What is the primary use of XHHW conductors?

The primary use of XHHW conductors is indeed for outdoor installations. XHHW, which stands for cross-linked polyethylene high heat-resistant water-resistant, is specifically designed to withstand harsh environmental conditions, including exposure to moisture and temperature variations. This makes XHHW conductors particularly suitable for outdoor settings where they may be exposed to rain, snow, and varying temperatures without compromising their integrity or performance.

In addition, XHHW conductors are also rated for use in wet and dry locations, which contributes to their suitability for outdoor applications. The material properties of XHHW allow it to function effectively in applications such as underground feeder lines, service entrances, and other outdoor electrical systems requiring a durable and reliable connection.
