Mineral insulated mantle heat conductor with seamless cold ends (customer-specific)



Mineral insulated heat conductors, made up of a live inner wire (filament) which is insulated against the metal sheath with magnesium oxide in the hot part and in the cold part. In particular, the diameter and the composition of the inner wires influence the resistance of the cabling and therefore the heating power of the heat conductor. A high quality sheath material decides the maximum usage temperature and resistance under particular surrounding conditions.


What is special about our customer-specific solution is that the lengths of the hot part and the cool part can be defined with the help of the table below according to your wishes. Moreover, we offer you a large selection of individual solutions.


We will be happy to make your sheath heat conductor with seamless cold ends ready-made with ceramic power connectors or extension cables.


We will of course be happy to support you in calculating the heat conductor and to answer questions you have in connection with your heating application.

We are looking forward to your inquiry.
