Abstract
The invention encompasses an electric cable which is made up of a metallic shield, a semiconducting polymer sheath surrounding a cable conductor and a moistureproofing layer in the form of a semiconducting hydrophobic gel. This construction assures an effective moisture barrier between the metallic shield and the semiconducting polymer layer by providing a semiconducting gel fully compatible with both.
