"The Global Standard for Versatile and Efficient Electrical Wiring"

As a global benchmark for commercial and industrial wiring, THHN/THWN-2 features a dual-rated design optimized for both dry (THHN) and wet (THWN-2) environments.

Engineered with a smooth outer nylon jacket over robust PVC insulation, it minimizes friction during installation to maximize labor efficiency while delivering a highly durable and cost-effective electrical solution.

Main Applications

General power distribution in commercial and residential facilities, conduit and cable tray applications, and dedicated lighting & control circuits.

Key Features

Heat Resistance: Maintains a high allowable temperature of 90°C in wet locations as well as dry locations.
Installation Efficiency: The nylon jacket reduces friction, making it extremely easy to pull the wire through complex conduits.
Oil & Chemical Resistance: The nylon layer protects the insulation from gasoline, oil, and various chemical substances, maintaining long-term stability.
