8-8 BARD DUPLEX ALUMINUM CONDUCTOR UNDERGROUND DIRECT BURIAL 600V URD

Allowable Ampacity for 8-8 Bard Duplex Aluminum Conductor 600V URD Underground Direct Burial : 70 Amps

Allowable Ampacity for 8-8 Bard Duplex Aluminum Conductor 600V URD in duct: 55 Amps

Applications:

The 8-8 Bard Duplex Aluminum URD Cable is designed for single-phase underground power distribution in residential and light commercial applications. It is 600V-rated, suitable for direct burial or duct installation, and built for wet and dry conditions with a 90°C maximum operating temperature.

This duplex cable, with one phase conductor and one neutral, is used for overhead-to-underground service drops and secondary power distribution where compact and durable wiring is needed.

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 its two conductors coupled together and surface printing helps in identification of the conductors. The color for the neutral conductor is always yellow stripped.

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.
