ABSTRACT:
A tubular covering sleeve for joints of electric cables may include a primary tubular body and a coating sheath. The primary tubular body may include at least one annular insert of semiconductive material integrated into at least one layer of insulating material. The coating sheath may include one or more layers of semiconductive material mechanically engaged in a condition of resilient radial expansion around the primary tubular body so as to exert a centripetal tightening action on the primary tubular body. A junction for electric cables may include devices for mutual connection between the conductors of the cables and a covering sleeve applied around the devices for mutual connection and around the cables. Each cable may include at least one conductor disposed in an insulating coating and a shielding coating externally applied to the insulating coating.
