Collection: Aluminum URD Direct Burial Wire
Direct Burial Cable is an electrical wire designed to be buried underground without the need for additional protective covering. Aluminum is commonly used for overhead and direct burial lines due to its cost efficiency and performance over long distances.
Nassau Electrical Supply offers a wide range of aluminum overhead and URD (Underground Residential Distribution) cables, primarily made from aluminum 1350-H19, a high-purity alloy known for its excellent conductivity, strength, corrosion resistance, and flexibility.
These cables are typically concentric-lay-stranded conductors insulated with cross-linked polyethylene (XLPE) for protection against environmental factors like moisture, heat, chemicals, and UV exposure. Available in duplex, triplex, and quadruplex configurations, they support multiple circuits and are rated for up to 600 volts, suitable for overhead, direct burial, ducts, or cable tray installations.
