Low smoke and halogen free cabling is becoming increasingly necessary to protect against the risk of toxic gas emissions during a fire. Standard RG cables contain halogen insulation. Halogen insulation was first used because it helps prevent cables from fire, but if it does ignite, the resulting fumes are highly toxic and a major risk, both to human life and to circuitry in place: critical, for example, in an aircraft.
Halogen free cables are engineered and designed so that emissions during a fire offer low toxicity and low smoke. This type of cabling is increasingly of relevance in public sector housing and major new developments. It could be increasingly worthwhile and of interest when it comes to elderly housing too, where items such as disabled stair liftsare in use and the risk of additional complications as a result of fire significant.
If you intend using halogen free cabling it is worth noting that most types of zero-halogen cabling still work with the same standard and circular connectors used with RG cables. Many advocates of halogen free cable also argue that it is lower in weight, so overall system weights can be reduced, while also offering greater flexibility over standard RG cabling
Why Halogen Free?
