Insulation
Okonite-FMR is Okonite’s trade name for its heat, moisture, flame and chemically resistant, mechanically rugged ethylene-propylene insulation compound. It is flame retardant and will pass both the 70,000 BTU/hour and 210,000 BTU/hour tray flame test. Its physical properties and flame retardancy permit its use without a jacket on the single conductors thus providing a substantially smaller overall diameter control cable.

The properties of Okonite-FMR insulation substantially enhance the well known features of ethylene propylene rubber insulations.

Nuclear qualified Okonite/FMR cables that meet IEEE Standard - 383 and LOCA criteria are available on special order.


Shield
The shield system consists of a 5 mil copper tape which is longitudinally applied over the extruded belt and fill. The Longitudinal Corrugated Shield (LCS) maintains uniformly low resistance and a low reactance path for optimum shielding against external high frequency interference.

Overall Jacket
The Okolon jacket is a vulcanized chlorosulfonated polyethylene compound. This combination construction assures circuit security because of its high mechanical strength and excellent resistance to moisture, ozone, oil and most chemicals.

Applications
Okonite-FMR 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 where electrostatic shielding is required. They may be installed in conduits, ducts, cable troughs, trays, messenger supported, or directly buried in the earth.

Specifications
Conductors: Coated copper per ASTM B-33, Class B stranded per ASTM B-8.

Insulation: Okonite-FMR meets or exceeds the electrical and physical requirements of ICEA S-75-532.

Color Coding: Base colors and tracers per ICEA Method 1 Table E-1.  Sequence shown bellow.

Assembly: Conductors cabled using flame and moisture resistant fillers.

Overall Jacket: The Okolon compound meets or exceeds the requirements of ICEA S-75-532
