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

"Industrial-scale primary power distribution—engineered with tree-retardant XLPE and dual-layer water blocking for maximum grid stability in ultra-high-load 35kV underground circuits."

Why Utilities Specify the 600 MCM 35kV URD

The 600 MCM 35kV URD cable is a specialized primary conductor engineered for applications where maximum ampacity is the priority. This gauge is a common choice for heavy industrial feeders and high-capacity utility interconnects that require more current density than the standard 500 MCM series can provide.

• Dual-Layer Water Block Protection: Moisture protection is critical for high-load conductors. This cable features a water-blocking compound within the conductor strands and water-swellable agents in the neutral layer, providing a complete longitudinal moisture seal to prevent "water treeing" over decades of service.

• Tree-Retardant XLPE (TR-XLPE): The 345-mil insulation wall is comprised of premium TR-XLPE. This material is chemically engineered to resist the electrochemical stressors that cause microscopic cracks in standard insulation, ensuring the cable survives in saturated or chemically active soil.

• 1/3 Concentric Neutral: Featuring 19 x #12 AWG (or equivalent conductivity) annealed bare copper wires, the 1/3 neutral configuration provides a high-capacity ground-fault path and excellent electrical stress control for ultra-high-load systems.

• Compact Stranded 1350-H19 Aluminum: The 600 kcmil aluminum core is compact-stranded to reduce the overall diameter and air gaps, allowing this high-capacity cable to be pulled through standard 5" or 6" primary duct banks.

Common 35kV Applications

• Major Industrial Interconnects: Providing 35kV primary service to large-scale refineries, steel mills, and heavy manufacturing campuses.

• High-Capacity Utility Hubs: Connecting primary substations to major localized distribution nodes in high-demand urban areas.

• Renewable Energy Infrastructure: Serving as a primary collector cable for the highest-capacity wind farms and solar arrays.

Technical Specifications

ENGINEERING OVERVIEW: 600 MCM HIGH CAPACITY DISTRIBUTION The 600 MCM 35kV URD cable is optimized for primary distribution applications requiring extreme current density and environmental resilience. With a robust nominal outer diameter of approximately 2.13", this cable is built for heavy-duty performance in primary ducts or direct burial 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: 600 MCM (600 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: 12 x #8 AWG Annealed bare copper wires (1/3 neutral conductivity).

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