## Abstract

A system includes a partition element (4) and a first component (1) which is arranged on a first side of the partition element (4). The first component (1) includes at least one conductor (9), and the partition element (4) includes an associated feedthrough (5) for inserting and feeding through the conductor (9) and for electrically contacting the conductor (9) on a second side of the partition element (4) located opposite the first side. The conductor (9) forms a form-fitting connection to the feedthrough (5) and is pressed into the feedthrough (5).

## Claims

### Claim 1

Method for producing a system, comprising the following steps:
providing a partition element;
providing a first component with at least one conductor;
equipping the partition element with a feedthrough for inserting and feeding through the associated at least one conductor, wherein the feedthrough is configured as a press fit;
shrinking a diameter of the conductor at least in a section of the conductor to be inserted into and fed through the feedthrough by cooling the conductor until the conductor can be inserted into and fed through the feedthrough; and
inserting and feeding the conductor from a first side into and through the feedthrough of the partition element so as to provide electrical contacting on a second side of the partition element located opposite the first side.

### Claim 2 (depends on 1)

Method according to claim 1, further comprising adjusting a temperature of the at least one conductor to an operating temperature of the partition element, the at least one conductor forming a form-fitting connection to and a press fit with the feedthrough of the partition element.

### Claim 3 (depends on 1)

Method according to claim 1, further comprising aluminising at least one section of the at least one conductor, the at least one section of the at least one conductor inserted into and accommodated in the feedthrough being preferably aluminised.

### Claim 4 (depends on 1)

Method according to claim 1, further comprising inserting the conductor into an aluminium sleeve or an aluminium tube and connecting the aluminium sleeve or the aluminium tube in a form-fitting manner to the conductor.

### Claim 5 (depends on 1)

Method according to claim 1, further comprising applying an oxide layer or anodised coating to at least one section of the at least one conductor.
