An isolator for an aircraft fuel tank configured to separate an electrically conductive internal panel of the fuel tank from an electrically conductive pipe that passes through the panel. The isolator includes: a plurality of first attachment points for attaching the isolator to the panel, a plurality of second attachment points for attaching the isolator to the pipe, and an aperture defined by an outer wall and extending from a first side of the isolator to a second side of the isolator. The aperture is configured to receive the pipe in use, wherein the isolator is formed of a non-electrically conductive material.

This invention relates to a seal system for sealing between an elongate element such as a cable and a surface or substrate around an aperture in the surface through which the elongate element passes. The seal system comprises a seal body to surround the aperture and seal against the surface or substrate around the aperture. The seal body comprises at least one passage for penetration of the elongate element through the seal body at a side of the seal body. The at least one passage providing for a seal to the elongate element. Also provided is a fixing component adapted to be attached over at least part of the seal body and/or through the seal body to seal with the surface or substrate.

The present invention concerns a wedge for a lead-through system. The wedge comprises a first wedge element, a second wedge element, a third wedge element and a fourth wedge element. The first and second wedge elements are arranged moveable towards and away from each other. The third and fourth wedge elements are placed on opposite sides of the first and second wedge elements, abutting the first and second wedge elements along sloping surfaces. The wedge elements and the sloping surfaces are so arranged that the third and fourth wedge elements will be moved away from each other when the first and second wedge elements are moved toward each other and that the third and fourth wedge elements are moved toward each other when the first and second wedge elements are moved away from each other. The wedge further comprises a bracket on the outside of the first wedge element. The bracket receives a socket arranged to be able to rotate in relation to the bracket. A compression screw is connected with one end to the second wedge element and goes through an opening of the first wedge element. A head of the compression screw is received inside the socket of the bracket.

The present invention concerns a module (1) of a seal or transition for cables or wires, which module (1) is to be placed inside a frame (10) together with one or more compression units (12). The module (1) comprises two module halves (2). Each module half comprises an outer part (3, 17, 19, 21, 23, 25, 27, 30, 33). The outer part has a straight section (3′) and two end sections (3″) at the ends of the straight section and placed perpendicular to the straight section, giving a U-form in end view. An inner part (5, 18, 20, 22, 24, 26, 28, 31, 34) is placed in a recess (4) formed between the end sections of the outer part (3, 17, 19, 21, 23, 25, 27, 30, 33). The inner part (5, 18, 20, 22, 24, 26, 28, 31, 34) has a number of layers (6).
