Insulation
Okonite-FMR is Okonite's trade name for its heat, moisture, flame and chemical resistant,
mechanically rugged ethylene-propylene insulating compound.
The single conductors are color coded with solid and tracer colors as required for
proper identification.
The properties of Okonite-FMR insulation substantially enhance the well known features
of ethylene-propylene rubber insulations.
Overall Jacket
The overall jacket is a vulcanized chlorosulfonated polyethylene compound. This
combination construction assures circuit integrity because of its high mechanical strength
and excellent resistance to moisture, ozone, and most chemicals.
Applications
Okonite-FMR Okolon Type TC tray cable is permitted for use on power, lighting, control,
and signal circuits; indoors or outdoors; in cable trays, raceways, direct burial in the
ground, or where supported in outdoor locations by a messenger wire; for Class 1 circuits
as permitted in Article 725 of the NEC; and in cable trays in Class I, Division 2
hazardous locations in industrial establishments where the conditions of maintenance and
supervision assure that only qualified persons will service the installation.
