Processes for manufacturing jointing assemblies for medium or high voltage electrical cables and jointing assemblies obtainable by the processes

摘要

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.

1. A process for manufacturing a jointing assembly for medium or high voltage electrical cables, the process comprising:
forming a tubular element made from a semi-conductive material; cutting out of the tubular element a first cylindrical element having a first length and a second cylindrical element having a second length; machining an end portion of the first cylindrical element to provide the end portion with an at least partially rounded profile; machining an end portion of the second cylindrical element to provide the end portion with an at least partially rounded profile; arranging the first cylindrical element at a radially inner surface of an elastomeric sleeve made from a dielectric material and extending about a longitudinal axis; arranging the second cylindrical element at a free end portion of the elastomeric sleeve, and 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.
