XHHW-2 Wire

(Showing 24 of 225)

XHHW-2 wire is a cross-linked, high heat and water-resistant building wire designed for demanding electrical installations. It uses copper or aluminum conductors with XLPE insulation that provides strong protection against heat, moisture, and abrasion. Rated 105°C in dry locations and 90°C in wet locations, it performs reliably in both indoor and outdoor environments.

Approved for conduit, raceways, and direct burial, XHHW-2 is a durable choice for residential, commercial, and industrial wiring where long-term insulation strength and consistent performance are required.

FAQs

XHHW-2 means cross-linked, high-heat, and water-resistant wire. The “-2” indicates it can handle higher voltage and better insulation performance, suitable for both dry and wet locations.

It’s used for conduit, raceways, and direct burial in residential, commercial, and industrial wiring. It’s ideal for feeders, branch circuits, and service conductors that need high durability.

XHHW-2 offers better heat resistance—rated 90°C in wet and 105°C in dry conditions—compared to standard XHHW, which handles only up to 75°C when wet. It’s the preferred option for most modern electrical installations.

It uses XLPE (cross-linked polyethylene) insulation, which resists heat, moisture, and chemicals. This makes it durable in tough environments and long-lasting in both indoor and outdoor wiring.

Yes. We stock both copper and aluminum options in a wide range of AWG sizes. You can filter by material on the category page to match your project needs.
