Abstract
A process for manufacturing a jointing assembly for medium or high voltage electrical cables may include: forming a tubular element made from semi-conductive material; cutting out of the tubular element first and second cylindrical elements; machining an end portion of the first and second cylindrical elements to provide the end portions with an at least partially rounded profile; arranging the first cylindrical element at a radially inner surface of an elastomeric sleeve made from dielectric material; arranging the second cylindrical element at a free end portion of the elastomeric sleeve, spaced apart from the first cylindrical element, with the at least partially rounded profile end portion of the second cylindrical element facing the at least partially rounded profile end portion of the first cylindrical element; and elastically expanding the elastomeric sleeve by inserting at least one removable support element in a radially inner position with respect to the elastomeric sleeve.
