In modern infrastructure, safety is a top priority. Low Smoke Zero Halogen (LSZH) cables, also known as Low Smoke Fume (LSF) cables, play a vital role in ensuring protection during fire incidents.
Unlike traditional PVC cables, LSZH cables are manufactured from halogen-free thermoplastic compounds. When exposed to fire, they release very limited smoke and no harmful halogen gases. This not only minimizes the risk of toxic exposure but also improves visibility, enabling safer evacuation and more effective firefighting operations.
PVC cables, on the other hand, generate dense black smoke and poisonous halogen gases while burning. This can quickly fill enclosed spaces, making escape routes invisible and causing occupants to lose consciousness within minutes—often before the fire itself reaches them. LSZH cables reduce these risks significantly, giving occupants valuable time to evacuate safely.
Because of their fire-safety advantages, LSZH cables are increasingly used in environments where people live or work near cable systems with limited ventilation. Common applications include skyscrapers, malls, commercial complexes, railways, tunnels, marine vessels, aerospace, and military facilities.
Extensive testing standards, such as IEC and BS EN protocols, ensure LSZH cables meet stringent fire safety performance. These tests include flame propagation resistance, smoke emission levels, oxygen index, and acid gas measurements—all confirming LSZH’s superior safety features.
Importantly, LSZH cables provide these benefits with only a minimal cost difference compared to standard cables, making them a cost-effective and future-proof choice for modern projects.
By using CN Cable’s Low Smoke and Fume (LSF/LSZH) products, contractors and developers can enhance building safety, reduce fire hazards, and protect lives and property. With their flame-retardant and non-toxic properties, CN Cable’s LSZH cables slow fire spread, reduce smoke, and prevent harmful gas release—ensuring critical extra time for evacuation and firefighting.
