Insulation
Okoguard is Okonite's registered trade name for its exclusive ethylene-propylene rubber (EPR) base, 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.

Assembly
The Type MV-90 conductors are assembled with fillers and a binder tape into a round core. A bare stranded copper grounding conductor(s), located in the outer interstices, is provided for grounding. A continuously corrugated welded aluminum sheath C-L-X encases the cable core. The C-L-X sheath is protected with a low temperature yellow Okoseal^Ž( (PVC) jacket. The impervious, continuous, corrugated aluminum C-L-X sheath provides complete protection against moisture, liquids and gases in addition to its excellent mechanical strength. Also, the aluminum C-L-X sheath has adequate ampacity capability to be used as a grounding conductor. The overall Okoseal (PVC) jacket allows the cable to be direct buried in the ground, embedded in concrete or areas subjected to a corrosive atmosphere.

Applications
C-L-X 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. C-L-X power cables may be installed in both exposed and concealed work, wet and dry locations, 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. C-L-X power cables are also approved for Classes I, II and III. Divisions 1 and 2 and Class I, Zones 1 and 2 hazardous locations - NEC Articles 501, 502 and 503 and 505.
2.4 kV Non-Shielded cables discharge normally in service when spacing between phases is non-uniform or when phases are in close proximity to a grounded surface.
