Abstract

In an inexpensive and simple method of effecting a joint between two overhead electric conductors incorporating optical fibres or between an overhead electric conductor incorporating an optical fibre and an optical cable extending to a sub-station or other location, at least a part of each or the overhead conductor is introduced into a metal sleeve extending from a wall of a metal housing and the sleeve is compression jointed to the conductor to effect a mechanical and electrical joint between the conductor and the housing. The part of the conductor protruding into the housing is cut back and a joint is effected between the optical fibres of the two overhead conductors or between the optical fibres of the overhead conductor and the optical cable that has been introduced into the housing. The housing is sealed to render it fluid tight and is preferably filled with petroleum jelly. An elongate metal shroud may be assembled around the metal housing and be so shaped as to provide aerodynamic and corona protection.
