## Abstract

A high-voltage bushing has an internal conductor and an insulating body which surrounds the internal conductor along its longitudinal direction. The internal conductor is routed out of the insulating body at a head end of the high-voltage bushing. A fastening flange is arranged on the insulating body at an end opposite the head end. An outer housing encloses the internal conductor and the insulating body from the fastening flange up to and including the head end in a moisture-tight manner. A high-voltage installation has a high-voltage conductor which is routed through a housing wall of the high-voltage installation by way of the novel high-voltage bushing.

## Claims

### Claim 1

A high-voltage bushing, comprising:
an internal conductor;
a head end;
an insulating body surrounding said internal conductor along a longitudinal direction thereof, said internal conductor being routed out of said insulating body at said head end of the high-voltage bushing;
a fastening flange disposed on said insulating body; and
an outer housing enclosing said internal conductor and said insulating body from said fastening flange up to and including said head end in a moisture-tight manner.

### Claim 2 (depends on 1)

The high-voltage bushing according to claim 1, wherein said outer housing is formed of a plurality of separate housing elements and all of said separate housing elements of said housing are connected to one another by adhesive bonding.

### Claim 3 (depends on 2)

The high-voltage bushing according to claim 2, wherein said housing comprises a head fitting at said head end, a foot fitting on said fastening flange, and a connecting pipe connecting said head fitting with said foot fitting.

### Claim 4 (depends on 3)

The high-voltage bushing according to claim 3, wherein said head fitting is composed of a metal, and said head fitting includes an outer current contact and an inner current contact integrated into said housing.

### Claim 5 (depends on 3)

The high-voltage bushing according to claim 3, wherein said head fitting is composed of a metal.

### Claim 6 (depends on 3)

The high-voltage bushing according to claim 3, wherein said head fitting includes an outer current contact integrated into said housing.

### Claim 7 (depends on 3)

The high-voltage bushing according to claim 3, wherein said head fitting includes an inner current contact integrated into said housing.

### Claim 8 (depends on 3)
