SIMpull THHN® Copper Wire

Application

Southwire® SIMpull THHN® 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. Voltage for all applications is 600 volts. SIMpull THHN® copper conductors are designed to be installed without 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
THWN- Wet locations not to exceed 75° C 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

Construction

Southwire® SIMpull THHN® copper conductors are made with soft drawn copper. Sizes 14 through 4/0 AWG use a combination -unilay stranding while 250 kcmil and larger sizes use a compressed copper stranding. The wire is covered with a tough heat and moisture resistant PVC insulation with an overall nylon jacket utilizing SIMpull® Technology. Available in black, white, red, blue, purple, green, yellow, orange, brown, and gray. Also available in striped configurations. Some colors are subject to economic order quantity. Marked as THHN in all sizes. Also marked as THWN-2 in sizes 8 AWG and larger and in sizes 14, 12, 10 in SIMpull BARREL™ cable drum or SIMpull® CoilPAK™ configurations only. Marked as THWN in sizes 14, 12, and 10 AWG. Marked sunlight resistant in sizes 8 AWG and larger. Sizes 14, 12, and 10 AWG are available with SIMpull® Technology only in SIMpull BARREL™ cable drum or SIMpull® CoilPAK™ configurations.
