The 28kV Aluminum Conductor Underground Residential Distribution (URD) Cable is engineered for primary power distribution systems, particularly in underground utility and residential applications. Designed with 100% insulation level (0.280" wall thickness), it ensures reliable performance and dielectric strength in medium-voltage networks.
The cable features a TR-XLPE (Tree-Retardant Cross-linked Polyethylene) insulated aluminum conductor, surrounded by concentric neutral wires (full or one-third coverage), and a rugged LLDPE jacket with optional semi-conducting layer. This construction offers superior electrical performance, resistance to moisture ingress, mechanical durability, and flexibility for installation in ducts or direct burial.
| Conductor | Compact aluminum (per ASTM B231/B-609) |
| Insulation | TR-XLPE (Tree-Retardant XLPE), 90°C rated, 0.175" nominal thickness 100% insulation level per ICEA S-94-649 |
| Concentric Neutral Conductor | Concentric layer of aluminum wires Options: Full Neutral or One-Third Neutral coverage |
| Sheath | Black LLDPE (Linear Low-Density Polyethylene), UV-stabilized Optional: Three red stripes for identification or semi-conducting PE for additional shielding |
