Product Overview
XLPE/EPR Insulated URD Cable (MV-90 & MV-105) delivers reliable power distribution for industrial networks up to 35kV. Engineered with triple-extruded XLPE or EPR insulation, thermosetting semiconductor screens, and copper-wire shielding, this cable excels in direct burial, duct, and wet/dry installations. Ideal for substations, refineries, and utility networks requiring ANSI/ICEA compliance and 105°C operational resilience.
