When designing cost-effective power distribution systems for commercial and industrial projects, Aluminum Alloy XHHW Wire has become the top choice for feeder and branch circuit wiring. Among all aluminum building cables, the AA-8000 Aluminum Alloy Building Wire stands out for its stable electrical performance and outstanding mechanical durability. The Type XHHW-2 variant earns extra popularity as a reliable Wet Location Aluminum XHHW-2 Wire, with widely popular gauges including 3/0 AWG Aluminum XHHW-2 Wire for heavy-load power runs.
Traditional pure aluminum cables often suffer from creep deformation and loose connections after long-term operation. The AA8000 alloy formula solves this pain point perfectly, making XHHW/XHHW-2 aluminum wire ideal for conduit, cable tray, underground and multi-building power distribution projects across North America, the Philippines and Latin America.
1. Core Construction: AA-8000 Alloy Conductor
The whole cable is built around compact Class B stranded AA-8000 series aluminum alloy conductor, strictly manufactured according to ASTM B800 and ASTM B836 standards.
Anti-creep performance: Greatly reduces thermal expansion and contraction. Terminal joints stay tight after repeated heating and cooling, avoiding overheating and fire risks that are common with ordinary aluminum wire.
Stable conductivity: Balances high ampacity and lightweight structure, cutting total material cost by nearly 40% compared with copper building wire.
Flexible stranded structure: Easier to pull through long conduits and bend around building corners without conductor breakage.
The insulation layer uses cross-linked polyethylene (XLPE), which gives XHHW wire excellent resistance against moisture, oil, abrasion and UV sunlight exposure. The XHHW grade works for dry locations, while XHHW-2 is rated 90°C for both wet and dry environments, fully complying with NEC wiring requirements.
2. Key Advantages of AA8000 Aluminum XHHW/XHHW-2 Wire
① Dual wet & dry location rating
As a professional Wet Location Aluminum XHHW-2 Wire, this cable carries a 90°C temperature rating in both dry indoor areas and damp underground, basement or direct-buried environments. It works reliably in high-humidity tropical regions without extra waterproof wrapping.
② Lower total project budget
AA-8000 aluminum alloy is far lighter and more economical than copper. For long-distance feeder circuits, you can cut raw material expense significantly while maintaining enough current-carrying capacity. Sizes like 3/0 AWG Aluminum XHHW-2 Wire are frequently selected for main branch feeders of shopping malls, factories and multi-unit residential buildings.
③ Long service life for distribution circuits
XLPE insulation resists aging, chemical corrosion and heat degradation. Paired with the anti-creep AA-8000 alloy core, the wire can run continuously for 30+ years with minimal maintenance, perfect for permanent feeder and branch circuit installations.
④ Easy installation in raceways
The smooth solid XLPE jacket allows friction-free pulling through PVC and metal conduits. No extra lubricant is required for long vertical risers and horizontal tray wiring, speeding up on-site construction progress.
3. Main Applications: Feeders and Branch Circuits
This AA8000 Aluminum XHHW/XHHW-2 Wire is strictly engineered for NEC-specified power distribution circuits:
Main Feeder Circuits: Transmitting power from main switchgear to subpanels in industrial plants, commercial plazas and multi-story buildings. Sizes such as 3/0 AWG Aluminum XHHW-2 Wire are widely used for medium-to-heavy feeder runs.
Branch Circuit Wiring: Distributing power to lighting, HVAC, production machinery and electrical panels across different building zones.
Conduit & cable tray installation: Indoor raceway wiring, overhead cable tray runs.
Underground & direct burial: The XHHW-2 wet-location model fits damp trenches and buried conduit projects without additional sheathing.
Multi-unit residential construction: Townhouse and condominium power distribution systems where cost control is prioritized.
All products are UL 44 listed, fully compliant with North American and Philippine import standards for building electrical wire.
4. Popular Size Selection: 3/0 AWG Aluminum XHHW-2 Wire
Among all AWG options, 3/0 AWG Aluminum XHHW-2 Wire remains the best-selling gauge for mid-sized feeder and heavy branch circuits.
Ampacity meets most medium industrial and commercial main branch requirements
Compact stranded AA-8000 conductor keeps the outer diameter reasonable for standard conduit
XLPE wet-rated insulation works equally well indoors and underground
Available in black sunlight-resistant jacket, with 500FT standard spool packing for bulk wholesale orders.
We also supply a full AWG range from 2 AWG up to 1000 MCM, solid and compact stranded, XHHW dry-rated and XHHW-2 wet-rated versions as bulk factory OEM supply.
