“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 4/0 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 90C.

• 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.
