How does the LSZH sheath improve safety in fire scenarios?

The low-smoke zero-halogen (LSZH) sheath emits minimal smoke and no corrosive or toxic halogen gases when exposed to flame, significantly enhancing occupant safety and protecting sensitive electronic equipment during a fire. This characteristic is critical in enclosed public spaces, industrial control rooms, and data halls. The LSZH formulation meets the fire-performance requirements of IEC 60502 and associated GB/T standards, ensuring the cable can be used in circuits where fire-resistant and circuit-safe design is mandated without compromising the environmental and human safety profile of the installation.
