THHN cable (Thermoplastic High Heat-resistant Nylon-coated wire) is one of the most widely used building wires in commercial, industrial, and residential electrical installations. It features a copper conductor, PVC insulation, and a durable nylon jacket, providing excellent heat resistance, abrasion resistance, and easy pulling through conduits.
THHN wire is commonly installed in conduit systems, control panels, machine tools, switchboards, and power distribution equipment where reliable electrical performance and long service life are required.
| Layer | Material | Function |
|---|---|---|
| Conductor | Bare Copper / Tinned Copper | Electrical conductivity |
| Insulation | Heat-resistant PVC | Electrical insulation |
| Jacket | Nylon (Polyamide) | Mechanical protection and abrasion resistance |
THHN wire is rated for continuous operation up to 90°C in dry locations, making it suitable for demanding electrical environments.
The nylon outer jacket provides additional protection against:
The smooth nylon surface reduces friction, allowing faster wire pulling through conduits and cable trays.
THHN cable performs well in environments exposed to:
The combination of PVC insulation and nylon jacket ensures excellent aging resistance and stable electrical performance over time.
Available from small control wiring sizes to large power distribution conductors.

THHN stands for:
T – Thermoplastic
H – Heat Resistant
H – High Heat Resistant
N – Nylon Coated
It refers to a PVC-insulated electrical wire protected by a nylon outer layer.
THHN wire itself is primarily designed for dry locations. However, many modern THHN products are dual-rated as THHN/THWN-2, which can be used in both dry and wet locations when installed according to local electrical codes.
| Item | THHN | THWN |
|---|---|---|
| Dry Location Rating | 90°C | 75°C/90°C |
| Wet Location Rating | Limited | Suitable |
| Water Resistance | Standard | Enhanced |
| Typical Use | Indoor conduit wiring | Indoor & outdoor conduit wiring |
Many cables today carry both THHN and THWN-2 ratings.
The nylon jacket provides:
This makes THHN wire more durable than standard PVC-insulated wire.
Yes. THHN cable is widely used in:
Its excellent heat resistance and mechanical durability make it a preferred choice for industrial environments.
THHN cable is a reliable and cost-effective building wire designed for power distribution, control circuits, and general electrical installations. With its copper conductor, heat-resistant PVC insulation, and protective nylon jacket, THHN wire offers outstanding electrical performance, durability, and installation efficiency. Whether for commercial buildings, industrial facilities, or residential projects, THHN cable remains one of the most trusted wiring solutions worldwide.
