Product Overview
The Primary URD 5kV-46kV Copper Wire Shield Cable is a robust, medium-to-high voltage underground residential distribution (URD) cable engineered for industrial, commercial, and utility power systems. Designed to handle line-to-ground fault currents, this cable features a copper wire shield, thermoset EPR insulation, and UV-resistant jacketing, ensuring reliability in underground, duct, or direct burial installations. Compliant with UL, ICEA, and AEIC standards, it delivers superior electrical performance, moisture resistance, and thermal stability for critical power networks.
