FRLS cables are a specific type of electrical cable designed with special properties to enhance safety in case of a fire. The acronym “FRLS” stands for Flame Retardant Low Smoke. These cables are commonly used in buildings, industrial settings, and areas where fire safety is a critical concern.
Here’s a detailed description of FRLS cables:
- Flame Retardant: FRLS cables are made from materials that have flame retardant properties. This means that when exposed to a fire, the cables will resist burning and prevent the flames from spreading along the cable’s length. Flame retardancy helps to contain the fire and reduce the risk of further damage to property and injury to people.
- Low Smoke Emission: During a fire, conventional cables can release dense smoke and toxic fumes, which can hinder evacuation efforts and pose serious health risks to occupants. FRLS cables are designed to emit minimal smoke and non-toxic gases when subjected to fire. This characteristic improves visibility during emergencies and reduces respiratory hazards.
- Reduced Halogen Content: In addition to low smoke emission, FRLS cables are manufactured with reduced halogen content. Halogens, such as chlorine, fluorine, bromine, and iodine, can produce corrosive and toxic gases when exposed to high temperatures. By minimizing halogen content, FRLS cables reduce the potential harm caused by such gases during a fire.
- Applications: FRLS cables are commonly used in various applications, including indoor and outdoor electrical installations, power distribution, communication networks, and control systems. They are particularly favoured in buildings such as hospitals, schools, commercial complexes, data centres, and other places where fire safety is a top priority.
- Construction: FRLS cables have similar construction to standard electrical cables, consisting of one or more conductors made of copper or aluminium, insulated with FRLS materials, and covered with an FRLS jacket. The exact materials used in the construction can vary based on specific industry standards and regulations.
- Compliance: FRLS cables must comply with specific national and international safety standards and certifications. These standards dictate the requirements for flame retardancy, low smoke emission, and reduced halogen content.
