  • the connecting lines can be formed by a plurality or a plurality of individual wires composed of strands or in each case by a single solid wire, wherein they consist of a high-temperature-resistant alloy, for example a nickel alloy or a chromium-nickel alloy. It is particularly expedient if the connecting lines are provided with high-temperature-resistant insulation, for example braided fiberglass insulation, essentially over their entire length.
  • the springback properties of the connecting lines are aligned in their position with respect to the electric hotplate by the fact that their inner ends are stiff or rigid over a much larger diameter than their diameter are designed to be substantially more rigid than their main sections lying between the ends and that these inner ends are connected to the respectively associated, correspondingly rigid connection wire are connected so that the connection point thus formed is secured with almost no play relative to the insulating piece.
