Specific Use Cases of 500-500-500-350 Aluminum URD

This cable is designed for medium to high-load secondary distribution, where 500 MCM conductors provide the necessary ampacity for commercial, utility, and infrastructure applications.

• It distributes secondary power from transformers to service meters in urban grids and industrial zones.
• It supplies underground power to commercial buildings, industrial facilities, and municipal infrastructure.
• It provides power to residential subdivisions and mixed-use developments where underground service is necessary.
• It is used for buried power vaults and substation connections.
• It supports underground power in renewable energy systems, emergency backup grids, and construction site power.

Construction

Conductors:

Aluminum conductor used for this cable is either a concentric strand or compressed 1350-H19 series aluminum conductor. The conductors are cabled together, with surface printing for identification. The neutral conductor has a yellow stripe. 

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.
