What are the advantages of Mineral Insulated Copper Cables (MICC) in high-risk environments?

MICC is often considered the “ultimate” fire-resistant cable.

Composition: It consists of copper conductors inside a copper sheath, insulated by compressed magnesium oxide powder.

Pros: It is completely inorganic, meaning it cannot burn, produces zero smoke, and can operate at temperatures near the melting point of copper. It also acts as its own conduit.

Cons: Higher material cost and requires specialized termination skills compared to polymeric cables.
