System 2000 MI Wiring Alloy 825 Cable

nVent PYROTENAX System 2000 mineral insulated (MI) wiring cable is a range of MI wiring cable, with an Alloy 825 sheath and nickel-clad copper conductors (600 V). It has a continuous exposure temperature of 1238 °F/670 °C and can withstand rapid-rise temperature excursions to 2000 °F/1093 °C. The inorganic cable construction provides superior fire resistance under conditions of both high heat flux and high temperature. Common applications include the supply of power to motor operated valves during fire exposure ensuring that valves can be safely controlled and closed when required. It is typically supplied as a factory-assembled wiring unit complete with terminations at each end.
