H07Z1-U, H07Z1-R (TSE)
450/750 V halogen free and flame retardant single core cables are designed for
electrical installations where enhanced fire safety and low smoke emission are
required. These cables are manufactured with copper conductors and halogen-free
insulation materials that minimize toxic gas release in case of fire.
Thanks to their flame retardant properties and environmentally friendly structure,
these cables are especially suitable for installations in public buildings,
commercial facilities, and areas with high human occupancy.
Applications
- Electrical installations in public buildings
- Commercial and residential buildings
- Hospitals, schools, and shopping centers
- Industrial control panels and switchboards
- Areas requiring low smoke and toxic gas emission
Halogen free single core cables are widely used in applications where fire safety,
low smoke density, and reduced toxic gas emission are critical for human safety.
Cable Construction
- Conductor: Solid copper conductor
- Insulation: Halogen free, flame retardant compound
- Core Identification: Color coded
Halogen free single core cables are manufactured using special insulation compounds
that do not emit corrosive or toxic gases during combustion. This construction
significantly improves safety in fire situations while maintaining reliable
electrical performance for fixed installations.
