Description:

• 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.

• nVent PYROTENAX System 2200 fire-rated mineral insulated (MI) wiring cables facilitate the controlled shutdown of critical processes and systems in the event of a hydrocarbon flash fire in both nonhazardous and hazardous locations.

• Using the electrical test procedure described in UL2196, System 2200 MI cable 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 2000°F (1093°C) in 5 minutes when subjected to a heat flux of 65,000 BTU / ft2 hr (200 kW / m2 ) in an enclosed furnace.

• System 2200 wiring cable is constructed with an Alloy 825 sheath and solid nickel conductors that allow continuous exposure temperatures to 1238°F (670°C) and withstand rapid- rise temperature excursions to 2200°F (1200°C). 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.

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

System 2200 MI cable may be used for power, control, and communication wiring in the following environments:

• Petrochemical – to protect critical systems in the event of a hydrocarbon flash fire
• Petrochemical and mining – in hazardous areas to provide a gas path block
• Manufacturing – in areas of extreme heat, around furnaces, etc.
• Tunnels and confined spaces – MI cables do not burn; no smoke generated
• Nuclear and fossil fuel power generation plants – for wiring to equipment where heat or radiation may be of concern
• Pulp and paper – where corrosives are present System 2200 wiring cable is typically supplied as a factory-assembled Duoterm unit complete with terminations at each end, allowing for immediate installation in the field. In hazardous areas, the simplified installation of MI cable means that conduit systems and explosion-proof seals are not required; simply connect the cable directly to the equipment or junction box.

SYSTEM 2200

System 2200 has been independently tested in hydrocarbon pit fires up to temperatures of 2030°F (1110°C) and meets the requirements of national electrical codes. For additional information on factory-assembled Duoterm units or bulk cable and field-installed terminations,
