About:

The Okonite FMR cable features a bare copper conductor, which is known for its excellent conductivity and durability. The insulation material used in this cable is EPDM (Ethylene Propylene Diene Monomer), which is resistant to heat, moisture, and various chemicals. The cable designation "XHHW-2" indicates that it has excellent thermal and moisture resistance properties, suitable for both dry and wet locations at temperatures up to 90°C. The "RW90" rating specifies that the cable can handle 600 volts in wet or dry environments at temperatures up to 90°C.

Also Known As:

• Okonite XHHW-2 Cable
• EPDM Insulated Copper Cable
• Bare Copper Control Cable

Application:

Okonite-FMR Type XHH or XHHW-2 600/1000V Power and Control Cables are
recommended for general low voltage power and control applications. Okonite-FMR flame retardant insulated power cables may be used in generating plants, substations and industrial plants. These cables may be installed in wet or dry locations, indoors or outdoors, in raceways, underground ducts, cable tray (size 1/0 AWG and larger per NEC article 392.10(B)(1)) or lashed to a messenger for aerial installation.

Standards:

• XHHW-2: This indicates compliance with standards for cross-linked high heat-resistant water-resistant insulated wire.
• RW90: Ensures the cable is rated for 600 volts in wet or dry conditions up to 90°C.
• NEC (National Electrical Code): The cable adheres to the safety standards outlined in the NEC for installation and use in accordance with various environmental and operational conditions.
• UL (Underwriters Laboratories) listed: This ensures that the cable has been tested for safety and performance by UL, a globally recognized safety certification organization.

Construction:

• Conductor: Uncoated soft copper per ASTM B-3. Sizes smaller than #8 are compress stranded per ASTM B-8. Sizes #8 and larger are compact stranded per ASTM B-496.
• Insulation: Meets or exceeds all requirements of ICEA S-95-658, NEMA WC-70, UL 44 and CSA C22.2 No.38.  Listed by Underwriters Laboratories, Inc. as Type XHH or XHHW-2, VW-1. 0
