Abstract
A power cable for use in high moisture and chemically corrosive environments has a longitudinally-folded sheath for encapsulating one or more electrical conductors. A plurality of overlapping folds at the longitudinal edges of the sheathing material creates a labyrinth-type sealing joint for maintaining moisture and gas integrity of the cable. A sealant is provided within the circumferential and radial spaces defined by the overlapping folds of the joint.
