Construction

Conductors:

THHN / THWN-2 / T90 conductor is a soft drawn bare 8000 series aluminum, with Class B stranding per ASTM. Stranded conductors reduce power loss and are also easier to use in applications where flexibility is vital. 

Insulation:

THHN / THWN-2 / T90 has abrasion, heat, moisture, oil, and acid alkaline resistant polyvinyl chloride (PVC) insulation.

Jacket:

THHN / THWN-2 / T90 cables have a clear abrasion, heat, sunlight, moisture resistant, and low coefficient of friction nylon jacket. Standard stock colors include: black, red, blue, white, brown, orange, yellow, gray, purple, and green.
