SEALING DEVICE FOR SEALING A MINERAL-INSULATED CABLE, MINERAL-INSULATED CABLE AND METHOD FOR SEALING THE CABLE

摘要

The invention is concerned with a sealing device (16) for sealing a space (14) between an outer sheath (11) or a support tube (31) of a mineral-insulated electric cable (10) and at least one wire (12) arranged inside the outer sheath (11). The sealing device (16) comprises a sealing plate (17) made of or containing an electrically isolating material, wherein the sealing plate (17) comprises at least one through-hole (18), each for passing through one wire (12) of the cable (10). The invention is characterized in that a ring element (19) is arranged at a respective edge (20) of each through-hole (18), wherein each ring element (19) is made of a metal or an alloy and provides an inner contact surface (21) for generating a positive substance jointing between the ring element (19) and the wire of the cable (10).
