500-500-350 Rider Triplex Aluminum Conductor Underground Direct Burial 600V URD

Allowable Ampacity for 500-500-350 Rider Triplex Aluminum Conductor 600V URD direct burial: 495 Amps

Allowable Ampacity for 500-500-350 Rider Triplex Aluminum Conductor 600V URD in duct: 395 Amps

Applications:

The 500-500-350 Rider Triplex Aluminum URD Cable is designed for secondary power distribution in underground electrical systems. It is 600V-rated and suitable for direct burial or installation in ducts. With aluminum conductors and XLPE insulation, this cable is moisture-resistant, heat-resistant, and durable for outdoor use.

With a maximum operating temperature of 90°C, it performs reliably in both wet and dry environments. The triplex configuration, consisting of two phase conductors and one neutral, makes it ideal for single-phase power distribution in utility and commercial applications.

Specific Use Cases of 500-500-350 URD

This cable supports high-load single-phase secondary distribution, delivering two 500 MCM phase conductors with a 350 MCM neutral for residential, agricultural, and light commercial applications.

• It distributes single-phase power from transformers to service meters in large residential developments and rural properties.
• It supplies underground power to farm buildings, irrigation systems, and agricultural facilities.
• It provides electricity to single-family homes, small apartment complexes, and mobile home parks.
• It is used in street lighting circuits and municipal power distribution.
• It connects distributed energy resources, such as residential solar and battery storage systems.
• It supports temporary power for construction sites, event venues, and emergency backup systems.

Construction

Conductors:

Aluminum conductors used for this cable are designed in either concentric strand or in compressed series. The advantage with a compressed conductor is the reduced bulkiness. Compressed conductors are also stronger and tougher; the stranded conductors are highly flexible and tend to have lower electrical resistance. Stranded conductors therefore reduce power loss and are also easier to use in applications where flexibility is vital. Aluminum 600 V URD cable has three aluminum conductors.

Insulation:

Versatile insulation system made of cross linked black polyethylene material helps to secure the cable conductors. This insulation is water tight, repulsive to corrosive substances, resistant to oil, heat and flame. Cross linking a polyethylene helps to achieve an excellent strength that makes the material suitable for covering this cable used in harsh conditions like direct burial installation.
