Copper or Aluminium Conductor Medium Voltage URD Cable
Product Overview
High-Performance Medium Voltage URD Cable for Underground Distribution
This UL 1072-certified cable features XLPE insulation with aluminum or copper conductors, engineered for 5kV-35kV primary underground distribution. Exceeding ANSI/ICEA S94-649 and AEIC CS-8 standards, it delivers reliable performance in direct burial, duct installations, wet/dry locations, and sunlight-exposed environments. Operational temperatures support continuous 90°C, overload 130°C, and short-circuit 250°C conditions.
Product Advantages
-
Triple-Extruded Construction: Dry-cured XLPE insulation ensures superior dielectric strength and moisture resistance
-
Enhanced Safety: Concentric copper neutrals (uncoated/coated) provide fault current protection
-
Environmental Resilience: LLDPE jacket with red stripes offers UV/abrasion resistance and phase identification
-
Installation Flexibility: Available in triplex configuration for cost-efficient trenching
-
Custom Options: Strand-filled conductors, water-blocking tech, and PVC/semi-conducting jackets
-
Standards Compliance: Meets ASTM B-3/B-8/B-230/B-231 and UL 1072 safety requirements
Applications
-
Primary underground distribution (URD/ERP)
-
Direct earth burial (no conduit required)
-
Underground duct systems
-
Solar-exposed installations
-
Industrial power networks
