Mineral insulated cable (Mineral insulated cable) is a kind of cable in which a copper conductor core is wrapped with a copper sheath, and magnesium oxide powder is used as an inorganic insulating material to isolate the conductor and the sheath. The outermost layer can be appropriately selected as required. Commonly known as MICC or MI cable. There is a similar cable that uses metal instead of copper sheath to wrap the core wire and insulating material, called mineral insulated metal sheathed cable (Mineral insulated metal sheathed cable (MIMS Cable))。
