System 2200 MI Wiring Alloy 825 Cable
nVent PYROTENAX System 2200 mineral insulated (MI) wiring cable is a range of MI wiring cable, with an Alloy 825 sheath and solid nickel conductors (600 V). It has a continuous exposure temperature of 1238 °F/670 °C and can withstand rapid-rise temperature excursions to 2200 °F/1200 °C. The inorganic cable construction provides superior fire resistance under conditions of both high heat flux and high temperature. Common applications include control/signal/instrumentation of 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.

Features
- Simple and fast to install: typically supplied as a factory-assembled Duoterm unit complete with terminations at each end, allowing for immediate installation in the field
- Ideal for hazardous areas: the simplified installation of MI cable means that conduit systems and explosion-proof seals are not required, just connect the cable directly to the equipment or junction box
- Increased safety: made of inorganic materials, it 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
- Fully tested and compliant: using the UL2196 electrical test procedure it maintains electrical circuit integrity for 2 hours during exposure to the UL 1709 fire test. The UL 1709 test, referenced in API 2218, replicates an intense hydrocarbon fire, reaching 1093 °C / 2000 °F in 5 minutes when subjected to a heat flux of 65,000 BTU/ft² hr (200 kW/m²) in an enclosed furnace
- Reliable during long life: 30 year product warranty available
