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 unequaled 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.

The triple tandem extrusion of the screens with the insulation provides optimum electrical characteristics.

Shield
An 8 mil copper longitudinal corrugated shield (LCS) is applied over the extruded semiconducting insulation screen. This construction provides a substantially lower shield resistance compared with a tight helically applied copper tape. The LCS resistance is also extremely stable during load cycling.

Jacket
The Okolene jacket on this cable is mechanically rugged, chemical, oil and moisture resistant.

Applications
Okoguard shielded Okolene Type MV-105 power cables are recommended for use as feeder circuits, in electric utility distribution circuits.

Type MV cables may be installed in wet or dry locations, indoors or outdoors (exposed to sunlight), in any raceway or underground duct, directly buried if installed in a system with a grounding conductor in close proximity that conforms with NEC Section 250-51, or messenger supported in industrial establishments and electric utilities.

Ampacities

(1) Ampacities are in accordance with Table 310-74 of the NEC for three single Type MV-105 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 105°C.

(2) Ampacities are in accordance with Table 310-82 of the NEC for an insulated single conductor directly buried with a conductor temperature rating of 105°C, ambient earth temperature of 20°C, 100% load factor, thermal resistance (RHO) of 90, with 7 1/2" spacing between the conductor center lines and 24" spacing between circuits.

(3) Ampacities are in accordance with Table 310-78 of the NEC for three single conductors or triplexed cable in one underground raceway, three feet deep with a conductor temperature of 105°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 installation in duct banks, multiple point grounded shields, 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 to cable O.D. should be checked to avoid possible jamming.
