    摘要： A method of building a joint insulation of a power cable joint (3) comprising a conductor joint (7c) connecting a first conductor (7a) of a first cable length (5a) to a second conductor (7b) of second cable length (5b), the method comprising: a) winding a first electrically insulating tape (15) around an inner semiconducting layer (13) that covers the conductor joint (7c) so that the first electrically insulating tape (13) connects a first cable length insulation layer (9a) of the first cable length (5a) to a second cable length insulation layer (9b) of the second cable length (5b), to form an inner insulation layer (17) of the joint insulation, and b) winding a second electrically insulating tape (19) around the inner insulation layer (17), so that the second electrically insulating tape (19) connects the first cable length insulation layer (9a) to the second cable length insulation layer (9b), to form an outer insulation layer (21) of the joint insulation, wherein the first electrically insulating tape (15) has a higher peroxide content than the second electrically insulating tape (19), and c) crosslinking the joint insulation.
