The inner cylinder has a variable cylindrical part.

A grommet assembly includes an inner member having a body portion to be inserted into a mounting hole of a panel, and a panel engagement portion formed on the body portion and to be engaged with an opening edge of the mounting hole, a grommet to be mounted to a rear side of the inner member, the grommet including an annular panel contact portion having a seal part to contact a portion of the panel surrounding the mounting hole, and a tubular wire housing portion connected to the panel contact portion and to cover an electric wire such that the electric wire bends with respect to a center axis of the mounting hole and a protruding member to protrude from a rear side of the body portion, the protruding member including a pressing support portion extending along an inner surface of a rear wall of the wire housing portion.

A grommet includes: a water stop portion that has an annular shape and is inserted to a through hole formed in an attachment panel for stopping water; and a first partition wall portion and a second partition wall portion that are unit arranged to project toward a radially inner side of the water stop portion water stop portion. The water stop portion includes: a first contact portion that is capable of coming into contact with a first side surface of a circumference edge portion of the through hole; a second contact portion that is capable of coming into contact with the first side surface; a groove portion formed in an annular shape between the first contact portion and the second contact portion; and a recess/protrusion portion that is formed on a circumferential wall inside the groove portion.

A grommet includes a water stop part having an annular shape that stops water by being inserted into a through hole formed on a mounting panel, and a first partition wall part or a second partition wall part disposed so as to close the annular shape of the water stop part by extending in a radially inner side of the water stop part. The water stop part includes an abutting surface formed in an annular shape capable of coming into contact with one side of a peripheral part of the through hole in an axial direction, and a plurality of claw parts that face the abutting surface in the axial direction, that are capable of coming into contact with another side of the peripheral part of the through hole, and that are intermittently provided in a circumferential direction.

A grommet includes a main body part fitted to a penetration hole penetrating an attachment panel, and a tubular part unified with the main body part so as to have a tubular shape. The tubular part includes a tubular part main body formed continuing from the main body part, and a fold-back part formed continuing from the tubular part main body on a side opposite to a side where the main body part is positioned in the axial direction and that can be folded back to the outside of the tubular part main body. The fold-back part is foldable between an attachment position where the fold-back part is folded back to the outside of the tubular part main body, and a use position where the fold-back part is positioned on the side opposite to the side where the main body part is positioned.

A grommet includes a tapered barrel part and a tape winding spatula part. The tapered barrel part includes a large diameter cylindrical portion, a small diameter cylindrical portion, and an elastic deformation portion disposed between the large diameter cylindrical portion and the small diameter cylindrical portion. A fitting groove to be fitted in a through hole of a panel, is formed on the large diameter cylindrical portion. A thick walled portion is formed on an inner side of the elastic deformation portion. The tape winding spatula part is connected to the small diameter cylindrical portion and holds a wire harness passed through therein.

A grommet includes a ring-shaped water stop portion inserted into a through hole formed in an attachment panel and performing water stopping, a closing portion projecting toward radial inside of the water stop portion and closing a ring shape of the water stop portion, a tube portion extending in a direction crossing an axis direction of the water stop portion and provided to penetrate the closing portion and through which a wire material is inserted, and a handle portion provided in an arch shape with respect to the closing portion with a central axis of the water stop portion serving as a center.

The disclosure relates to a curable mixture, in particular for use in impregnation of paper bushings, comprising (a) a resin composition comprising a bisphenol-A-diglycidylether; a polyglycidylether different from BADGE and/or a cycloaliphatic epoxy resin; a N-glycidyl component; a nano-size or dissolvable toughener; and a silane component, and b) a hardener composition comprising methyltetrahydrophthalic anhydride (MTHPA) and at least one curing accelerator as well as paper bushings impregnated with such mixture and uses of such mixture.

The invention relates to an explosion-proof assembly (22) having an electrically conductive stud (23) made of a material which is not deformable radially. The stud (23) is coaxially surrounded in a central portion (23a) by an electrically insulating, electrically insulating sleeve (30). The sleeve (30) is in turn coaxially surrounded by a connecting portion (41) of a plastically deformable connecting body (40). Plastic deformation of the connecting portion (41) reduces the outer dimension thereof and the connecting portion (41) presses inwardly against the sleeve (30) to form a frictionally engaged form-fitting connection therebetween such that the connecting body (40), the sleeve (30) and the stud (23) form a structural unit with at least one stop surface (26) on the stud (23) resting against a counter stop surface of the sleeve (30).

The invention is concerned with a bushing for high voltage applications and a bushing arrangement including such a bushing. The bushing includes a conductor defining a longitudinal axis (A) through the bushing where the bushing has a central section and a first and a second peripheral section on opposite sides of the central section along the longitudinal axis (A) and includes an optical fibre with a first part (P1) stretching through the central section, the fibre being adapted to detect physical properties being influenced or caused by the operation of the bushing. The sections are sections of a solid condenser core and the bushing further includes an enclosure for a length of fibre that is to exit the bushing, the enclosure being buried in the central section adjacent the surface of the condenser core and having an interior.
