1000 MCM Aluminum URD Cable 35kV 100% Insulation | Water Block 1/3 Neutral

"The strong solution for high-density metropolitan power—engineered with tree-retardant XLPE and dual-layer water blocking for maximum 35kV reliability in critical infrastructure feeders."

Why Utilities Specify the 1000 MCM 35kV URD

The 1000 MCM 35kV URD cable is a premier primary conductor designed for the highest-capacity underground distribution systems. It is the preferred choice for engineers managing massive power requirements for data centers, hospital campuses, and major municipal infrastructure where power failure is not an option.

• Dual-Layer Water Block Protection: On a conductor of this magnitude, moisture ingress is the greatest threat to system longevity. This cable utilizes specialized water-blocking compounds in the conductor strands and water-swellable agents in the neutral layer to create a permanent longitudinal moisture seal.

• Tree-Retardant XLPE (TR-XLPE): Featuring a 345-mil insulation wall, the TR-XLPE is chemically formulated to inhibit the formation of "water trees," ensuring the cable remains electrically stable even under the extreme thermal stress of a 1,000 kcmil load.

• 1/3 Concentric Neutral: Featuring 20 x #10 AWG annealed bare copper wires, this configuration provides a massive grounded path for fault currents and superior electrical stress control for the highest-load utility systems.

• Stranded 1350-H19 Aluminum: The 1000 kcmil core provides maximum tensile strength while maintaining a profile that can typically be pulled through 5" or 6" primary duct banks.

Common 35kV Applications

• Data Center Primary Feeder: Providing the massive, reliable power required to sustain hyperscale cloud and enterprise data facilities.

• Critical Hospital Infrastructure: Ensuring stable 35kV primary service for large-scale medical campuses and trauma centers.

• Municipal Grid Arteries: Serving as the main underground "power highway" connecting major city substations to high-demand downtown districts.

Technical Specifications

ENGINEERING OVERVIEW: 1000 MCM CRITICAL INFRASTRUCTURE FEEDER The 1000 MCM 35kV URD cable is optimized for primary distribution applications requiring the highest available current density and environmental resilience. With a robust nominal outer diameter of approximately 2.43", this cable is engineered for durability in the most demanding direct burial or primary duct installations.

APPLICATION: Aluminum Conductor MV-105 35kV water-blocked URD cable is primarily used for primary underground power distribution. It is suitable for use in wet or dry locations, installed in underground ducts or via direct burial.

CONDUCTORS: 1000 MCM (1000 kcmil) Compact or compressed aluminum 1350-H19 in Class B stranding.

CONDUCTOR WATER BLOCK: Water block compound filled conductor or water swellable tape over the conductor.

INSULATION: TR-XLPE (Tree-Retardant Cross-Linked Polyethylene) in 100% insulation level (345 Mils).

CONCENTRIC NEUTRAL WATER BLOCK: Semi-conducting water-swellable tape over the insulation shield or water-swellable powder between the concentric neutral strands.

CONCENTRIC NEUTRAL: 20 x #10 AWG Annealed bare copper wires (1/3 neutral conductivity).

JACKET: Sunlight resistant XLPE, black with three red stripes for easy high-voltage phase identification.
