Allowable Ampacity for 500-500-300 MCM Holyoke Triplex Aluminum Conductor 600V URD direct burial: 495 Amps
Allowable Ampacity for 500-500-300 MCM Holyoke Triplex Aluminum Conductor 600V URD in duct: 395 Amps
The Aluminum 600V URD is designed to serve in the secondary distribution circuits for power. In these secondary circuits, the electrical cable is installed in duct or direct burial applications. Due to its versatility, conductor strength, and insulation integrity, it works well for these outdoor applications. It is also used in wet and dry places since the electrical cable has a maximum operating temperature of 90°C. The triplex wire for sale is also designed to provide an option of pre-pulling into ducts.

J-C- 30B Federal Specification
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.
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.
