Insulation
Okoguard is Okonite's registered trade name for its exclusive
ethylene-propylene (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.
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.
