THHN / THWN Nylon-Jacketed Wires

TFFN, THHN and THWN wires are designed for special-purpose applications requiring high heat and water resistance, with a maximum operating temperature of 105°C. The stranded conductor complies with SASO GSO IEC TR 62602. The insulation is a special heat-resistant PVC compound rated 105°C, and a nylon jacket is extruded tightly over the insulation for extra mechanical protection.

  • Special heat-resistant PVC insulation rated 105°C.
  • Tough nylon jacket extruded tightly over the insulation.
  • Stranded copper conductor to SASO GSO IEC TR 62602.
  • Ideal for high-heat, damp and special-purpose locations.
