Abstract: The invention relates to a conductor (2) for electrical equipment, the conductor comprising at least one hollow section member (2) of electrically conductive material that is elongate along a longitudinal axis (Y), the conductor having an outside surface in which at least a portion forms corrugations (23, 24) in a plane perpendicular to the longitudinal axis. The conductor may advantageously form a movable contact (blade) (2) of a high voltage disconnector.

Abstract: The invention relates to a conductor for electrical equipment, including at least two electrically-conductive material support elements spaced apart from each other along a longitudinal axis (Y) and at least four electrically-conductive material structural sections elongate along the longitudinal axis (Y), curved transversely to the longitudinal axis, and supported by the support elements; wherein the support elements further hold apart in pairs the at least four curved structural sections, the separation maintained between two curved structural sections of a pair defining an open area extending transversely to the longitudinal axis and at least between the support elements, said open area reducing in size progressively and continuously. This conductor may advantageously form a movable contact (blade) of a high-voltage disconnector.

Abstract: A method and an apparatus to obtain a surface mapping of a ballistic piece of evidence (BPOE) under examination, such as a bullet or a spent cartridge case, that can be used thereafter as a 3D signature for identifying purpose during ballistic test comparison. The method comprises providing a measurement unit adapted to acquire a relief map of the surface of the BPOE and acquiring with the measurement unit the relief map of the surface to thereby obtain the mapping of the surface of the BPOE. Preferably, the measurement unit of the present invention comprises a confocal sensor such as confocal microscope. Also, the present invention includes acquiring the relief map of the bullet surface or of the cartridge case surface by acquiring and assembling a mosaic of regional reliefs that are partly overlapping with their surroundings regional reliefs.
