Specific Use Cases of 750-750-750-500 URD

This cable is designed for high-load secondary distribution where 750 MCM conductors are required.

• It distributes secondary power from transformers to service meters in urban grids and industrial parks.
• It supplies underground power to commercial and industrial facilities that require high-capacity electrical distribution.
• It provides power to residential developments where underground service is necessary.
• It is used for buried power vaults and substation connections.
• It supports underground power in municipal infrastructure, renewable energy installations, mining operations, and military facilities.
• It is also used in underground data centers, disaster recovery power systems, and temporary high-power installations for large-scale events.

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.
