Abstract: The application concerns a compression sealing gasket including an annular main body made of an elastomer material and having a main axis A, the main body including an annular radially outer face and an annular radially inner face parallel and coaxial to each other, wherein the gasket includes an insert mounted on the inner face. The application also concerns a sealing system having the sealing gasket.

Abstract: The invention relates to a removable stabilizer for a spacer casing (24a-24f) of an electrical installation of the GIS type (20), the spacer casing (24a-24f) comprising a first opening (33) as well as a conductor (30b) provided with a bore (34), the removable stabilizer (29) comprising a plug (29a) configured to be introduced via the first opening (33) into the spacer casing (24a-24f), the plug being designed to penetrate into the bore (34) of the conductor (30b) so as to block said conductor (30b) against moving in translation after said spacer casing (24a-24f) has been put to atmospheric pressure.

Abstract: A fastener device for a gas-insulated substation (GIS) type installation comprising a threaded shank and a ring including a duct configured to receive the threaded shank, the ring being housed in a supporting insulator of the invention.

Abstract: An electrical insulator disk has central recesses and peripheral recesses to enable the disk to be mounted floatingly relative to flanges between which the disk is held and to a linear conductor that extends through the disk.

Abstract: A device for controlling a circuit-breaker intended for opening and closing this electric power cut-off device comprising a mobile contact, this control device comprising a motor with a rotary output shaft and being connected to power supply means and actuating means transforming the output displacement of the motor into a displacement of the contact, this device also comprising a mechanical spring arrangement involved in opening and closing the contact. The actuation means include a set of jointed elements providing the connection of the rotary shaft and of the ring, and, in the closed position of the contact, the set of jointed elements is near a dead centre position, a so-called open dead centre, the opening spring being only able to drive it towards the open position upon moving past this dead centre during opening.

Abstract: The invention relates to a device for controlling a circuit-breaker intended for opening and closing this electric power cut-off device comprising a mobile contact, this control device comprising a motor (3) with a rotary output shaft (12) and being connected to power supply means (4-9) and actuating means transforming the output displacement of the motor into a displacement of the contact, this device also comprising a mechanical spring arrangement involved in opening and closing the contact. According to the invention, the actuation means include a set of jointed elements providing the connection of the rotary shaft and of the ring, and, in the closed position of the contact, the set of jointed elements is near a dead centre position, a so-called open dead centre, the opening spring (15) being only able to drive it towards the open position upon moving past this dead centre during opening.

Abstract: The capacitor of high thermal stability includes a high-voltage electrode (HT) extending in a longitudinal direction (AX), a cylindrical printed circuit (CI) coaxially surrounding said high-voltage electrode and including an electrically conductive track forming a low-voltage electrode (BT), and a frame (CH) having a cylindrical inside surface (SI) coaxially surrounding said cylindrical printed circuit (CI). The printed circuit is slit along a generatrix (G1) of the cylinder that it forms and it is rigidly fixed to the inside surface by a fixing point (F1, F2). The frame includes guide means (A1, A2) for holding said printed circuit (CI) near the inside surface (SI) whilst allowing it to expand along said inside surface of the frame. This provides a capacitor of high thermal stability and very simple construction which is suitable for carrying out measurements on a gas-insulated high-voltage electrical line.
