Faible fum\u00e9e sans halog\u00e8ne<\/strong>, connu \u00e9galement sous le nom de ruban LSZH (Low Smoke Zero Halogen ou faible \u00e9mission de fum\u00e9es sans halog\u00e8ne), est un ruban de liage et d'enrubannage ignifuge sp\u00e9cialis\u00e9, utilis\u00e9 \u00e0 l'int\u00e9rieur des c\u00e2bles d'alimentation, de commande, d'instrumentation et r\u00e9sistants au feu. Il sert de couche de liage d'\u00e2me ainsi que de barri\u00e8re \u00e0 l'oxyg\u00e8ne et de couche ignifuge. Lorsqu'il est expos\u00e9 au feu, le ruban absorbe la chaleur, forme une couche isolante carbonis\u00e9e stable, restreint l'acc\u00e8s de l'oxyg\u00e8ne \u00e0 l'isolation, supprime la propagation des flammes et ne d\u00e9gage qu'une fum\u00e9e minime, non toxique et non corrosive.<\/p>\n

Contrairement au PVC conventionnel ou aux rubans halog\u00e9n\u00e9s, le ruban LSHF\/LSZH ne contient ni chlore, ni fluor, ni brome, ni iode. Les gaz de combustion restent presque neutres (pH \u2265 4,3, faible conductivit\u00e9), prot\u00e9geant ainsi \u00e0 la fois les personnes et les \u00e9quipements \u00e9lectroniques sensibles. Cela le rend indispensable pour les c\u00e2bles install\u00e9s dans des espaces confin\u00e9s ou \u00e0 forte occupation.<\/p>\n

Principaux avantages techniques pour les fabricants de c\u00e2bles<\/strong><\/h3>\n
    \n
  • Faible \u00e9mission de fum\u00e9e<\/strong>: Offre une transmission lumineuse \u00e9lev\u00e9e (g\u00e9n\u00e9ralement > 60% selon la norme CEI 61034), ce qui am\u00e9liore la visibilit\u00e9 lors des \u00e9vacuations.<\/li>\n
  • Sans halog\u00e8ne<\/strong>: Teneur en gaz acides \u2264 0,51 TP3T (CEI 60754-1), pH \u2265 4,3 et conductivit\u00e9 \u2264 10 \u00b5S\/mm (CEI 60754-2). Pas de formation d'HCl corrosif.<\/li>\n
  • Haute r\u00e9sistance au feu<\/strong>: Indice d'oxyg\u00e8ne (LOI) g\u00e9n\u00e9ralement \u2265 30% (qualit\u00e9s pour non-tiss\u00e9s) et pouvant atteindre \u2265 50% (qualit\u00e9s enduites haute performance). Indice de temp\u00e9rature souvent \u2265 450 \u00b0C.<\/li>\n
  • Performance m\u00e9canique sup\u00e9rieure<\/strong>: L'allongement contr\u00f4l\u00e9 (g\u00e9n\u00e9ralement \u226512\u201315%) permet un enroulement serr\u00e9 et uniforme, sans fissures ni rel\u00e2chement au niveau du diam\u00e8tre ext\u00e9rieur. La r\u00e9sistance \u00e9lev\u00e9e \u00e0 la traction \u00e9vite toute rupture lors du c\u00e2blage \u00e0 grande vitesse. La texture souple garantit un aspect lisse de la gaine et une utilisation optimale du rouleau.<\/li>\n
  • Adapt\u00e9 aux processus<\/strong>Non toxique, inodore, n'affecte pas la capacit\u00e9 de transport de courant du c\u00e2ble ni les performances \u00e9lectriques \u00e0 long terme. Bonne stabilit\u00e9 dimensionnelle aux temp\u00e9ratures de transformation.<\/li>\n
  • Conformit\u00e9 environnementale et r\u00e9glementaire<\/strong>Sans amiante, sans m\u00e9taux lourds, conforme aux exigences RoHS, REACH et CPR \/ EN 50575 modernes lorsqu'il est utilis\u00e9 dans des constructions de c\u00e2bles LSZH compl\u00e8tes.<\/li>\n<\/ul>\n

    Structure des mat\u00e9riaux et principe de fonctionnement<\/h3>\n

    Le ruban utilise un tissu en fibre de verre E sans alcali comme support de base. Les deux surfaces sont impr\u00e9gn\u00e9es et rev\u00eatues d'un syst\u00e8me ignifuge sans halog\u00e8ne formul\u00e9 avec pr\u00e9cision, \u00e0 base d'hydrates m\u00e9talliques (principalement du trihydrate d'aluminium ATH ou de l'hydroxyde de magn\u00e9sium MDH) combin\u00e9s \u00e0 des liants synergiques. Apr\u00e8s enduction, le mat\u00e9riau est cuit, durci et d\u00e9coup\u00e9 avec pr\u00e9cision aux largeurs requises.<\/p>\n

    Lorsqu'expos\u00e9 au feu :<\/p>\n

      \n
    • Les hydrures m\u00e9talliques se d\u00e9composent de mani\u00e8re endothermique, en absorbant de grandes quantit\u00e9s de chaleur et en lib\u00e9rant de la vapeur d'eau.<\/li>\n
    • Une couche charbonis\u00e9e stable et isolante se forme, ce qui restreint l'acc\u00e8s de l'oxyg\u00e8ne \u00e0 l'isolation sous-jacente.<\/li>\n
    • La densit\u00e9 des fum\u00e9es reste faible et les gaz de combustion sont essentiellement exempts d'acides halog\u00e9n\u00e9s.<\/li>\n<\/ul>\n

      Cette double action (absorption de chaleur + barri\u00e8re \u00e0 l'oxyg\u00e8ne) aide le c\u00e2ble fini \u00e0 satisfaire la triade fondamentale de performance au feu des normes CEI 60332 (propagation de la flamme), CEI 60754-1\/2 (gaz d'acide halog\u00e9n\u00e9 et acidit\u00e9\/conductivit\u00e9) et CEI 61034-2 (densit\u00e9 des fum\u00e9es).<\/p>\n

      Primary Applications in Cable Construction<\/h3>\n
        \n
      • Core binding and filler retention in multi-core power, control and instrumentation cables.<\/li>\n
      • Oxygen-barrier \/ flame-retardant layer in fire-resistant cables (often combined with mica tape).<\/li>\n
      • Bedding or separation layer under LSZH outer sheaths.<\/li>\n
      • Marine, offshore, nuclear, tunnel, data-centre, hospital and high-rise building cables where low smoke and non-corrosive gases are mandatory.<\/li>\n
      • Small-section flexible cables and high-flame-retardant constructions requiring thin, soft wrapping without increasing overall diameter excessively.<\/li>\n<\/ul>\n

        Performance Contribution to Finished Cable Standards<\/h3>\n

        When correctly applied (typically 20\u201350 % overlap depending on design), the tape contributes directly to:<\/p>\n

          \n
        • IEC 60754-1: Halogen acid gas \u22645 mg\/g<\/li>\n
        • IEC 60754-2: pH \u22654.3 and conductivity \u226410 \u00b5S\/mm<\/li>\n
        • IEC 61034-2: Minimum light transmittance \u226560 % (premium constructions often exceed 80 %)<\/li>\n
        • IEC 60332-1 \/ 60332-3 series flame propagation<\/li>\n
        • Supporting higher CPR Euroclasses (B2ca-s1,d1,a1 or Cca) and regional requirements (EN 45545 for rail, GB 31247 B1 for China, etc.)<\/li>\n<\/ul>\n

          Selection and Application Notes for Engineers<\/h3>\n
            \n
          1. Thickness selection is driven by required oxygen barrier performance versus finished cable diameter and flexibility targets. 0.15\u20130.18 mm grades are preferred for flexible or small-section cables; 0.20\u20130.25 mm for heavier power cables.<\/li>\n
          2. Ensure the tape has adequate elongation (\u226515 %) to avoid cracking or loose wrapping after sheathing, especially in winter production conditions.<\/li>\n
          3. Compatibility with subsequent extrusion (LSZH or XLPE compounds) must be verified; residual solvents or improper curing can affect adhesion or electrical properties.<\/li>\n
          4. Storage: keep sealed, dry, 10\u201330 \u00b0C; shelf life typically 12 months.<\/li>\n
          5. Custom widths, higher oxygen-index formulations, and dual-side coated variants are routinely available for long-term OEM programmes.<\/li>\n<\/ol>\n

            \"Low<\/p>\n

            Key Technical Takeaways<\/h3>\n
              \n
            • LSHF \/ LSZH tape is not merely a binder; it is an active fire-performance component that absorbs heat, forms a protective char, and keeps smoke and corrosive gases to levels required by modern safety codes.<\/li>\n
            • Glass-fiber substrate + metal-hydrate coating delivers oxygen indices \u226550\u201355 % and smoke densities \u2264100\u2013150 while maintaining mechanical integrity.<\/li>\n
            • Correct grade selection and wrapping technique directly influence the ability of the finished cable to pass IEC 60754, IEC 61034 and higher CPR classifications.<\/li>\n
            • Long-term reliability depends on consistent coating quality, dimensional stability and supplier process control.<\/li>\n<\/ul>\n
