SPEC 87010

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



• 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.
• All cables are installed as single conductors or paralleled in HDPE conduit and are available in Standard Wall, Schedule 40, Schedule 80, SDR 13.5, SDR 11, and EPEC-17.

Applications and Features:

Commonly installed from transformer to transformer or as underground cables exiting substations
