Depending on the cable's construction, insulation such as magnesium oxide (Mgo), MICA tapes, and polymers are used to protect the solid or stranded conductors. The insulation is then shielded by an outer sheath, which is typically made of copper, steel wire armoured wire, or a fire-resistant polymeric sheath, each of which performs differently under fire conditions. To meet the requirements of a fire cable, the construction mus...
