Applications
Low friction type THHN or THWN-2 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 2001.

When used as Type THHN, conductor is suitable for use in dry locations at temperatures not to exceed 90°C.  When used as Type THWN-2 or TWN75 conductor is suitable for use in wet or dry locations at temperatures not to exceed 90°C or not to exceed 75°C when exposed to oil or coolant.  Voltage rating for cable is 600V.
This product is designed to be installed without the application of pulling lubricant.

Construction
Conductor
: Compact stranded AA-8000 series aluminum conductor material  per ASTM B800, ASTM B801, ASTM B836, ASTM B901 (Single Input Wire), as applicable.

Insulation:  Low coefficient of friction, abrasion, moisture, and heat resistant polyvinyl chloride (PVC).
Jacket:  Low coefficient of friction, abrasion, moisture, and heat resistant nylon polyamide jacket.
