THHN

THHN wire is characterized by its thermoplastic insulation, which provides resistance to heat and moisture. This type is widely used in residential and commercial wiring due to its versatility and cost-effectiveness. When considering purchasing THHN, buyers should evaluate the specific application needs, as it is not suitable for direct burial in the ground, which could limit its use in certain environments.

THWN-2

THWN-2 wire is a waterproof variant of THHN, making it ideal for use in wet locations such as industrial environments or outdoor applications. Its moisture resistance ensures reliability in challenging conditions. Buyers should consider the marginally higher cost of THWN-2 compared to standard THHN, but the added durability often justifies the investment, especially in areas prone to water exposure.

Stranded THHN

Stranded THHN wire consists of multiple strands of copper, providing enhanced flexibility, which is particularly beneficial in applications requiring bending or installation in tight spaces. While the cost is generally higher than solid wire, the ease of installation can reduce labor costs, making it a worthwhile consideration for B2B buyers looking to optimize installation processes.

THHN/THWN-2 Combination

This combination wire takes advantage of both THHN and THWN-2 characteristics, offering versatility across various applications. It is suitable for general-purpose wiring in diverse environments, balancing performance and cost. Buyers should assess whether the increased capabilities align with their project requirements, as this option may be more than what is needed for simpler applications.

XHHW

XHHW wire features cross-linked polyethylene insulation, designed for high-voltage applications. Its excellent thermal performance makes it a prime choice for heavy-duty industrial settings.
