4/0 15kV Aluminum URD Cable 133% Insulation | Full Neutral

“The heavy-duty backbone for subdivision trunk linesengineered with 133% TR-XLPE insulation and water-blocked conductors for high-capacity underground primary distribution.”

Why Utilities Specify the 4/0 AWG 15kV 133% URD

The 4/0 AWG aluminum cable is the high-capacity standard for primary feeders and main trunk lines. By using a 133% insulation level (220 mils), it provides a superior safety margin against voltage surges compared to standard 100% rated cables.

• Water-Blocked Stranded Conductors: This cable features compressed concentric stranded 1350 series aluminum with interstitial spaces filled with a water-blocking compound. This stops longitudinal moisture migration if the cable’s integrity is ever compromised.

• 133% TR-XLPE Insulation: Naturally high dielectric strength Tree-Retardant XLPE insulation resists the formation of “water trees,” significantly extending the service life of underground infrastructure in wet environments.

• Full Concentric Neutral: Featuring 13 x #10 AWG solid bare copper wires, this 4/0 AWG cable provides a 100% neutral capacity, ensuring maximum grounding safety and return current capability for high-ampacity systems.

• Durable LLDPE Jacket: The black Linear Low-Density Polyethylene jacket is sunlight, abrasion, and heat resistant, marked with the NESC lightning bolt and sequential footage markings for easy field identification.

Common 4/0 AWG 15kV 133% Applications

• Subdivision Trunk Lines: The main “artery” routing 15kV power to various laterals within a housing development.

• Industrial Feeders: Providing reliable primary power to large manufacturing or commercial facilities.

• Three-Phase Utility Loops: Ideal for looped primary systems in municipal grids where 4/0 capacity is required to meet peak demand.
