The LSZH (Low Smoke Zero Halogen) Flexible Cable is designed for environments requiring high safety performance, flexibility, and minimal emission of toxic gases during fire. It is manufactured with halogen-free materials that produce very low smoke and no corrosive gases when exposed to flames. These cables are ideal for use in public buildings, tunnels, subways, ships, and industrial installations where human life and sensitive equipment must be protected.
- Halogen-free and environmentally friendly
- Emits minimal smoke and no toxic or corrosive gases during combustion
- Excellent flexibility for easy installation
- High mechanical strength and oil resistance
- Superior flame-retardant performance (IEC 60332-3 compliant)
- Excellent electrical and thermal stability
- Long service life and high reliability
