THHN Wire | Thermoplastic High Heat Nylon Wire
THHN wire stands for Thermoplastic High Heat Resistant Nylon wire, a type of electrical wire used in residential and commercial constructions. Thwn-2 wire is made of finely stranded copper conductors wrapped with PVC insulation and a nylon sheath, which enhances the wire’s durability. Thhn/thwn wire is rated at 90 degrees Celsius in a dry environment and has a voltage rating of 600v

Additional Information
What is THHN meaning?
THHN stands for thermoplastic high-heat nylon. The “T” in THHN refers to the insulation material made of polyvinyl chloride (PVC), a thermoplastic material. The “HH” in THHN indicates that the wire is highly heat resistant, making it suitable for high-temperature environments. The “N” in THHN refers to the nylon jacket.
What is THHN wire Specification?
THHN/THWN-2 wire is manufactured in 19 strands and more than 37 strands. These cables are available in different gauges, which are 10 AWG, 12 AWG, and 14 AWG. They are specifically designed to be used in wet and dry locations and are approved for direct burial in the ground.
Types of THHN Wire
Different types of wires and cables are similar to the THHN wires available on the market. Some of them are THWN, a wire resistant to heat and water and made of thermoplastic material. Another one is THHW, which is also made of thermoplastic material and is heat- and water-resistant. TFFN is a flexible nylon wire made of thermoplastic.
THWN Wire:
THWN is suitable for dry and wet conditions at a maximum temperature of 75ºC. The insulation is PVC, and the sheath is nylon.
THWN-2 Wire:
THWN-2 wire can handle wet conditions at a higher temperature up to 90ºC.
THHW Wire:
THHW wire does not have a nylon jacket. It is safe to use in dry conditions at up to 90ºC and in wet conditions at up to 75ºC.
TFFN Wire:
TFFN wire is a type of wire that is used in buildings. It is known for its flexibility and has a nylon jacket.
