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.
