250 MCM Hofstra Single Aluminum Conductor Underground Direct Burial 600V URD

Allowable Ampacity for 250 Hofstra Single Aluminum Conductor Underground Direct Burial 600V URD: 320 Amps

Applications:

This single aluminum conductor 600 V URD cable is used for primary and secondary underground power distribution in utility, commercial, and industrial settings. It is designed for direct burial or installation in ducts, ensuring efficient power delivery in wet and dry environments with a maximum operating temperature of 90°C. Its high ampacity makes it suitable for substations, commercial buildings, and renewable energy projects.

Specific Use Cases of 250 MCM Single URD:

• Primary and secondary power distribution in utility grids
• Feeder cables for commercial and industrial facilities
• Substation power connections for high-load distribution
• Underground transmission lines for municipal networks
• Grounding and neutral conductor applications in electrical systems
• Power transmission for renewable energy sources, including solar and wind farms
• Backup power supply for critical infrastructure like hospitals and data centers
• Temporary high-load power distribution for construction and industrial projects

Construction

Conductors:

This is an aluminum conductor cable. The conductor is designed in two forms: either concentric strand or compressed. The stranded type tends to be more flexible compared to the compressed series of aluminum conductors. The 1350-H19 series of compressed aluminum conductors are suitable for applications where flexibility is overlooked and cable rigidity is guaranteed.

Insulation:

Aluminum 600V URD cable has black resistant cross-linked polyethylene (XLP) insulation. The conductors are normally cabled together with XLP insulated aluminum ground or bare copper ground and covered with reinforced binder tape. XLP insulation is tough and resistant to impact, abrasion, chemicals, acids, oils, industrial solvents, and changes in weather.
