SPEC 87010

Cable-in-Conduit (CIC) CU 600V THHN SCH 40



• Conductors: Copper SIMpull THHN/THWN-2® per SPEC 10000
• Conduit: High-Density Polyethylene (HDPE)

Applications and Features:

Southwire’s SIMpull® CIC has been utilized by end users in various applications, including the US Department of Transportation (DOT), the US Department of Energy (DOE), commercial constructions, EV infrastructure expansions, Utility grid-hardening efforts, airports, mass transit, renewables, petrochemical, agriculture, and data centers. Manufactured by continuously extruding HDPE loosely around the cable assembly with no adhesion between the conduit and the cable, thus leaving the cables free in the conduit. Lubrication is applied to the cable, allowing for cables to be pulled out and replaced if necessary.
