Insulation
Okoguard is Okonite's registered trade name for its exclusive ethylene-propylene rubber (EPR) based, thermosetting compound, whose optimum balance of electrical and physical properties is unequalled in other solid dielectrics. Okoguard insulation, with the distinctive red color and a totally integrated EPR system, provides the optimum balance of electrical and physical properties for long, problem free service.

Jacket
The Okolon jacket on this cable is a vulcanized chlorosulfonated polyethylene based compound which is mechanically rugged, flame, radiation, oil and sunlight resistant.

Applications
Okoguard-Okolon 8kV cables are heavy duty nonshielded cables designed for use at up to 8kV phase-to-phase in wet or dry locations in accordance with NEC Section 310.6 and Table 310.63.

Single conductor cables may be installed in a raceway, in free air on insulators; as connectors between transformers; as aerial lines on pole tops or preassembled or fieldspun to a messenger.

Single conductors may be installed in triplexed or random lay in any raceway or duct in wet or dry locations, or in open runs as permitted by NEC Articles 396.

Specifications
Conductors: Annealed uncoated copper compact stranded per ASTM B-496.

Strand Screen: Extruded semiconducting EPR strand screen. Meets or exceeds electrical and physical requirements of ICEA S96-659/NEMA WC71 and UL 1072.

Insulation: Meets or exceeds electrical and physical requirements of ICEA S96-659/NEMA WC71, Table 310.63 of the NEC and UL 1072.

Jacket: Meets or exceeds electrical and physical requirements of ICEA S96-659/NEMA WC71 for chlorosulfonated polyethylene jackets, Table 310.63 of the NEC, and UL 1072.

UL Listed as Type MV-90, sunlight resistant in accordance with UL 1072.

1/C 8kV non-shielded cables can surface discharge in service when in a random phase spacing or when in contact with grounded surfaces.

Aluminum Okopact Conductors

(1) Aluminum Okopact conductors are available on special order. To order aluminum Okopact conductors, change the first three digits of the catalog number from 115 to 135.

Ampacities

(2) Ampacities are in accordance with Table 310.73 of the NEC for three single Type MV-90 conductors, or single conductors twisted together (triplexed) and installed in an isolated conduit in air at an ambient temperature of 40°C and a conductor temperature of 90°C.

(3) Ampacities are in accordance with Table 310.77 of the NEC for three single conductors or triplexed cable in one underground raceway, three feet deep with a conductor temperature of 90°C, 100% Load Factor, an ambient earth temperature of 20°C, and thermal resistance (RHO) of 90.

Refer to the NEC, IEEE/ICEA S-135 Power Cable Ampacities, or the Okonite Engineering Data Bulletin for other ambient temperatures, circuit configurations or installation requirements.

(4) Recommended size of rigid or nonmetallic conduit for three conductors based on 40% maximum fill.

*The jam ratio, conduit I.D. to cable O.D. should be checked to avoid possible jamming.
