Characteristics of low smoke halogen-free irradiated flame retardant wire

1. It has excellent mechanical and physical properties and good resistance to environmental stress cracking.

2. Resistant to various chemical solvents and relatively stable in various corrosive media around.

3. Stable electrical and insulation performance.

4. The wire has good heat resistance, and the long-term working temperature reaches 90 ℃ - 150 ℃.

5. Large current carrying capacity and strong overload capacity.

6. The product does not contain halogen elements and does not produce toxic and corrosive gases such as hydrogen chloride during combustion.

7. When burning, the smoke is small and the visual distance is long. In case of fire, it can ensure that people who are not familiar with the scene have the opportunity to escape.

8. It has excellent flame retardancy.

Main technical indexes of low smoke halogen-free irradiation flame retardant wire

1. The 20 ℃ DC resistance of copper conductor shall meet the requirements of GB / t3956.

2. AC voltage test: 2500V, no breakdown for 5 minutes.

3. The flame retardant performance shall meet the relevant type requirements of GB / t18380.

4. Gas released during cable combustion: pH value ≥ 4.3, conductivity ≤ 10 μ S/mm。 When the cable is burning, the light transmittance is greater than 60%.
