Allowable Ampacity for 163-23-4240 250 MCM 1C 37Strand Aluminum Shield Full Neutral 133% EPR Concentric BC PE Okoguard URO-J 25KV URD Cable:100 Amps

About:

The " 163-23-4240 250 MCM1C 37Strand Aluminum Shield Full Neutral 133% EPR Concentric BC PE Okoguard URO-J 25KV URD Cable" is designed for underground power distribution with high voltage capability. It features a single conductor, aluminum shielding, full neutral copper strands, and is insulated with 133% Ethylene Propylene Rubber (EPR) for excellent electrical properties, covered by a durable polyethylene jacket.

Also Known As:

• 250 MCM Single Conductor URD Cable
• High Voltage EPR Insulated URD Cable
• 25KV Aluminum Shielded URD Cable

Application:

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

Standards:

• ASTM standards for material properties and performance.
• ICEA standards for underground residential distribution cables.
• ANSI specifications for safety and quality in high-voltage applications.
• Possible additional certifications for environmental resistance and fire safety, depending on the manufacturer's specifications.

Construction:

• Central Conductor: Aluminum per ASTM B609, Class B stranded per B-231.
• Filled Strand: Water swellable agent meets or exceeds ICEA T-31-610 water penetration resistance and ANSI/NEMA Class A connectorability requirements.
• 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 ethylene-propylene rubber meets or exceeds the requirements of ICEA S-94-649, AEIC CS8, and CSA C68.5.
• Concentric Conductor: Bare copper concentric wires helically applied.
• Jacket: Black Okolene with 3 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.
• Meets RUS 1728.204 for cables with filled strand or solid conductor and 133% insulation level.
