What Is XHHW 2 Wire?

XHHW-2 wire is a type of electrical wire that is widely used for power distribution and transmission in various industrial, commercial, and residential settings. The acronym "XHHW" stands for Cross-Linked High Heat Water-resistant, and the "-2" denotes the second level of insulation. This wire is constructed to withstand high temperatures, making it a reliable choice for demanding electrical applications.

XHHW-2 wire is typically composed of a solid or stranded copper conductor, a cross-linked polyethylene (XLPE) insulation, and a durable thermoplastic or cross-linked polyethylene jacket. This combination of materials provides the wire with exceptional thermal and mechanical properties.

 

Heat Resistance: One of the key characteristics of XHHW-2 wire is its exceptional heat resistance. It can operate at temperatures up to 90°C (194°F) in dry conditions, and 75°C (167°F) in wet conditions, making it suitable for both indoor and outdoor applications.

 

Chemical Resistance: The XLPE insulation of XHHW-2 wire provides it with a high degree of resistance to various chemicals, oils, and solvents. This makes it an excellent choice for installations where exposure to corrosive substances is likely.

 

Moisture Resistance: XHHW-2 wire is designed to repel moisture, making it ideal for environments where dampness or water exposure is a concern.

 

Abrasion Resistance: The robust jacket material ensures that XHHW-2 wire can withstand abrasion, protecting it from physical damage during installation and throughout its lifespan.

 

Flexibility: Depending on the specific application, XHHW-2 wire can be found in both solid and stranded configurations, providing flexibility in installation.

 

XHHW-2 wire finds its use in a wide array of applications, including:

 

Commercial Buildings: It is commonly used in commercial structures for wiring electrical panels, lighting, and power distribution systems.

 

Industrial Facilities: XHHW-2 wire is prevalent in industrial settings, where it is employed for heavy-duty applications such as motors, machinery, and control circuits.

 

Residential Construction: In residential buildings, XHHW-2 wire may be used for branch circuits, service entrances, and other applications where durability and heat resistance are essential.

 

Outdoor Installations: Due to its resistance to moisture and UV rays, XHHW-2 wire is suitable for outdoor installations like underground conduit systems and direct burial applications.

 

XHHW-2 wire is a versatile and reliable component in electrical systems, renowned for its heat resistance, chemical resilience, and durability. Its ability to thrive in demanding environments makes it a popular choice in a wide range of applications, from residential homes to heavy industrial settings.

 

When selecting wiring for your projects, considering the specific requirements and conditions is crucial. XHHW-2 wire offers a compelling solution for applications where durability, heat resistance, and chemical tolerance are paramount. By understanding its composition and benefits, you can make informed decisions about incorporating XHHW-2 wire into your electrical installations.
