Mineral insulated sheathed heating cable
with attached cold ends

Mineral-insulated sheathed heating conductor, consists of a live inner core (heating wire), which is shielded against the metal sheath with magnesium oxide in the heating part and cold part. The cold ends are attached to the heating section by means of a vacuum-compatible and temperature-resistant connecting sleeve which is welded to the heating section and cold section. It causes a slight expansion of the outer diameter, which is negligible in a large number of applications.

The advantage of sheathed heating cables with attached cold ends lies in the clear definition and tight tolerances of heating part and cold part lengths and the high temperature stability up to 800°C. The special feature of our customized solution is that you can define heating part and cold lead lengths according to your requirements using the table below. In addition, we offer you a wide range of individual solutions. We will be pleased to assemble your sheathed heatsealing band with attached cold ends with ceramic current connections or stranded wires.

Components of a sheathed heating conductor with attached cold ends

Design of a heatsealing band with attached cold ends, the lengths of the heating elements and cold sections can be freely selected by the customer. Of course, we will be happy to assist you with the heatsealing band calculation and are available to answer any questions you may have in connection with your heating application.
