Product Information

Specification

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.

Overall Jacket

The overall jacket is a cross-linked polyethylene compound. This combination construction assures circuit security because of its high mechanical strength and excellent resistance to moisture, ozone, oil and many chemicals.

Applications

Okonite FMR-N Instrumentation Cables are recommended for use in power generating plants and in substations; designed especially for critical circuits where continuity of service is of prime importance. This premium quality instrumentation 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.

Specifications

Conductors: Tinned copper per ASTM B-33, Class B stranded per ASTM B-8.
Insulation: Okonite FMR-N meets or exceeds the electrical and physical requirements of ICEA S-73-532
Conductor Identification: Pigmented black and white in pairs, black, white and red in triads; white conductor numerically printed for group identification.
Assembly: Pairs or triads assembled with left-hand lay. Flame-retardant, non-wicking fillers included where required to provide a round cable.
Cable Shield: Copper/Polyester/Nomex tape overlapped to provide 100% coverage, and a 7-strand tinned copper drain wire, same size as conductor.
Overall Jacket: The X-Olene FMR compound meets or exceeds the requirements of thermoset jackets given in ICEA S-73-532.
