Can You Direct Bury MI Cable?

As an experienced engineer or contractor, you might be wondering if it is possible to direct bury the MI cable.

By now, you probably know the advantages of the fire-rated MI cable. You might have seen the cable in the field, and you’re still uncertain of installing it in your next project.

Worry no more. We understand your concerns because the mineral wire might be intimidating at first sight.

So, the organic construction of the MI cable gives it excellent capabilities to resist heat and fire. The cable can easily sustain heavy current overloads and high temperatures. Moreover, neither does it emit toxic substances, smoke nor allow flame propagation.

The fireproof abilities of the Mi cable make it the best choice for connecting various operations like:

• • • Motor operated valves
    • Control stations
    • Plant shutdown systems
    • Other instruments that must be functional under live fire conditions

These cables are extremely reliable as control and power cables, especially in hotels, hospitals, fire pumps, alarm systems, and communication circuits.

A unique feature about the MI cable is that it never deteriorates at low temperatures. Moreover, it is never affected by extreme changes in temperature because the cable is solid and moisture resistant.

It is designed with an extruded metal sheath made of copper to make it impervious to liquids. Therefore, you can rely on the cable in any environment because neither corrosive solutions, water, or process liquids can affect it.

So, go ahead and make your move to direct bury the MI wire because it is extremely safe.
