halogen-free

No corrosive fire gases are produced during combustion. High smoke development and rapid fire propagation can also be caused by halogen-free cables. (All data without guarantee)

Halogen-free wires and cables

Halogen-free wires and cables have been developed to minimise the flue gas density of burning PVC wires and cables. Today, halogen-free means no release of hydrochloric acid when burning wires and cables, no generation of hazardous waste, no flue gas development, no corrosive loads for electronic and other systems (through cable ducts), for steel and concrete. Halogen-free wires and cables are used where there is a high concentration of people and property, such as in high-rise buildings, schools, hospitals, retirement homes, airports, IT centres and other control systems, etc. (All information without guarantee)
