## Abstract

This invention relates to a supporting structure for contacts of high-voltage disconnectors, characterized in that it comprises at least one vertical central composite insulator that is stayed by means of at least two inclined insulators, each of which is coupled at a first end to said at least one central composite insulator and at the second opposite end to a base body for said at least one vertical central composite insulator.

## Claims

### Claim 1

A supporting structure for contacts of high-voltage disconnectors, comprising:
at least one vertical central composite insulator that is stayed by means of at least two inclined insulators each of the at least two inclined insulators is coupled at a first end to said at least one central composite insulator and at the second opposite end, to a base body of said at least one vertical central composite insulator.

### Claim 2 (depends on 1)

The support according to claim 1, wherein a central composite insulator composed of a single segment or multiple segments.

### Claim 3 (depends on 1)

### Claim 4 (depends on 3)

The support according to claim 3, wherein said at least two vertical composite insulators comprise four vertical composite insulators.

### Claim 5 (depends on 1)

The support according to claim 1, wherein said at least two vertical central composite insulators have a common intermediate frame for the fixing of said at least two inclined insulators.

### Claim 6 (depends on 1)

The support according to claim 1, wherein said at least two inclined insulators are arranged so that the main axis of symmetry is inclined by an angle between 5° and 40° with respect to the main axis of symmetry of a reference vertical central composite insulator.
