Cable branching structure
An electric wire branching structure (1) branches a shielded electric wire (30) with a plurality of electric wires (10) from a main wire (30A) to a plurality of branch wires (30B, 30C). The electric wire branching structure (1) includes an electroconductive shield member (100) configured to cover the electric wires (10) corresponding to the main wire (30A) and the branch wires (30B, 30C). The shield member (100) has a plurality of electric wire insertion openings (111, 112) for the electric wires (10) corresponding to the branch wires (30B, 30C) to be inserted for each of the branch wires (30B, 30C).
Triaxial mineral insulated cable in flame sensing applications
An apparatus and method for flame sensing within a turbine. A sensor assembly, an electrical assembly and a cable assembly extending therebetween. A photodiode generates an electrical signal and the electrical assembly determines a characteristic. An inner conductor electrically connects the photodiode to the electrical assembly. A first insulating layer, with mineral insulation material, surrounds the inner conductor. An inner sheath, with electrically conductive material, surrounds the first insulating layer. A second insulating layer, with mineral insulation material, surrounds the inner sheath. An outer sheath, with an electrically conductive, metal material, surrounds the second insulating layer. The cable assembly is configured for use up to about 300 degrees Celsius or greater. The portions of the cable are constructed and configured, and connected between the sensor assembly and the electrical assembly, to enclose the inner conductor such that the inner conductor is not exposed outside of confines of the cable.
High-pressure feedthrough for feeding through a coaxial cable into a high-pressure zone
The present disclosure relates to a high-pressure feedthrough for feeding through a coaxial cable from a low-pressure zone into a high-pressure zone, wherein the high-pressure feedthrough has a support structure having at least one elongate bore that extends from a low-pressure side of the support structure up to a high-pressure side of the support structure; wherein the elongate bore is suitable for receiving at least the inner conductor of a coaxial cable that can be continuously fed through the elongate bore from the low-pressure side to the high-pressure side; and wherein the high-pressure feedthrough has one or more components that serve in the axial direction of the elongate bore as an outer conductor and/or dielectric of the inner conductor of the coaxial cable fed through the elongate bore.
Cable fitting for connecting a high-voltage cable to a high-voltage component
A high-voltage cable fitting, typically a cable end termination or a cable joint, includes coaxially arranged around an axis a rigid conical insulator, an electrically insulating, elastomeric stress-relief cone matching the rigid conical insulator through a conical interface and an axially aligned current path. The current path connects a conductor of the cable to a high-voltage current terminal arranged on top of the rigid conical insulator and provided for connection to a high-voltage component. The rigid conical insulator is configured as a condenser core and includes a plurality of electrically conductive field-grading layers, which are arranged concentrically around the axis, and a rigid polymeric matrix which embeds the field-grading layers. In order to keep the size of the cable fitting small and to enable the fitting to carry high rated continuous currents a section of the cable conductor, which is stripped off the insulation of the cable, extends from the conical interface to the high-voltage current terminal and forms the axially aligned current path, and the condenser core comprises an axially aligned tubular duct which receives the stripped-off section of the cable conductor and which passes two opposing front faces of the condenser core.

CUTTING FIXTURE EXHIBITING RAM ACTUATED AND MULTIPLYING LEVER FORCE FOR REMOVING SUCH AS AN H-TAP CRIMP FROM A UTILITY POWER LINE
A cutting fixture for incising a tap portion installed between a pair power cables. A fixture body is mounted atop a power press tool in contact with a linearly advancing ram of the tool. The fixture body terminates in a downwardly facing support surface. A pair of levers are pivotally mounted to the fixture body, each including a bottom end profile and a roller at an upper end which, in response to upward displacement of the ram, multi-directionally advances to displace against an underside of a linearly movable carriage supported upon the fixture body in proximity to the levers. A cutting blade is supported upon the carriage and, in response to elevation of the carriage, displaces upwardly in a force multiplying fashion to section the H-tap positioned between the carriage and the downwardly facing support surface in order to permit its removal while preserving the integrity of the cables.
