Product Information

Specification

About:

This cable typically consists of Ethylene Propylene Rubber (EPR) insulated conductors with a bare copper or aluminum shield. The EPR provides excellent dielectric and mechanical properties essential for handling high voltages, such as 69 kilovolts (KV). The outer jacket is made from Okoseal PVC (polyvinyl chloride), which offers good resistance to environmental factors like moisture, chemicals, and physical abrasion.

Also Known As:

• 69KV URD Cable
• EPR URD Cable
• High Voltage URD Cable
• Okoguard URD Cable

Application:

• Okoguard-Okolene 69kV cables are for use as primary circuits in electrical utility and industry applications where they provide maximum circuit security and economical installation. Rated 105°C for continuous operating temperature. Okoguard 69kV cables may be installed in wet or dry locations indoors or outdoors (exposed to sunlight) in underground ducts, conduits or direct burial.

Standards:

• ANSI/ICEA S-94-649 for concentric neutral cables
• ASTM standards for material properties
• AEIC CS8 for extruded dielectric cables

Construction:

• Conductors: Uncoated copper sizes 250 through 1000 kcmil are compact round
strand per ASTM B496. Uncoated copper sizes larger than 1000 kcmil are compressed Class B strand per ASTM B3 and ASTM B8. Aluminum conductors are compressed Class B strand per ASTM B231 & B609.
• Conductor Screen: Extruded semiconducting ethylene-propylene rubber meets or exceeds the requirements of ICEA S-108-720 and AEIC CS9.
• Insulation: Extruded Okoguard meets or exceeds the requirements of ICEA S-108-
720 and AEIC CS9.
• Insulation Screen: Extruded semiconducting EPR insulation screen. Meets or exceeds electrical and physical requirements of ICEA S-108-720 and AEIC CS9. Available with strippable or bonded screen.
• Concentric Conductor: Bare copper concentric neutral wires helically applied sized 1/3, 1/6 or 1/12 or based on fault current requirements. Optional shields include a combination of copper tape and wires or a longitudinal corrugated copper tape. A C-L-X armor covering is also ® available.
• Jacket: Black OKOLENE LLDPE with red extruded stripes that meets and exceeds
the requirements of ICEA S-108-720 and AEIC CS9. Optional jackets include FRPVC OKOSEAL , OKOLON TP-CPE , ® ® OKOCLEAR TP (TPPO-low smoke zero ® halogen) and when specified, a thermoset jacket or semi-conducting outer layer

Features:

• Triple tandem extruded, all EPR system.

qualified for operation at 105°C continuous and 140°C emergency operating
temperature.
• 250°C short circuit rating.
• Excellent corona resistance.
• Low dielectric constant and power factor.
• Screens are clean stripping.
• Exceptional resistance to "treeing".
• Moisture resistant.
• Excellent resistance to most chemicals.
