Single-core mineral-insulated sheathed cables consist of a live inner core (heating wire) that is shielded against the metal sheath with magnesium oxide as an insulator. The diameter and quality of the inner core in particular have an influence on the resistance of the cable and therefore on the heating capacity of the heating conductor. A high-quality sheath material determines the maximum operating temperature and resistance under certain environmental influences. We will be happy to cut your mineral-insulated sheathed heating cable to length or assemble it with attached cold ends or power connections.

We also offer customized versions of sheath materials made of Hastalloy, Haynes or stainless steel or specific resistances Ohm/m. We look forward to your inquiry.
