A 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. In particular, the diameter and the nature of the inner core have an influence on the resistance and thus on the heating capacity of the heating conductor. A high-quality sheath material determines the maximum operating temperature and resistance under certain environmental influences.
The special thing about our customized solution is that you can define heating part and cold part lengths according to your requirements using the table below. We offer you an enormously wide range of customized solutions. We will be pleased to assemble your sheathed heatsealing band with transitionless cold ends with ceramic current connections or stranded wires. Of course, we will be happy to support you in the calculation of the heatsealing band and are available to answer any questions you may have in connection with your heating application. Special designs are already possible from small quantities. Please contact us at any time.
Please feel free to send us a message or inquiry. Please tell us the length of the heating part, as well as the cold part. We are looking forward to your inquiry.
