*Upon request, we offer calibration services up to 1100Ā°C for Okazaki type K and N mineral insulated cable. This specialized calibration, complete with a certification, is available exclusively for custom cable requests.

On this page we explain all common used sheath materials and their advantages compared to other sheath materials for MI cable.

Non standard stock items – supplied on request

Due to our network of world wide manufacturers, we can offer a wide range of MI cable with special sheath materials in combination with non conventional sizes and thermoucouple wires. Get in contact to request a quote for a special MI Cable.

Please be aware that desired cable, sheath and/or wire combinations do not always apply, due to specific cable and/or wire characteristics. Contact Kamet Trading for the best solution in material combination and sizing for your project.

*The TC wires will be thinner with the heavy wall design. If thicker wires than normal are needed, this will be a case by case quotation.
** Percentages may vary due to availabilty of starting tube lenghts. 
***In regards to the Hastelloy-X and Hastelloy-C, we can offer dual wall and each item will vary.

Class of tolerance

The importance of industry standards is, that it ensures traceability and constant quality of products. The following industry standards are defined; IEC 60584-1 class 1, IEC 60584-1 class 2, IEC 60584-1 class 3, ASTM E230, ASTM E230 special limits and ‘class 1 on best effort basis’. Not all types of cable can be produced according to a certain type of class. Please contact us to get informed according to which norm, your specific cable is supplied. 

Delivery time

Cables in stock can be shipped out the same day or the day that is determined as customer specific delivery date. For non standard stock items, delivery times may vary. Below you find a rough estimate of delivery times for non stock items. Please be informed that delivery time on order confirmation is leading.

MI TC cable 18 weeks 
MI cable with platinum wire 6 weeks 
MI cable with platinum sheath material 4-5 weeks
