THHN/THWN/THWN-2 UL83 Nylon wire THHN single core wire characteristics and advantages

1. Nylon thread has superior safety properties such as termite resistance, rat bite resistance, and good heat resistance (up to 200 degrees Celsius)

2. Nylon wire has no harm to the surrounding environment, is green and environmentally friendly, and is the best wire for home decoration equipment power and lighting

3. It is lightweight and has a smooth appearance. Due to the lubricity of nylon itself, it is not easy to scratch when threading, making it easy to lay through pipes, bringing convenience and economy to installation and laying

4. Using nylon as the sheath, it has a bright appearance, low heat resistance deformation, and excellent thermal stability

5. Has high mechanical strength and excellent wear resistance, cold resistance, surface hardness, bending strength, impact strength, chemical resistance, oil resistance, gasoline resistance, and self-lubrication

6. Widely used in the United States and Europe, nylon sheaths effectively solve fire accidents caused by defects in ordinary wires and cables
