Abstract:
A method for producing an electrical heating device with the steps of preparing a sleeve from a first material that has a first strength; arranging an electrical heating element in the sleeve; arranging of a filler material in the sleeve, so that parts of the electrical heating element carrying current are electrically isolated from the sleeve and the position of the electrical heating element in the sleeve is fixed, and at least section-wise compression of the sleeve, of the electrical heating element is arranged in sections of the sleeve that are compressed, and of the filler material arranged in sections of the sleeve that are compressed, wherein, before the completion of the at least section-wise compression of the sleeve, in sections to be compressed, a tubular section is arranged that is made from a second material that has a second strength higher than the first strength.
