Allowable Ampacity for 140-23-8049 1250 MCM 1C Bare Copper Unshielded EPR Concentric 1/6 Neutral Okolene 445 46KV Okoguard URO-J Cable:100 Amps

About:

This cable model is part of the Okoguard line, specifically engineered for high-voltage (46 kV) applications. It features a bare copper conductor and is known for its robust construction and reliability in harsh environments.

Also Known As:

This specific model of cable might be commonly referred to in technical documentation or by professionals simply as “46KV Okoguard URO-J Cable” or “1250 MCM AWG Okoguard 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:

• IEEE 1202: Compliance for flame resistance in cable trays.
• IEEE 383: Testing for cable performance in harsh environments.
• ANSI/NEMA WC70/ICEA S-95-658: Specifications for power cables up to 46 kV.
• AEIC CS8: Guidelines for extruded dielectric shielded power cables.

Construction:

• Conductor: Uncoated copper sizes 4/0 AWG 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 per ASTM B609, compressed Class B strand per ASTM B231.
• Conductor Screen: Extruded semiconducting ethylene-propylene rubber meets or exceeds the requirements of ICEA S-94-649, AEIC CS8, and CSA C68.5.
• Insulation: Extruded Okoguard meets or ® exceeds the requirements of ICEA S-94-649, AEIC CS8, and CSA C68.5.
• Insulation Screen: Extruded semiconducting EPR insulation screen. Meets or exceeds electrical and physical requirements of ICEA S-94-649, AEIC CS8, and CSA C68.5.
• Concentric Conductor: Bare copper concentric neutral wires helically applied.
• Jacket: Black OKOLENE LLDPE with red ® extruded stripes. Meets or exceeds the requirements of ICEA S-94-649, AEIC CS8, and CSA C68.5 for polyethylene jackets.

Features:

• Triple tandem extruded, all EPR system.
• Okoguard cables meet or exceed ICEA standards.
