This cable sheath material is flame-retardant; it achieves a smoke light transmittance of over 70% during combustion and exhibits lower toxicity levels compared to standard cables. Key performance characteristics include low smoke density, zero halogen-acid gas emission, a tensile strength exceeding 1.2 kgf/mm², and an operating temperature range of -30°C to 105°C.
1. Safety and Environmental Friendliness: While traditional PVC cables release toxic gases (such as hydrogen halides) and dense black smoke when burning, low-smoke zero-halogen (LSZH) cables utilize eco-friendly materials, effectively preventing "secondary disasters."
2. Excellent Flame Retardancy: Through specialized material formulations and processing techniques, LSZH cables effectively inhibit the spread of fire, buying valuable time for personnel evacuation and firefighting efforts.
3. Electrical Performance: These cables offer higher volume resistivity (typically exceeding 10¹⁶ Ω/cm³) and superior high-voltage resistance (capable of withstanding over 15 kV), resulting in a longer service life.
4. High Mechanical Strength: The tensile strength surpasses that of standard PVC cables (typically >1.2 kgf/mm²), while also offering excellent flexibility, weather resistance (-30°C to 105°C), and non-migratory properties.
