Okonite Loxarmor® Type MV-90 or MC 2.4kV Okoguard® Nonshielded Power Cable 3 Okopact® (Compact Stranded) Copper Conductors/90°C Rating 100% and 133% Insulation Level

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 dielectric. 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.

Assembly
The Type MV-90 conductors are assembled with fillers and a binder tape overall. One bare stranded copper grounding conductor is placed in one of the outer interstices. The interlocked armor provides good mechanical strength. For direct burial, embedment in concrete or for areas subjected to corrosive atmospheres, the Loxarmor is protected with a yellow Okoseal^® (PVC) jacket.

Applications
Loxarmor power cables are recommended as an economical alternate to a wire in conduit system. They are designed specifically for use on feeders and branch circuits in industrial power distribution systems.

Loxarmor power cables may be installed in both exposed and concealed work, wet and dry location, direct burial in the earth, or embedded in concrete. They may be installed on metal racks, troughs, in cable trays or secured to supports not greater than 6 feet apart. Loxarmor power cables are also approved for Classes I and II, Division 2 and Class III, Divisions 1 and 2, hazardous locations - NEC Articles 501, 502 and 503.
