Mineral-Insulated Copper-Sheathed Cable

A lifeline that holds at 950°C in open flame.

Magnesium-oxide mineral insulation inside a seamless copper sheath: a fully inorganic construction that cannot burn, emits no smoke and no toxins, and keeps circuits alive for 3 hours at 950°C under impact and water spray. The ultimate safeguard for fire services, emergency power and crowded venues.
