System 2200


nVent PYROTENAX fire-rated mineral insulated (MI) wiring cables facilitate the controlled shutdown of critical processes and systems in the event of an industrial fire — such as a hydrocarbon flash fire — by ensuring that electrical power is available for critical circuit survival. The heavy duty construction of the PYROTENAX System 2200 wiring cable makes this possible. It utilizes an Alloy 825 sheath along with nickel-clad copper conductors to allow continuous exposure temperatures to 1238°F (670°C) and withstand rapid-rise temperature excursions to 2200°F (1200°C) — this is important as industrial fires can burn very hot. In addition, the sheath provides durability in areas where corrosives may be present.

MI cable is made of inorganic materials and provides zero smoke generation, zero fuel contribution, and zero flame spread. Highly compacted magnesium oxide (MgO) insulation prevents the flow and transmission of explosive gases through the wiring cables.
