When it comes to reliable power distribution in commercial and industrial settings, UL-certified XHHW-2 Wire stands out as a top choice. But what exactly is XHHW-2 Wire, and how does it differ from the standard XHHW Wire? In this guide, we’ll explore its applications, advantages, and key differences to help you make an informed decision for your next electrical project.
What is XHHW-2 Wire?
XHHW-2 Wire (Cross-Linked High Heat Water-Resistant – 2) is a high-performance electrical wire designed for demanding environments. It is UL-listed (Underwriters Laboratories) and NEC (National Electrical Code) compliant, making it a trusted choice for power distribution in:
- Commercial buildings
- Industrial facilities
- Data centers
- Outdoor & underground installations
Key Features of XHHW-2 Wire:
✔ Cross-linked insulation – Enhances heat resistance & durability
✔ High-temperature rating (90°C in wet/dry conditions, 125°C in dry only)
✔ Water-resistant – Suitable for direct burial & wet locations
✔ UL-certified for safety & performance
✔ Available in multiple conductor sizes (AWG) & colors
Common Applications of XHHW-2 Wire
Due to its durability and safety features, XHHW-2 Wire is widely used in:
- Power Distribution Systems – Feeding motors, panels, and machinery
- Commercial & Industrial Buildings – Wiring for lighting, HVAC, and appliances
- Outdoor & Underground Installations – Resistant to moisture & temperature extremes
- Data Centers & Telecom Facilities – Reliable power for critical infrastructure
- Renewable Energy Projects – Solar & wind farm installations
Whether you need a wire for high-heat environments or wet locations, XHHW-2 Wire ensures long-lasting performance and safety.
What’s the Difference Between XHHW Wire and XHHW-2 Wire?
Many electricians and contractors wonder: ”Is XHHW-2 the same as XHHW Wire?” The answer is no—while they share some similarities, XHHW-2 has key upgrades that make it more robust.
| Feature | XHHW Wire | XHHW-2 Wire |
|---|---|---|
| Insulation Type | Thermoplastic (PVC) | Cross-linked Polyethylene (XLPE) |
| Temperature Rating | 75°C (wet/dry) | 90°C (wet/dry), 125°C (dry only) |
| Durability | Good, but less heat-resistant | Higher heat & abrasion resistance |
| Installation Flexibility | More flexible | Slightly thicker, but still flexible |
| Best For | Standard indoor/outdoor use | High-heat, wet, or demanding environments |
Why Choose XHHW-2 Over XHHW?
- Better heat resistance (ideal for high-load applications)
- Superior moisture & chemical resistance (great for underground/户外 use)
- Longer lifespan due to cross-linked insulation
