Abstract
A cable fitting for the protection of cable connections in a medium voltage range has a shrinkable inner insulating sleeve with a field controlling or shielding element as a coating on an inner surface, a shrinkable outer protective sleeve and a protective sleeve that completely covers the arrangement. A combination of the field controlling or shielding element with the shrinkable inner insulating sleeve reduces the number of steps in forming the cable fitting on the cable connection.

A cable fitting for the protection of a cable connection in a medium voltage technology, wherein stripped cable conductors are connected to a conductive connecting element, a field shielding element covers the set off edges of the cable conductive layer, a shrinkable inner insulation sleeve, a shrinkable outer insulation sleeve, a conductive layer and a shrinkable protective sleeve that completely covers the arrangement are arranged lying on top of one another from inside to outside over the joint, the improvements comprising the field shielding element being arranged as a coating on the inside surface of a shrinkable inner insulation sleeve and the field shielding elements being deformable at least during the step of installation.
A method of forming a cable fitting between the ends of stripped cable conductors comprising the steps of assembling a first shrinkable sleeve having a field shielding element arranged on an inner surface thereof, and an additional shrinkable sleeve on one of the two cable conductors, joining said conductors together with a connection element, then slipping the first shrinkable sleeve onto the joined-together conductors, heating to shrink said sleeve with field shielding element onto the joint, then slipping the additional shrinkable sleeve onto the first-mentioned sleeve and heating to shrink it onto said first-mentioned sleeve.
