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 600V. SIMpull THHN® copper conductors are designed to be installed without application of a pulling lubricant. Made with soft-drawn copper and a combination-unilay stranding. Covered with a tough heat- and moisture-resistant PVC insulation with an overall nylon jacket using SIMpull® tehcnology.
