Halogen-free cables according to IEC 60754-1 or DIN EN 60754-1. In short, this part of the standard defines the test equipment and the procedure for determining the amount of halogen acid gas that is formed when the materials are burned in cables and insulated wires.
The use of low-smoke, halogen-free (LSHF) cables in commercial and residential building projects can help reduce equipment damage and reduce smoke toxicity.
Halogen-free cable glands are identified by the letters HF. The SKINTOP® ST-HF-M cable gland and the SILVYN® shrink tubing are flame-retardant and self-extinguishing, halogen-free and offer a high level of functional reliability.
Jul 18, 2018 · IEC 62821 covers requirements for halogen-free, low-smoke thermoplastic insulated and sheathed cables with voltage ratings up to 750 volts. UL’s HF and LZSH markings can be used on many types of wire and cable, from appliance wiring to communications cable (including fiber optic), flexible cord, and power and control tray cable.
The primary low-smoke or halogen-free cables include low smoke, zero halogen (LSZH), low smoke and fume (LSF) and fire retardant and noncorrosive (FRNC). The chart below provides a breakdown of each low-smoke option and some of the key characteristics to
There are several halogen-free materials that can be used for cables. These include EVA, Polyamides, EPR, EPDM, PE, PP, SHF1 and SHF2. You can read all about SHF1 and SHF2 in the blog ‘ ‘SHF1 and SHF2 outer jackets according to NEK 606 ’.
What are halogen free cables, and how do they help? When we refer to halogens, we’re talking about a group of elements in the periodic table known to have harmful properties: Fluorine, Chlorine, Bromine and Iodine.
