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

Applications
Okoguard shielded Okolon Type MV-105 power cables are recommended for use as
feeder circuits in electric utility generating stations, for distribution
circuits, and for feeders or branch circuits in industrial and commercial
installations. 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 250.4(A)(5), or messenger
supported in industrial establishments and electric utilities. Sizes 1/0 AWG
and larger may also be installed in cable tray.

Aluminum
Conductors
(1) Aluminum conductors are available on special order. To order aluminum
conductors, change the first three digits of the catalog number from 114 to
134 and 115 to 135, respectively.Ampacities
(2) Ampacities are in accordance with Table 310.73 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.
(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 105°C, 100% Load Factor, an ambient
earth temperature of 20°C, and thermal resistance (RHO) of 90.
(4) Ampacities based on single Type MV-105 conductors, or single
conductors twisted together (triplexed, quadruplexed, etc.), size1/0 AWG and
larger, installed in uncovered cable tray in accordance with Section 392.13
of the NEC at an ambient temperature of 40°C and a conductor temperature
rating of 105°C. In accordance with NEC Section 392.13(b), the ampacities
are 75% of the values given in NEC Table 310.69 (copper conductors). Where
the cable tray is covered for more than six feet with solid unventilated
covers, the ampacities shall not exceed 93% of the values shown above.
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.
(5) Recommended size of rigid or nonmetallic conduit for three conductors
based on 40% maximum fill.
*The jam ratio conduit l.D. to cable O.D. should be checked to avoid possible jamming.
