Abstract
Abstract Electrically insulating connection element comprising two armatures forming shoulders, connected by a junction element comprising wires made of an inorganic substance, more particularly glass, wound on a cylindrical support so as to constitute a cylindrical covering ended by two caps each bearing against the shoulder of an armature, the cylindrical support of the wire covering being radially slightly deformable and constituted preferably by wound wires made of the same inorganic material, with a much shorter pitch than that of the cylindrical covering.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
109 words
An electrically insulating connection element comprising two metallic armatures having shoulders of substantially hemispherical shape facing away from each other, a link element in the form of a cylindrical support connecting said armatures, a winding of wires made of an inorganic substance wound on said cylindrical support and forming a cylindrical covering thereof, said cylindrical covering terminating at its ends in two caps each bearing against the shoulder of a respective armature, said cylindrical support also comprising at its periphery wound wires of an inorganic substance, with the winding pitch of the wires of the cylindrical support being much shorter than that of the wires of the cylindrical covering.
Claim 2
Dependent Claim
109 words
An electrically insulating connection element comprising two metallic armatures having shoulders of substantially hemispherical shape facing away from each other, a link element in the form of a cylindrical support connecting said armatures, a winding of wires made of an inorganic substance wound on said cylindrical support and forming a cylindrical covering thereof, said cylindrical covering terminating at its ends in two caps each bearing against the shoulder of a respective armature, said cylindrical support also comprising at its periphery wound wires of an inorganic substance, with the winding pitch of the wires of the cylindrical support being much shorter than that of the wires of the cylindrical covering.
Claim 3
Dependent Claim
19 words
The connection element according to claim 1, wherein: the cylindrical support is a tube filled with electrically insulating fluid.
Claim 4
Dependent Claim
15 words
The connection element according to claim 1, wherein: each cap is surrounded by a collar.
Claim 5
Dependent Claim
40 words
The connection element according to claim 3, wherein; the collars at each end of the link element are each constituted by a winding of wires made of the same inorganic substance as the caps and having a very small pitch.
Claim 6
Dependent Claim
56 words
The connection element according to claim 4, for the electrical insulation of elements under high electrical tension, said element further including a metallic voltage distribution ring connected to each armature, said rings being arranged in front of the places of maximum temperature level of the connection element in the absence of the metallic voltage distribution rings.
Claim 7
Dependent Claim
56 words
The connection element according to claim 1, for the electrical insulation of elements under high electrical tension, said element further including a metallic voltage distribution ring connected to each armature, said rings being arranged in front of the places of maximum temperature level of the connection element in the absence of the metallic voltage distribution rings.
