polymeric sheath surrounding each copper water barrier. The copper water barrier has a thickness and the polymeric sheath has a thickness such that a ratio between the thickness of the copper water barrier and the thickness of the polymeric sheath is 0.15 at most.
