Abstract: A compression sealing gasket having a main body of general planar extension, or extending in a plane, including an inner side and an outer side, and end faces, which delimit the gasket along an axis perpendicular to the plane, and connect the inner side and the outer side, made of an elastomer material, the main body having a first extension, along the axis, at least one of the inner side and the outer side being provided with a lip which has a second extension, along the axis perpendicular to the plane, less than the first extension.

Abstract: A safety valve for a pressure barrier plate of a gas insulated switchgear. The safety valve including a longitudinal sleeve extending along an axis and having a first end and a second end, a pin extending in the sleeve between a first end and a second end, the first end of the pin bearing a first end cap, the second end of the pin bearing a second end cap, a first compression spring in a first compartment inside the sleeve, a second compression spring in a second compartment inside the sleeve, the first spring and the second spring respectively pushing the second end cap and the first end cap towards opposite directions along the axis.

Abstract: A compression sealing gasket including an annular main body compression sealing gasket having an annular main body made of an elastomer material and having an annular radially outer face and an annular radially inner face parallel and coaxial to each other, wherein at least one of the radially outer face and the radially inner face includes at least one first thin layer, made of metal or soft metal or PTFE, and having a thickness of between 1 nm and 1 mm.

Abstract: The invention relates to a mould for moulding a component with one or more inserts, the mould comprising a mould body for defining in part the shape of the component, and at least one insert holder for holding an insert within the mould body. Each insert holder is movably supported such it can move relative to the mould body in a direction of shrinkage of the component, and wherein the mould further comprises a biasing means to bias each insert holder to a first position relative to the mould body. The invention also relates to a method of moulding.

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 insulating support (20) for insulating an electrical conductor contained in aligned casing portions (34, 35), is held in a housing (39) defined by the flanges (36, 37) for joining the casing portions (34, 35) together, the flanges presenting contact faces (38) around the periphery (24) of the support (20). A single sealing gasket (41) is sufficient to prevent the atmosphere in the casing leaking to the outside, and that simplifies assembly of the electrical equipment, while at the same time protecting the support (20) from the outside. For application to medium- and high-voltage electrical equipment.

Abstract: To control a switch apparatus having two interrupters, such as a busbar disconnector and a grounding disconnector, there is provided a rotary control shaft arranged away from, and at right angles to, the planes of straight line motion of the movable contacts, at least one disk cam fastened to the control shaft and having two distinct internal cam grooves, and two pairs of levers hinged to each other. One of the levers has one end hinged at a fixed point while its other end is hinged to the other lever, which is itself hinged to one of the movable contacts, a spigot being located between the two ends of each of the levers that has one end hinged at a fixed point, the spigot being engaged in one of the cam grooves so as to constitute a cam follower.
