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

A Uncoated, Stranded Copper Conductor

B Insulation - Okonite

C Jacket - Okoseal

Insulation
Okonite is Okonite's trade name for its ethylene propylene based insulation. Okonite insulation is heat resistant, mechanically rugged, and exceptionally moisture resistant. This insulation provides an excellent balance of properties for a low voltage power cable.

Applications
For use in branch circuits up to 600V. Rated 90°C wet or dry for use in conduits, underground ducts and aerial circuits in accordance with the National Electric Code. It is applicable for cable tray use on sizes 4/0 and larger and is sunlight resistant. This construction combines the high dielectric and flexibility characteristics of EPR and PVC to resist the hostile oil environments in refinery use and permits ease of low friction installation. The jacket is UL rated Oil Resistant II.

Specifications
Conductor: Uncoated copper Class B stranded per ASTM B-8.

Insulation: Okonite (EPR) meets or exceeds all requirements of ICEA S-95-658, NEMA WC-70 and UL Standard 44.

Jacket: Okoseal (PVC) meets or exceeds the requirements of ICEA S-95-658, NEMA WC70 and UL 1581, Class 43 PVC (90°C rated PVC jacket).

Listed by Underwriters Laboratories, Inc. under miscellaneous wire category as RHW-2/PVC. Sizes 4/0 & larger are also marked "for CT-Use".

(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 318-11.
