Okonite Okoguard-Okolon® Type RHH or RHW-2 or USE-2, VW-1 600V Power and Control Copper Conductor/90°C Wet or Dry For Cable Tray Use

A Uncoated, Stranded Copper Conductor

B Composite Okoguard-Okolon Insulation

Composite Insulation
Okoguard-Okolon is Okonite's trade name for its ethylene propylene-chlorosulfonated polyethylene composite insulation. The combination of the two materials provides a dielectric which requires no outer covering and which has excellent resistance to heat, mechanical abuse, flame, weathering, most oils, acids and alkalies.

The advantages of Okoguard EPR, with a proven track record of over 30 years as a medium voltage insulation, are now offered in low voltage cables.

Applications
Okoguard-Okolon 600 Volt Power and Control Cables are recommended for use in all low voltage circuits where continuity of service is the prime consideration. These cables may be installed in wet or dry locations, indoors or outdoors, in raceways, underground ducts, directly buried in the earth, or lashed to a messenger for aerial installation. These cables may also be installed in cable tray (size 1/0 AWG and larger per NEC 392.2).

Specifications
Conductor: Uncoated copper solid per ASTM-B-3, compress stranded per ASTM B-8, or compact per ASTM B-496.

Insulation: Meets or exceeds all requirements of ICEA S-95-658, NEMA WC-70 and UL Standards 44 and 854.

Listed by Underwriters Laboratories, Inc. as Type RHH or RHW-2 or USE-2, VW-1. Sizes 1/0 AWG and larger are also marked "sunlight resistant, for use in cable tray".

(1) Ampacities are based on Table 310.16 of the National Electrical Code for these 90°C rated conductors at an ambient temperature of 30°C. The 75°C wet column is provided for additional information.

The ampacities shown apply to open runs of cable, installation in any approved raceway, direct burial in the earth, or as aerial cable on a messenger. Derating for more than three current carrying conductors within a raceway is in accordance with Note 8 to NEC Tables 310.16 through 310.19.

(2) Based on three (3) conductors in a single enclosed or exposed conduit. Capacities based on 40°C air ambient using ICEA methods. For 30°C ambient multiply values by 1.10; for 50°C multiply by .90. For other ambients or installation conditions refer to Engineering Data Book EHB-90.

The ampacities shown also apply to cables installed in cable tray in accordance with NEC Section 392.11.
