XHHW Wire – Buy Hook-Up & Building Wire Online in Copper or Aluminum

Looking to buy XHHW wire? We stock a full range of high-performance XHHW hook-up and building wire, available in copper or aluminum conductors and multiple gauge sizes. This 600V-rated wire is insulated with cross-linked polyethylene (XLPE), delivering superior resistance to heat, moisture, and abrasion. It's rated for up to 90°C in dry conditions and 75°C in wet conditions, making it an ideal choice for commercial and industrial electrical applications.

Unlike PVC-insulated wire, XHHW cable does not emit toxic smoke when exposed to flame and offers better flexibility and pull performance during installation. The durable thermoset insulation outperforms nylon coatings in both harsh and low-temperature environments, maintaining excellent electrical integrity over time.

Whether you're sourcing wire for conduit installations, panel wiring, or direct burial, our XHHW-2 wire meets key industry standards and is ready to ship in bulk. Choose the gauge, material, and length that fits your needs — and get fast turnaround from a trusted wire and cable supplier.
