About:

The Okoguard cable features a bare copper conductor and uses EPR for its insulation, providing excellent electrical properties and resistance to thermal degradation. The concentric neutral design involves neutral wires being concentrically laid over the insulation layer, offering additional security and fault tolerance. The Okolene URO-J is a specific jacketing material used for mechanical, chemical, and environmental protection of the cable.

Also Known As:

• Okoguard EPR Cable
• Bare Copper Concentric Neutral Cable
• Unshielded EPR Cable
• Okolene URO-J Jacketed Cable

Application:

• Okoguard URO-J cables provide maximum  circuit longevity in underground residential distribution systems. They can be buried direct or installed in underground ducts or conduits.

Standards:

• ANSI/NEMA WC 70: Power Cables Rated 2000 Volts or Less for the Distribution of Electrical Energy.
