LSZH Leather Line Cable Material - High-Quality, Environmentally Friendly Sheathed Cables from China Suppliers & Factory
Product Features
1. Weather resistance
Low smoke zero halogen sheath cable material is appropriate for both indoor and outdoor applications since it can tolerate the effects of daily weather conditions, such as sunlight, rain, and humidity.
2. High fire resistance
Materials with low smoke zero halogen sheaths typically possess a high fire resistance, which helps shield the insulation within cables during a fire and stop it from spreading.
3. Low smoke combustion
In the event of a fire, low smoke zero halogen sheath cable material produces less smoke, which enhances crew evacuation safety.
4. Low toxicity
Low smoke zero halogen sheath cable material typically creates less harmful gas even when burning, lowering the possibility of toxicity in a fire.
5. Protection of the environment
This sheath material's zero halogen composition lessens its negative effects on the atmosphere and the ozone layer.
Scope of Use
Cable and optical cable, coaxial cable, network cable, elevator cable, etc.
