An MI cable is a unique cable used in environments with high temperatures due to its low flammability. Moreover, it is resistant to oxidation. Its metal sheath protects the conductor wires against oxidation when subjected to wet or chemically active environments.
Since the cable is inorganically made, it has nothing to burn, a reason why it does not contribute to further combustion. Further, the MgO is resistant to vapor transmission, flames, and gases within the object connected to the cable.
Thus, its corrosion resistance capabilities make the cable effective in areas where replacement and failure could be risky or even impossible. For instance, the MI cable is used by nuclear plants to keep an eye on temperatures. In such environments, it is extremely dangerous if the instruments for controlling temperatures receive inaccurate readings. Moreover, the environment is highly risky for repairs and replacements.
The MI cable is an excellent option for heating and power (it prevents and protects from fire in civil and industrial applications), in addition to electrical heat tracing (building and industrial processes).
In general, the MI cable assemblies are ideal for instrumentation, power, control, and thermocouple applications in designated areas. Its outer metal sheath is made of copper, which is approved to be a ground conductor. Moreover, the cable has a high current rating to meet all power applications virtually.
The MI cables are suitable for the following conditions:
The MI cable does not degrade or weaken with age. Therefore, it lasts a lifetime.
