<p>For feeding electrical cables through a wall, a mounting frame is made in it, and the cables are contained in feed-through elements comprising two block halves enclosing a feed-through channel for receiving cable. The feed-through elements possibly together with filling blocks are in the mounting frame. For bringing the metal protections of the cables in the feed-through frame into electrically conductive contact with each other and the (metal) wall, a portion of the cable sheath of each cable (1) is cut away, the removed cable sheath portion is longitudinally divided into halves (6) which are inserted in excavations (4) of block halves (3), and each block half (3) at and together with cable sheath portion (6) divided into halves is wrapped with electrically conductive adhesive foil (7). After inserting cable (1), with exposed metal protection (5) in contact with foil (7), block halves (3) are put together to a complete feed-through element (2) ready for mounting. <IMAGE></p> |
