In the field of electrical safety, low Smoke Zero Halogen Cable are revolutionizing industry
standards.Through innovations in both materials and processes, these cables achieve
breakthrough performance:smoke transmittance ≥60% and near-zero halogen gas content
during combustion. Their core advantage lies in: in the event of a fire, their low Smoke Zero
Halogen Cable properties increase escape route visibility by more than four times while
preventing secondary damage from deadly gases like hydrogen chloride. From emergency
lighting in subway tunnels to powering precision equipment in operating rooms,low Smoke
Zero Halogen Cable have become the cornerstone of electrical safety in high-risk locations.
Technology Decoding: The Path to Low Smoke Zero Halogen Cable Properties
Material Revolution:
Using a composite system of cross-linked polyethylene (XLPE) and metal hydroxides,
radiation cross-linking creates a three-dimensional network structure, making the
material stable even at temperatures of 300°C.
Using a specialized process using an internal mixer and twin-screw extruder, they ensure
molecular-level integration of the EVA base material and flame retardants (such as
aluminum hydroxide), achieving a 40% increase in flame retardancy while maintaining
low smoke properties. Performance Verification n flame tests, the Smoke Density
I Index (SDR) oflow Smoke Zero Halogen Cable was ≤15, compared to over 200 for
traditional PVC cables. Toxicity Index (TI) testing showed that the toxicity of its
combustion products was only 1/20 that of PVC cables, meeting the highest
safety level under EU CPR regulations.
Application Scenario: Realizing the Value of low Smoke Zero Halogen Cable Characteristics
Lifeline Protection: In high-rise buildings, low Smoke Zero Halogen Cable can reduce fire
evacuation time by 30%, creating acrucial window for rescue efforts.
Equipment Protection Upgrade: After adopting low Smoke Zero Halogen Cable in data
centers, equipment failure rates due to corrosive gases have decreased by 90%.
Environmental Compliance Benchmark: low Smoke Zero Halogen Cable achieve zero
pollution throughout their lifecycle in specialized locations such as nuclear power plants,
meeting the requirements of the RoHS Directive.
Industry Trend: Global Evolution of LSZH Standards
With the implementation of new standards such as GB/T 19666-2025, the market
penetration of low Smoke Zero Halogen Cable is expected to exceed 60% within three
years. From material nano-sizing to intelligent monitoring integration, low-smoke
halogen-free technology is driving the cable industry to leapfrog development in the
three dimensions of safety, environmental protection, and intelligence.
