Insulation
Okoguard 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 Okoseal (PVC) jacket supplied with this cable is mechanically rugged and
has excellent resistance to oil and most chemicals.
Applications
Okoguard shielded Okoseal Type MV-105 power cables are recommended 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.
