A method of repairing or replacing a joint for high voltage polymer cables or a high voltage polymer cable (1c), comprises the steps of: a) removing a section to be replaced of the joint or the high voltage polymer cable (1c) such that two cable ends (1a, 1b) result, whereby the two cable ends (1a, 1b) are oriented toward each other and whereby the two cable ends (1a, 1b) are positioned in a separation distance (20) from each other and whereby each cable end (1a, 1b) comprises a cable conductor (10a, 10b), b) preparing the two cable ends (1a, 1b) by exposing the cable conductors (10a, 10b) of both cable ends (1a, 1b) over a first length c) connecting the two cable conductors (10a, 10b) with a connection piece (3) which comprises two receiving sections (31a, 31b) and a centre section (30) and which is electrically conducting, whereby a length of the centre section (30d) corresponds to the separation distance (20) and whereby the cable conductors (10a, 10b) are mounted in such a way to the receiving sections (31a, 31b) that a mechanical and an electrically conducting connection is established.
A connection piece for connecting two cable conductors of high voltage polymer cables in a method of repairing or replacing a joint of a high voltage polymer cable, the connection piece comprising two receiving sections and a centre section, the two receiving sections being releasably connected to the centre section by means of a threaded connection allowing to establish a mechanical and electrically conducting connection between each of the receiving sections and the centre section-, each of the receiving sections having a bore for receiving an end of one of the two cable conductors therein, the centre section being in the form of a full cylinder with a length which is greater or equal to 10 cm and which corresponds to a separation distance between the two cable ends to be connected, wherein the handedness of the threads of the two receiving sections is different from each other and wherein the centre section comprises at least one central piece comprising two threads of different handedness.
