In the last decade, there has been an increasing trend for halogen-free cable, because LSZH (Low Smoke Zero Halogen) designations emit limited smoke and no halogen when exposed to high temperatures or when it comes into direct contact with fire.
Transit Cable & Halogen-Free Cable
These amazing cables were first discovered by Richard Skipper in 1979 and patented by Raychem Corporation. This innovative invention resolved the major challenge of merging adequate inorganic filler ALTH, in order to stop fire and char from forming on cables. Without these LSZH options if a fire were to break out the alternative wiring option would release large amounts of noxious gases and carbon minerals. These halogens are also known to hurt not only the environment but also severally affect human health if inhaled, which is why they're typically used where groups of people are consistently in close proximity to the intended applications.
• Fluorine • Chlorine • Bromine • Iodine • Astatine
These 5 compounds are typically used because of their reliability and relatively low pricing. The halogenated products are typically difficult to duplicate in price and performance, which is why they're used so frequently within today's applications. For example, PVC or polyvinyl chloride is one of the most used products to date, because of its low cost, its versatility and performance. PVC’s low cost and high performance make it very difficult to replicate, but if set on fire or if it began to smoke the resulting fumes would poison and potentially kill any plant, animal or human life in the vicinity.
So why use LSZH if the price is higher and health isn’t a concern?
This is a very large reason why in North America and other parts of the world people do not consistently use them, but on that point, there are other areas around the world that have passed legislation making it illegal to use halogenated products in a large majority of applications. Two major areas that have implemented strict laws on LSZH cables are the European Union and Japan. These legislations aren’t aimed specifically at the possibility of fire releasing the halogens; the directives were put in place to prevent this highly toxic group from entering landfills and incinerators. The Transit cables and Halogen-free cables have thus become "green" products of the wire and cable world. The RoHS (Restriction of Hazardous Substances), WEEE (Waste Electrical and Electronic Equipment), GPSSI (Japan Green Procurement Survey Standardization Initiative) and many more demonstrate the changes that are being pursued by countries around the world. With society switching constantly to green alternatives, countries around the world will continue to slowly adapt to sustainable and affordable alternatives.
