A high-voltage device has an inner conductor and an insulating member that surrounds the inner conductor along the longitudinal direction thereof. In order to increase the reliability of the high-voltage device, at least one optical waveguide rests against the inner conductor in at least some sections, extends out of the insulating member and can be connected to an evaluation unit for recording measured temperature values. Furthermore a method measures a temperature of the inner conductor of the high-voltage device.

A protective apparatus for a distribution line conductor includes an elongate tube configured to be installed on the conductor and a plurality of annular members concentrically positioned on the tube and configured to rotate independently of each other. The tube has a longitudinal axis and defines a longitudinally extending chamber configured to receive the conductor. The tube has opposite first and second ends and a longitudinally extending opening from the first end to the second end that facilitates installation of the elongate tube on the conductor. Each annular member includes an outer surface and a plurality of circumferentially-spaced apart members extending outwardly from the outer surface. Each annular member includes a longitudinally extending slot that is configured to align with the longitudinally extending opening of the tube to facilitate installation of the elongate tube and the plurality of annular members as an assembly on the conductor.

An electrical component cover includes a central portion, a first end portion and a second end portion and one or more flexible portions between the central portion and the first end portion or second end portion to enable the electrical component cover to flex and thereby facilitate varying geometries in power lines attached to insulators.

The invention relates to a contamination protection device (10) for high-voltage insulators (3), and to an assembly of a contamination protection device (10) and a high-voltage insulator (10). The contamination protection device (10) is designed for fastening to the insulator cap (5) of the high-voltage insulator (3) and has a protective shield (11), which extends radially around a feed-through opening (12) for the connection element (7) of the insulator cap (5), the feed-through opening (12) being surrounded, on the one side of the protective shield (11), by a fastening region (23) for interlocking connection to the insulator cap (5). On the other side of the protective shield (11), two eyes (14) for the insertion of a tab element (30) are provided and a tab element (30) is provided. The eyes (14) are arranged in such a way that the tab element (30) extends over the feed-through opening (12) after having been inserted

An apparatus for protecting a component of a power distribution system against wildlife, the apparatus comprising a cover having a first wall and a second wall, the first wall and the second wall being spaced apart to receive part of the component; the first wall having an opening for receiving a pin; and a cantilever mount at the opening for supporting the pin in the first wall. Various configurations of cantilever mount and pin may be used. Opposing pins in opposing walls may be used. The pins may extend towards each other and may or may not meet.

Shatter protection for a high voltage apparatus with a ceramic insulator includes at least one electrically insulating tube including a plurality of holes going through an envelope surface. The electrically insulating tube has a diameter such that there is a minimum distance between the tube and the ceramic insulator when arranged concentrically. A method for producing a shatter protection includes winding a first helix shape of the electrically insulating fiber composite material at a first pitch such that there is a first gap between the winding turns, and winding a second helix shape of the electrically insulating fiber composite material onto the first helix shape in the opposite direction and at a second pitch, such that there is a second gap between the winding turns. Thereby forming a first electrically insulating tube with holes formed by the first and second gap between the winding turns.

A veneer for a wall-mounted keypad may include indicia that are laser cut therethrough and that are representative of functions that may be performed by the keypad. The veneer may include a recess that extends into an inner surface of the veneer, proximate to the indicia. The recess may be shaped such that a perceived aesthetic of an outer surface of the veneer is preserved during formation of the indicia. The recess may for example have an organic shape defined by a curved outer perimeter that does not define any corners.
