<p>A cable joint comprises an inner casing enclosing the jointed conductors of the cables being jointed, this inner casing being filled with a compound serving as electrical insulation and an outer casing enclosing the inner casing and filled with a set compound serving as a mechanical support for the jointed conductors. Thus, the compound filling the inner casing is chosen purely for its electrical properties and provides the electrical insulation of the joint and the compound filling the outer casing is chosen purely for its mechanical properties and provides the mechanical strength of the joint.</p> |
