Aluminum THHN Wire Application
Aluminum THHN wire is commonly used in various electrical applications such as power distribution, conduit wiring, and outdoor installations. It is ideal for feeding electrical panels, wiring branch circuits, and connecting heavy machinery due to its high current capacity and lightweight nature. When properly installed with compatible connectors and in accordance with electrical codes, aluminum THHN wire provides a cost-effective and reliable solution for both indoor and outdoor wiring needs.

Aluminum THHN Wire Construction
THWN THHN aluminum wire is made of aluminum conductor , they are also insulated with an uniform layer of Chloride of Polyvinyl (PVC) thermoplastic material resistant to the moisture and the heat, over which it is applied a protector coating of Nylon or Polyamide. They can be supplied in varied colors according to their size and with different packaging.
