What Is Mineral Insulated Metal Sheathed Cable?

Jan. 02, 2019

Mineral Insulated Cable is a type of bendable metal cable used in temperature sensor manufacture. It is also known as Mineral insulated metal sheath or MIMS for short. Mineral insulated cable is made from a seamless metal tube, tightly packed with Magnesium Oxide powder. Thermocouple wires run through the metal tube and the magnesium oxide powder helps keep these wires insulated and separated.

Mineral Insulated Metal Sheathed Cable is standardised under the international standard IEC 61515 (Mineral insulated metal-sheathed thermocouple cables and thermocouples). Mineral insulated temperature sensors can come in many different designs. 

MI Cable was developed to fill the need for an electrical cable which would have high heat and water resistance and would not be bulky or difficult to install. It provides a general wiring system which is suitable for a great variety of applications for systems with voltages up to and including 600 V. Type MI is approved for use in almost any type of installation.
