Application
Ideal for cable tray installation, wire ways, open wiring, conduits, service entrance, feeders, and branch circuits for permanent
installations. Suitable for power and lighting installations in residential, commercial, and industrial establishments.
Temperature rating not to exceed:
• THHN/THWN: 90°C dry and damp, 600V
• THHN/THWN: 75°C wet or in oil, 600V
• THWN-2: 90°C dry, wet or in oil, 600V
Features
• CT-rated lead-free THHN/THWN cables are insulated with special PVC formulation that makes it more flame retardant than ordinary
THHN cables. • More tolerant to heat with its better flameretardant PVC. • The insulation is made of materials that do not contain
lead as stabilizer making it “environment friendly”. • The nylon jacket offers mechanical protection and resistance to petroleum
byproducts, chemical reagents, and oils. It is also abrasion-resistant, allows higher gliding and greater ease in installation. •
Available in black, white, red, blue, green, and yellow colors. Other colors available upon request.
