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.

What is XHHW wire?
XHHW wire is a type of electrical wire that is commonly used for building wiring and electrical installations. It is made with cross-linked polyethylene insulation, which provides excellent thermal and electrical properties. This wire is known for its durability, high-temperature resistance, and ability to resist moisture and abrasion. It is suitable for use in both indoor and outdoor applications and can be used in conduit or as direct burial wire. XHHW wire is available in either aluminum or copper wiring and in a range of sizes and colors to meet your specific electrical needs.
What are the differences between copper and aluminum XHHW wire?
It is important to understand the differences between copper and aluminum XHHW wire and their suitable applications. Copper wiring is considerably heavier than its counterpart, aluminum wire. However, copper is more conductive, making it a more effective and expensive solution. Aluminum, on the other hand, is much lighter than copper. However, with XHHW wire, this comes at a cost, as aluminum is less conductive than copper. While both forms of wiring offer considerable flexibility, it is critical to ensure that the wiring selected is the one most suitable to your installation requirements. Furthermore, in some localities, aluminum wiring may not be approved whereas copper wiring may be. Therefore, it is crucial when selecting the correct cabling to verify that the wiring selected meets any applicable standards or legal codes applicable to your application.
