Mv Urd Cable

MV URD Cable: Definition and Technical Specifications

Medium Voltage (MV) Underground Residential Distribution (URD) cable is the primary infrastructure for underground power grids, connecting substations to residential and commercial transformers Wireamerica.

* Voltage Ratings: Standardized at 15kV, 25kV, and 35kV Wireamerica.

* Conductor: Predominantly 8000-Series Aluminum for its lightweight properties and cost-efficiency in underground pulls Wireamerica.

* Insulation: TR-XLPE (Tree-Retardant Cross-Linked Polyethylene) is standard to prevent moisture-induced degradation ("water trees") Wireamerica.

* Shielding: Features a concentric neutral layer of bare copper wires for grounding and fault current return Wireamerica.

* Insulation Levels: Available in 100% level (faults cleared <1 min) and 133% level (faults persistent up to 1 hr) Wireamerica.
