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.

A bulkhead passthrough connector containing a printed circuit board (PCB) for transferring electrical signals across a bulkhead to an electronic valve actuator, an electronic valve actuator configured to operate and communicate with a valve using a PCB through a bulkhead, the electronic valve actuator, and a method of assembling a bulkhead passthrough connector incorporating a PCB. The embodiments may include a passthrough partition which separates one side of the bulkhead from another. A PCB retainer may also be secured to the passthrough partition. The PCB is attached to the PCB retainer and extends from one side to another side of the bulkhead through the passthrough partition. The PCB further includes electrical paths printed on the PCB and electrical connectors located on both sides of the bulkhead to enable communication with external devices.

Disclosed is a user guidance system (2) for cable, pipe or wire transits (1; 1a . . . 1n; 400) of a type which has one or more transit elements (10, 20, 30, 40; 42: 400) to form a sealed installation of one or more cables (7), pipes or wires. The user guidance system (2) comprises a communication network (60; 60a-c; 61, 61a-n, 62), and a computer resource (70) which is connectable to the communication network. The user guidance system (2) also comprises a plurality of transit indicator devices (50; 50a-50n; 250; 350; 450), each being connectable to the communication network (60; 60a-c; 61, 61a-n, 62) and each being located at or within a respective transit (1a-1n). The computer resource (70) is configured to receive a command (74) from an authorized user (4), and in response send a remote instruction (76) to one or more of the plurality of transit indicator devices (50; 50a-50n; 250; 350; 450) over the communication network (60; 60a-c; 61, 61a-n, 62). This causes the receiving one or more transit indicator devices (50; 50a-50n; 250; 350; 450) to provide a visual indication for guiding a local user (3) at the respective transit(s) (1a-1n) where the one or more transit indicator devices (50; 50a-50n; 250; 350; 450) is/are located.
