XHHW-2 Aluminum Building Wire Manufacturer & Supplier in China

600V XLPE Insulated Aluminum Wire for Commercial and Industrial Power Distribution

Sitong Cable is a professional XHHW-2 Aluminum Building Wire manufacturer and supplier in China, providing high-quality 600V aluminum building wire with XLPE insulation for commercial, industrial, and electrical distribution applications.

Our Aluminum XHHW-2 Wire is manufactured with AA-8000 series aluminum alloy conductors and cross-linked polyethylene (XLPE) insulation, offering excellent electrical performance, moisture resistance, and long-term reliability.

Designed according to North American electrical requirements, XHHW-2 wire is widely used for feeders, branch circuits, conduit systems, underground raceways, and power distribution projects.

What Is XHHW-2 Aluminum Building Wire?

XHHW-2 Aluminum Building Wire is a thermoset-insulated electrical conductor mainly used in low-voltage power distribution systems.

The designation "XHHW-2" means:

• X – Cross-linked polyethylene (XLPE) insulation
• HH – High heat resistance
• W – Water-resistant
• -2 – 90°C temperature rating in both wet and dry locations

Compared with standard XHHW wire, XHHW-2 provides improved moisture resistance and maintains a 90°C operating temperature rating in wet environments, making it suitable for modern commercial and industrial electrical installations.

Construction of Aluminum XHHW-2 Wire

Aluminum Alloy Conductor

The conductor is manufactured using AA-8000 series aluminum alloy, which is specifically designed for building wire applications.

Key advantages:

• Lightweight compared with copper conductors
• Excellent electrical conductivity
• Good corrosion resistance
• Easy installation and transportation
• Cost-effective solution for large electrical feeders

XLPE Insulation

The conductor is insulated with high-quality cross-linked polyethylene (XLPE) material.

Features include:

• 90°C wet and dry temperature rating
• Excellent moisture resistance
• High insulation stability
• Superior electrical performance
• Long service life
