ISOMIL-M - Mineral Insulated Measurement Cables

The inner conductor is generally a low resistive wire (in some cases several wires) which transmits the electrical signal. Conductors of this type are used in measurement and control techniques and thus referred to as sheathed measurement conductors.


Type denotation ISOMIL-M

Example: The type Denotation 2C2A60 designates a cable coil with 2 cores, inner conductors made of cooper, insulation made of MgO (97%), the sheath material 1.4541 and an outer diameter of 6 mm.
