Mica / Glass Composites (MGT, MGS, MGR) and Instrumentation/Control Multiconductor cables
Mica is applied as a tape, providing the primary insulation and first line of defence against deterioration of critical circuits. Additionally, an overall glass braid is applied over the mica tape, to hold it in place, and to provide conductor colouration. Much used as low voltage and instrumentation cables requiring specified Fire Resistance for the safe shutdown of process plant and equipment. "Lead wire" versions are unaffected by flame, fuels, solvents, most acids, alkalis and oils. Popular for the wiring of ovens and other high temperature equipment, the standard conductor material is oxygen-free high-conductivity 27% nickel-coated copper. MGT lead wires are unaffected by flame, fuels, solvents most acids, alkalis and oils and pass IEEE-383 70,000 BTU/HR Flame Test. "Flexing" oil resistant versions are available for applications where cables will continuously move at high temperatures. Cleanstrip and non-fraying, anti-itch lead wire versions are available for high-speed automated cut and strip machines.
300 or 600 Volt grade multicore/pair, Instrumentation/Control cables are also available. These Instrumentation and control 500°C multi-conductor instrumentation/control cables are designed for use for a wide variety of applications which include: electro thermal and electromechanical installations and in industries such as metallurgy chemicals, nuclear, aeronautic, railway and shipbuilding, plastics processing etc.
