"Maximum reliability for residential power loops—featuring tree-retardant XLPE and a dual-layer water block to ensure 35kV grid stability in high-moisture underground environments."
The 2/0 35kV URD cable is the industry standard for primary residential and commercial underground distribution. It provides the ideal balance between high ampacity and physical flexibility, making it a favorite for regional utility contractors.
Dual-Layer Water Block Protection: Moisture is often the leading cause of medium-voltage failure. This cable features a dual water block preventing longitudinal water travel even if the jacket is damaged.
Tree-Retardant XLPE (TR-XLPE): Engineered with 345 mils of specialized TR-XLPE insulation, this cable is built to resist the "water treeing" that can occur in underground environments, dramatically extending the service life of the circuit.
1/3 Concentric Neutral: Featuring 7 x #14 AWG annealed bare copper wires, the 1/3 neutral design offers optimized grounding for balanced three-phase systems while reducing overall weight and material cost.
Hard-Drawn 1350-H19 Aluminum: High-strength aluminum conductors ensure the cable maintains its integrity during high-tension pulls through long conduit runs.
Primary Residential Loops: Ideal for distributing primary power to multiple transformer stations within a neighborhood.
Commercial Perimeter Power: Providing stable 35kV service to office complexes and shopping centers.
Substation Exit Cables: Often used for the first stage of distribution exiting a small-to-medium utility substation.
ENGINEERING OVERVIEW: 2/0 AWG PRIMARY DISTRIBUTION The 2/0 35kV URD cable is optimized for primary underground distribution where increased current capacity is required relative to standard lateral runs. Featuring a 1.59" nominal outer diameter and a robust 1350-H19 aluminum core, this cable is designed for direct burial or duct installation in environments subject to high soil acidity and moisture.
APPLICATION: Aluminum Conductor MV-105 35kV water-blocked URD cable is primarily used for primary underground power distribution in residential and commercial applications. Suitable for use in wet or dry locations.
CONDUCTORS: 2/0 Compact or compressed aluminum 1350-H19 in Class B stranding.
CONDUCTOR WATER BLOCK: Interstitial spaces between strands are filled with a water-blocking compound to prevent moisture migration.
INSULATION: TR-XLPE (Tree-Retardant Cross-Linked Polyethylene) in 100% insulation level (345 Mils).
CONCENTRIC NEUTRAL: 7 x #14 AWG Annealed bare copper wires (1/3 neutral conductivity).
CONCENTRIC NEUTRAL WATER BLOCK:
Semi-conducting water swellable tape over the insulation shield or water-swellable powder between the concentric neutral strands
JACKET: Sunlight resistant XLPE, black with three red stripes.

Under standard conditions (90°C conductor, 20°C earth temperature, and 90 RHO soil resistivity), the ampacity for 2/0 AWG Aluminum is approximately 195 Amps when direct buried and 165 Amps when installed in an underground duct.
⚠️ CUSTOMER WARNING: Actual ampacity must be calculated based on your specific project conditions, including soil thermal resistivity (RHO), burial depth, duct bank configuration, and load factor per NEC Article 311. Consult a licensed electrical engineer for final system design.
The approximate outside diameter for this cable is between 0.95 and 1.05 inches. For a single cable, a 2-inch conduit is standard. For a triplex installation (three cables twisted together), a 2.5-inch or 3-inch conduit is recommended. Using a 3-inch pipe provides ample clearance, which is especially important for 35kV cables to ensure the pulling tension does not damage the outer jacket or the concentric neutrals.
Even in smaller primary distribution sizes like 2/0, moisture remains the primary cause of cable failure. This cable uses swellable water-blocking agents within the conductor strands that expand instantly when they come into contact with water. This prevents moisture from traveling longitudinally through the cable. By blocking water migration, the cable is protected against "water treeing"—a phenomenon where moisture causes microscopic fractures in the 35kV insulation, eventually leading to a dielectric breakdown.
The 1/3 Neutral means the copper concentric wires provide a total cross-sectional area equal to one-third of the 2/0 aluminum phase conductor. This is the industry-standard balance for three-phase primary distribution. It provides a reliable grounding and fault current path while keeping the cable profile smaller and more flexible than a full-neutral cable. This smaller footprint makes 2/0 a popular choice for tapping into smaller transformers or sectionalizing cabinets.
To protect the high-voltage insulation and the semiconductive shielding layers from mechanical damage, you must adhere to the following limits:
