161-23-3931 Okoguard URO 15kV Underground Primary Distribution Cable - 4/0 AWG - 1/3 Neutral
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.
An insulation screen of ethylene-propylene rubber is extruded over the insulation. The annealed bare copper wires are uniformly spaced around the insulation screen.
Okoguard URO cables provide excellent circuit longevity in underground residential distribution systems. They can be buried direct or installed in underground ducts or conduits.
