Abstract
A power cable joint device includes at least one tubular rigid support element, a cold-shrinkable, pre-expanded sleeve, and a releasable means for immobilizing the at least one support element with respect to the pre-expanded sleeve. Most of an exterior surface of the at least one support element is lubricated by a grease that does not flow under action of a pressure exerted by the pre-expanded sleeve. The pre-expanded sleeve grips the at least one support element over most of a length of the at least one support element. The pre-expanded sleeve also grips the at least one support element at internal ends of the at least one support element. The grease is based on a silicone or on a polyalkylene glycol and includes a filler, a pressure-withstanding additive, or both the filler and the pressure-withstanding additive.
