600 Volts. Copper Conductor. PVC Insulation/Nylon Sheath THHN/THWN-2. Heat, Moisture, Gasoline and Oil Resistant II. SIMpull® Technology for Easier Pulling.
1. Conductor: Sizes 8 - 3/0 AWG use a stranded combination-unilay soft drawn annealed bare copper per ASTM B3 and B787. Sizes 4/0 AWG and larger use a stranded compressed annealed bare copper per ASTM B3 and B8.
2. Insulation: Heat and moisture resistant Polyvinyl Chloride (PVC)
3. Sheath: Nylon jacket utilizing SIMpull® Technology
Southwire SIMpull® THHN/THWN-2 copper conductors are primarily used in conduit and cable trays for services, feeders, and branch circuits in commercial or industrial applications as specified in the National Electrical Code® and other applicable codes and standards. Voltage for all applications is 600 volts. SIMpull® THHN/THWN-2 copper conductors are designed to be installed without the application of a pulling lubricant. These conductors have multiple ratings depending upon the product application. Allowable temperatures are as follows:
• THHN or T90 Nylon: Dry locations not to exceed 90°C
• THWN-2: Wet or dry locations not to exceed 90° C or locations not to exceed 75°C when exposed to oil
• TWN75: Wet locations not to exceed 75°C
• MTW: Wet locations or when exposed to oil at temperatures not to exceed 60°C or dry locations not to exceed 90°C (with ampacity limited to that for 75°C conductor temperature per NFPA 79)
• AWM: Dry locations not to exceed 105°C only when rated and used as appliance wiring material
