A METHOD OF CONNECTING A MINERAL-INSULATED ELECTRIC CABLE,IN PARTICULAR IN THE REACTOR BUILDING OF A NUCLEAR BOILER

摘要

Since the mineral insulation (M) of the cable (C) is sensitive to moisture from which it is protected over the length of the cable by a sheath (G), the bared front length (8) of the cable core (A) is initially connected to a connection length (14) whose insulation (22) is constituted by an organic material which is insensitive to moisture. The prior connection zone is embedded in a block of resin (24) surrounded with its own sheath (26). The desired electrical connection is made to the other end (18) of said connection length inside a non-sealed box. The invention is applicable to transmitting signals even in the event of an accident to a nuclear reactor.
