A cable feedthrough for a control cabinet having a casing that can be closed with a casing cover. The cable feedthrough includes a frame which is open on one side and can be fastened detachably to and flush with an end face of the casing. At least one removable feed element for feeding through a cable is situated in the frame.

A high voltage connection between a first line of a traveling wave tube and a second line of a voltage supply unit for the traveling wave tube includes a plug which is connected to an end section of the first line or of the second line by a crimp connection, and a socket which is connected to an end section of the other line by a crimp connection. Furthermore, a method for manufacturing a high voltage connection is also described.

A bushing for a transformer is provided, the bushing comprising an elongate enclosure body to accommodate a conductor extending along a longitudinal axis, the conductor having a first terminal end a second terminal end, the ends extending from opposite sides of the enclosure body; and a mounting flange fitted to the enclosure body to enable the bushing to be mounted to an enclosure of the transformer. The enclosure body comprises two electrically insulating layers partially surrounding the conductor, a first layer of the insulating layers being substantially provided by a first polymeric material and a second layer of the insulating layers being substantially provided by a second polymeric material, the layers being arranged about the conductor in such a manner that the bushing is substantially cavity-free. In an embodiment, the first layer defines an inner core, with the second layer providing an outer cover which at least partially covers the inner core.

The invention relates to a cable contact weather protection device for receiving cable contact points, in particular of fiber optic cable contact points, with at least one cable pass-through sealing unit comprising at least two separate sealing modules, which are exchangeable independently from each other and each of which is provided to at least sectionally completely encompass, in at least one usage state, at least one elongate body in a circumferential direction.

An air conditioning flashing hood adapted to be connected to the wall structure and extend through the exterior wall of the structure to provide a passage through which a refrigerant line and an electrical control line may extend to communicate with an external compressor. The air conditioning flashing hood includes an internal sealing element which compresses against the outer surface of the refrigerant line and the electrical control line to form a substantially weather-tight seal therebetween to mitigate fluid migration along the lines into the structure, as well as to provide a barrier for any bugs, debris or animals to keep such undesirable objects from entering the structure.

A dry-type cable wire outlet device for a submersible electrical pump includes a wire outlet box positioned in a wellbore, a cable protection pipe, a wire outlet sealing device and a cable. The wire outlet box is connected to the top of a submersible electrical pump. One end of the cable protection pipe is connected to the top of the wire outlet box, and the other end extends out of the well cover of the wellbore. The cable is positioned in the cable protect pipe and connected with the submersible electrical pump through the wire outlet box. The wire outlet sealing device is connected to the well cover, and an end of the cable protection pipe extending outside the well cover is positioned in the wire outlet sealing device. When the device is in use, the opening at the top end of the cable protection pipe is no longer exposed.

A connection apparatus 10 for mounting a cable to a structure such as a wind turbine or oil rig. The apparatus 10 including a receiving member 14 having a hollow body with a diverging mouth, a latch member 22 movably mounted on the outside of the receiving member 14 with a latch part 24 extending into the receiving member 14. A mounting member 16 is provided which mounts the cable extending therethrough. The mounting member 16 is selectively locatable in the receiving member 14 with the latch part 24 engaging with a retaining formation in the form of a groove 56 to retain the mounting member 16 in the receiving member 14 and hence retain the cable mounted to the structure.
