<p>A cable transit for protecting against the ingress of, e.g., liquids and electromagnetic disturbances at a transit location in a wall includes a sleeve (10) and a nut means (11) for fitting the transit tightly in the wall. The transit also includes a cable seal (14) which comprises two semi-cyclindrical bodies (143, 144) made of a compressible material and together fitting in the sleeve (10). The semi-cylindrical bodies have an adaptable centre hole (140) for accommodating a cable to be passed through the wall, and are comprised of several peelable layers. The semi-cylindrical bodies can be pressed together in tight abutment with the sleeve (10) and with the cable, by means of the nut means (11). The standard earthed cable sheet is earthed by means of a conductive screen. At least one peelable layer is removed along a part of the semi-cylindrical bodies (143, 144), so that the semi-cylindrical bodies will present at this location a centre hole (140) whose diameter is greater than the diameter along the remaining part of the semi-cylindrical bodies. Each semi-cylindrical body is covered with a conductive part-screen (141) along said remaining part.</p> |
