Abstract
An electrical feedthrough is providing that includes a base body, an insulating material, an electrical conductor, a creepage distance extension, and a sealing member. The base body has a through opening extending therethrough. The insulating material is in the through opening. The electrical conductor extends through the insulating material such that a portion of the electrical conductor protrudes from the insulating material. The creepage distance extension surrounds at least a section of the portion. The sealing member is between the insulating material and the creepage distance extension. The sealing member is a seal material that is at least partially mineral and crystalline.

An electrical feedthrough, comprising:
- a base body having a through opening that extends through the base body;
- an insulating material in the through opening;
- an electrical conductor extending through the insulating material such that a portion of the electrical conductor protrudes from the insulating material;
- a creepage distance extension surrounding at least a section of the portion;
- and
- a sealing member between the insulating material and the creepage distance extension,
- wherein the sealing member comprises a seal material that is at least partially mineral and crystalline.
A method for producing an electrical feedthrough, comprising:
- providing a base body having a through opening that extends through a base body;
- providing an electrical conductor into the through opening with at least a portion of the electrical conductor being surrounded by a creepage distance extension;
- providing a sealing member at the creepage distance extension, wherein the sealing member comprises a seal material that is at least partially mineral and crystalline;
- and
- fusing an insulating material to the sealing member and in the through opening such that the portion of the electrical conductor protrudes from the insulating material.
