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 6 mil copper longitudinal corrugated Okobon shield is applied over the extruded semiconducting insulation screen with a sealed overlap to make the cable core impervious to moisture penetration. The tape is copolymer coated to provide a bond at the overlap and to the outer jacket. This construction provides a substantially lower shield resistance compared to a tight helically ap- plied copper tape. The tape shield resistance is also extremely stable for the life of the cable.
Jacket
The Okolene® jacket on this cable is a polyethylene compound which is mechanically rugged; oil and moisture resistant. The outer jacket is firmly bonded to the corrugated copper shield for a moisture barrier.
