The invention relates to a conductor () for electrical equipment, the conductor comprising at least one hollow section member () 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 () in a plane perpendicular to the longitudinal axis. The conductor may advantageously form a movable contact (blade) () of a high voltage disconnector.

Self-deicing lightweight conductor

The invention provides a support structure () comprising at least one cylindrical pillar () of vertical main axis, having a bottom end () that is connected to the ground () and a top end () connected to a component to be supported; the support structure being characterized in that the pillar () includes at least one helical slot () coaxial about the main axis of the pillar ().

Support structure comprising a shock absorbing pillar

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.

Lightweight conductor for electrical equipment and electrical equipment including at least one such conductor

An air-insulated high-voltage disconnector including a pivotally-mounted arm suitable for pivoting at one of its ends about a horizontal axis that is perpendicular to the axis &Dgr; of the arm, and also suitable for turning about its own axis &Dgr;, the free end of the arm carrying a contact part or &ldquo;hammer&rdquo; which, when the disconnector is in the closed position, co-operates with a jaw comprising a jaw support to which two facing rows of contact fingers are fixed, wherein the hammer is equipped with contact tabs co-operating with the contact fingers, each contact tab forming a wedge of angle &bgr;, which wedge acts, during disconnector closure, to meet the corresponding row of fingers with an angle of attack &agr;, said angle of attack &agr; being less than 90&deg;.

Air-insulated high-voltage disconnector

An air-insulated high-voltage disconnector includes a pivoting arm which pivots at one end about a horizontal axis perpendicular to the axis of the arm and turns about its axis. The free end of the arm carries a contact member referred to as the hammer cooperating, in the closed position of the disconnector, with a jaw including a jaw support to which are fixed two facing rows of contact fingers. The contact fingers are tubular and open at both ends.
