Specific Use Cases of 250-250-250-3/0 URD

This cable is used for medium-load secondary distribution:

• It powers service meters from pad-mounted transformers in suburban and rural distribution networks.
• It supplies underground power to small commercial buildings, schools, and municipal facilities.
• It provides electricity to residential subdivisions and manufactured home communities.
• It is used in underground vaults and power distribution panels for municipal and industrial systems.
• It connects small renewable energy installations, such as solar panel arrays and wind turbines.
• It supports temporary power needs at construction sites and backup power for emergency systems.

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.
