System for providing a conduit sealingly to a through-opening in a plate-shaped construction element so that at least one pipe and/or cable can extend through the conduit and so that after sealing remaining space in the conduit a completely sealed-off pipe and/or cable penetration through the plate-shaped construction element is obtained, wherein the system is such that it is mechanically mountable, wherein the system is further such that it is mountable from only one side of the plate-shaped construction element, by only one worker.

A penetration fitting assembly includes a pipe gasket having an annular portion defining a central opening and first and second stem portions extending in opposite directions from the annular portion, an inner ring assembly configured to surround the pipe gasket and including first and second inner ring halves, a ring gasket assembly configured to surround the inner ring assembly and including first and second ring gasket halves, a wall gasket, an outer ring assembly configured to surround the ring gasket assembly and including first and second outer ring halves, and a clamp configured to surround the outer ring assembly. When the penetration fitting assembly is installed, the outer ring assembly compresses the wall gasket against the wall of the sump, the clamp compresses the ring gasket assembly between the inner ring assembly and the outer ring assembly, and the clamp compresses the pipe gasket against the pipe or conduit.

A wedge clip (13) to be used to control the compression of a compression unit. The compression unit is part of a transition for cable or pipes. The transition further comprises a frame (1) and modules (3) placed inside the frame (1), whereby also the compression unit is placed inside the frame (1). The compression force is increased by turning two screws (5) of the compression unit outwardly and a distance between heads of the two screws (5). The compression unit as such is an indication of the applied compression force. The wedge clip (13) is adapted for use on said compression unit. The wedge clip (13) is formed of an elongated plate (14) bent over itself.

A transport element support assembly comprises a front plate, a back plate, and a grommet. The front plate has a first opening and a first set of holes. The back plate has a second opening and a second set of holes. A chamber is formed by the first opening and the second opening and is configured to hold a transport element. The grommet is positioned within the chamber. The transport element support assembly formed by the front plate, the back plate, and the grommet is configured to provide electrical isolation between the transport element and an aircraft structure.

A heat exchange pipe joint includes a first pipe and a second pipe that are separately formed and in communication with each other. The first pipe is detachably connected to a second side of the installation plate, and the second pipe is detachably connected to a first side of the installation plate. When the heat exchange pipe joint is applied to the battery pack, the heat exchange pipe joint in a split-structure requires a small operation space for detachment and installation. In this case, a process of taking out the entire heat exchange pipe joint from the case can be avoided. In this way, the detachment and installation of the heat exchange pipe joint can be easy and convenient, thereby facilitating the reparation process thereof.
