Okoguard Reduced Diameter Duct Cables provide maximum ampacity in existing duct installations.
Okoguard is Okonite's registered trade name for its exclusive ethylene-propylene base, thermosetting compound, whose optimum balance of electrical and physical properties is unequaled in other solid dielectrics. The clean red color of Okoguard is the result of an evolutionary development in ethylene-propylene rubber compounding to gain greater dependability of the electrical characteristics.
Over the insulation, a semiconducting ethylene-propylene layer is extruded, providing an all EPR system.
Copper flat straps are uniformly spaced around the semiconducting insulation EPR screen. The specially formulated jacket provides protection against mechanical damage and corrosion.
