Abstract (en)
[origin: CN113365375A] Disclosed is a method for producing an electrical heating device with an electrical heating element, which is arranged in the interior of a multi-part tubular metal jacket embedded in an electrically insulating material, wherein the electrical heating device has, within the multi-part tubular metal jacket, on at least one end, an unheated area, in which, during operation of the electrical heating device, electrical current flows at least also through at least one connection wire, and/or at least one connection sleeve and/or at least one connection pin, which is in electrical contact with the electrical heating element, and further has a heated area, in which, during operation of the electrical heating device, electrical current flows only through a section of the electrical heating element running in the heated area. The electrical heating device which can be produced with this method, is also disclosed.
