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.
Shield
A 5 mil copper longitudinal corrugated shield (LCS) is applied over the extruded semiconducting insulation screen.The LCS resistance is also extremely stable during load cycling
Jacket
The Okolon TS-CPE jacket on this cable is a vulcanized chloronated polyethylene base compound which is mechanically rugged, flame, radiation, and oil resistant.
Applications
Okoguard shielded Okolon TS-CPE 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.
