URD Cable XLPE Underground (Direct Burial)

Designed for distributing power from a transformer to individual homes or buildings in underground electrical distribution systems. URD cables are commonly used in residential areas, commercial developments, and industrial complexes.

Application

URD cables are designed to be buried directly in the ground, providing a safe and reliable method for delivering power to homes and buildings. These cables are insulated and protected to withstand the environmental conditions encountered underground, including moisture, soil acidity, and physical stresses. It is commonly used to distribute electricity from transformers to residential areas and other low-voltage applications.

Construction

Conductors
Class B compressed concentric lay stranded 1350 aluminum alloy
Insulation
Phase conductors in black thermoset cross-linked polyethylene (XLPE).
Neutral conductor in black thermoset cross-linked polyethylene (XLPE) identified by yellow striping or full yellow jacket.

Feature

Huadong’s URD cables offer several advantages: reliability, reduced power loss, improved safety, and lower maintenance.

Type

Single Aluminum Conductor Underground Direct Burial 1350 Series
Duplex Aluminum Conductor Underground Direct Burial 1350 Series
Triplex Aluminum Conductor Underground Direct Burial 1350 Series
Quadruplex Aluminum Conductor Underground Direct Burial 1350 Series
