Abstract
A cable joint includes at least two cables each having inner conducting elements. At least one of the cables has a layer of paper insulation impregnated with an oil. The inner conducting elements of the cables are secured to each other at a junction. A sealing tape has an inner layer and an outer layer. The sealing tape is wrapped about the junction such that the inner layer is in contact with the cables. The inner layer is provided with a deformable oil barrier including a sealing mastic that is resistant to chemical attack from the oil and resistant to migration of the oil there through. The outer layer carries the inner layer. The outer layer is provided with a substantially rigid tape that is resistant to deformation and expansion of the inner layer that forms a protective sleeve about the inner layer.
