1/0 Aluminum Direct Burial Wire, Harvard URD

"Designed for 600V secondary power distribution, this single-conductor URD cable is built for performance. Featuring sunlight-resistant XLP insulation, it is rated for both direct burial and duct installations, providing a reliable, long-term solution for underground utility and sub-panel feeds."

Why Choose 1/0 AWG Aluminum URD?

This cable is the industry standard for secondary underground power feeds where independent phase management is required. Its 1350-H19 aluminum construction and XLP insulation ensure maximum durability against moisture and environmental stress.

• 600V Power Rating: Consistent performance in wet or dry locations up to 90°C.

• Direct Burial Rated: Specifically designed to be buried directly in the earth without protective conduit.

• Sunlight Resistant: XLP insulation prevents UV-driven degradation.

• Versatile Installation: Optimized for direct-trench or conduit/duct applications.

Common Applications

• Secondary Underground Distribution: Power feed from transformer to service entrance.

• Residential & Farm Power: Reliable high-capacity sub-panel feeds and outbuilding power.

• Underground Routing: Ideal for direct-trenching or pull-through conduit.

• Custom Phase Management: Because this is a single conductor, it is frequently used in custom underground layouts where the electrician needs to manage individual phases (for example, in complex commercial underground runs or when replacing a single damaged lead in an existing circuit).
