Low Smoke Zero Halogen Photovoltaic Insulation, Sheath Cable Material (LSZH Photovoltaic Insulation, Sheath Cable Material)
1. Environmental resistance: It can withstand outdoor, ultraviolet, temperature changes and adverse weather conditions to ensure reliability in various climatic conditions.
2. Anti-ultraviolet attenuation: It has anti-ultraviolet attenuation characteristics to extend the service life of the cable.
3. Good electrical insulation: Ensure that the cable can still provide safe power transmission under high voltage, reducing the risk of electric shock and fire.
4. Low smoke combustion: Low smoke zero halogen material produce less smoke in the event of a fire, which helps to improve the safety of personnel evacuation.
5. Low toxicity:Low smoke zero halogen material usually have low toxicity, even when burning, they produce less toxic gas, helping to reduce the risk of toxicity in a fire.
6. High fire resistance: Low smoke zero halogen material usually have high fire resistance, which can protect the insulation material inside the cable in a fire and prevent the spread of fire.
7. High conductivity: It can provide efficient power transmission and reduce resistance loss.
