Insulation
Okonite FMR-N is Okonite’s trade name for its heat, moisture, flame and chemically resistant, mechanically rugged nuclear plant qualified ethylene-propylene insulation compound. Its physical properties and flame retardency permit its use without a jacket on the single conductors.
The properties of Okonite FMR-N insulation substantially enhance the well known features of ethylene propylene rubber insulations.
Nuclear qualified Okonite FMR-N cables meet IEEE Standard - 383 LOCA and flame test criteria.
Applications
Okonite FMR-N Power and Control Cables are recommended for use in either power generating plants and in substations; designed especially for critical circuits where continuity of service is of prime importance. This premium quality control cable is recommended for wet or dry, ac or dc service at conductor temperatures to 90°C. They may be installed in conduits, ducts, cable troughs,trays, messenger supported, or directly buried in the earth.
