Nassau Bergen 1/0-1/0-1/0 Triplex, 110′ URD Direct Burial
This 110-foot URD triplex cable showcases a uniform conductor arrangement with a neutral of AWG 1/0. Designed for direct burial, it supports underground service installations with robust insulation suitable for outdoor environments. The compact assembly supports straightforward pulling and tension management during trench work. Optimum for residential trenching or feeder runs, the triple-conductor design helps simplify routing and splicing in constrained spaces.
Nassau Bergen 1/0-1/0-1/0 Triplex, 100′ URD Direct Burial
Priced for direct burial, this 100-foot triplex assembly uses AWG 1/0 conductors with a consistent neutral sizing. It is designed for URD distribution with emphasis on reliable insulation and outdoor durability. Installers should note the length options allow for flexible routing in medium-scale residential feeders or street-lighting feeds, with straightforward termination at suitable splice points.
Nassau Bergen 1/0-1/0-1/0 Triplex, 90′ URD Direct Burial
This 90-foot URD triplex cable delivers uniform 1/0 phase conductors with a 1/0 neutral configuration, optimized for direct burial. Its insulation and shielding are intended to resist moisture ingress and environmental exposure typical of underground service feeders. This length is particularly suitable for shorter residential feeder runs or service drops requiring compact looping and secure burial.
Nassau Brenau 375′ Triplex 1/0-1/0-2 Wire Direct Burial XLP USE
At 375 feet, this Brenau triplex bundle uses a 1/0 phase configuration with a 2-wire neutral, optimized for larger URD or direct burial projects where longer runs are required. The XLP USE insulation enhances resistance to harsh underground conditions. Weighing considerations include pulling tension and reel handling for long, uninterrupted installations across properties or corridors with few pull points.
Nassau Brenau 150′ Triplex 1/0-1/0-2 Wire Direct Burial XLP USE
This 150-foot Brenau triplex option provides a longer run for URD or buried service feeds, with a dual 1/0 phase configuration and a 2-wire neutral. XLP USE insulation supports underground resilience, while the longer length reduces the number of splices needed on extended routes. Suitable for mid-length residential or small commercial underground installations, it balances flexibility and durability.
Nassau Neritina 1/0-1/0-1/0 Triplex Overhead/Underground (ACSR) 200′
While this option includes an overhead-compatible designation (ACSR), it remains a 1/0-1/0-1/0 configuration suitable for versatile distribution needs, including some underground service scenarios. The 200-foot length supports longer service runs with the same AWG 1/0 conductors. Considerations include pole or trench routing and compatibility with existing hardware for aerial or buried applications.
Buying Guide
Key considerations when selecting 1/0 aluminum triplex cables include conductor size, insulation type, and installation environment. AURD (burial) and URD (underground residential distribution) cables must resist moisture, moisture-induced corrosion, and soil pressures. Insulation thickness and jacket materials influence pull strength, abrasion resistance, and long-term durability. The neutral size impacts fault tolerance and bending characteristics during installation.
- Application type: Confirm URD (underground residential) versus direct burial. URD cables are typically optimized for trenching and buried feeders, while direct burial cables emphasize moisture resistance and long-term stability in soil environments.
- Conductor configuration: Ensure the triplex arrangement matches the planned routing and splice requirements. The 1/0-1/0-1/0 setups provide consistent phase spacing, with neutral sizing influencing load balancing and fault isolation.
- Insulation and jacket: Look for XLP or equivalent insulation for underground resilience. Thicker insulation often correlates with better resistance to moisture and environmental stressors but may affect flexibility and pulling.
- Length and reels: Longer lengths reduce the number of splices but require careful handling during installation to prevent damage. Determine whether you need fixed-length reels or custom cut lengths.
- Mechanical properties: Pulling tension ratings, abrasion resistance, and jacket flexibility are critical for trench work, especially in rocky soils or narrow trenches.
- Pricing and availability: Consider lead times for longer reels and compatibility with existing hardware, such as connectors, terminations, and reels.
Comparisons and Perspectives
When evaluating similar 1/0 aluminum triplex cables, compare insulation type, maximum burial depth suitability, and the presence of any regional or application-specific certifications. For residential underground runs, shorter lengths with consistent phase and neutral sizing can simplify splicing and reduce install time. For longer feeders, longer reels reduce the number of joints, albeit with greater handling requirements during deployment. Fiber or additional shielding can be considered where there is a high risk of physical damage or moisture exposure.
