摘要
A tubular covering sleeve (9) is manufactured which comprises a primary tubular body (10) externally coated with a sheath (14) formed of a layer of semiconductive material (15) coupled with an elastomer layer (16). The sheath (14) is made separately of the primary body and subsequently coupled therewith, before or after coupling of the primary body itself on a splicing region between two electric cables (2a, 2b). The sleeve one of the cables before electrically connecting the conductors (3a, 3b). Then a radial shrinkage of the sleeve (9) on the cables (2a, 2b) is caused at the splicing region. To carry out a sectionalisation (18), one end portion of the sheath and of the semiconductive layer (16) alone is turned up or mechanically removed, before or after engagement of the sheath (14) with the primary tubular body (10).
