    摘要: A flame-retardant cable (10;20;30;40;50) having at least one core (31;41;51) comprising a conductor (11), and at least one protecting layer (13a; 13b; 14; 15; 47) surrounding the cable core (31;41;51), wherein the protecting layer (13a; 13b; 14; 15; 47) is made from a low smoke zero halogen (LS0H) flame-retardant polymer composition comprising at least 70 phr of a polyethylene homopolymer or copolymer having a density lower than 0.90 g/cm 3 as halogen-free polymeric base added with
    a) from 100 to 800 phr of at least one metal hydroxide; and
    b) at least 10 phr of a tannin.
    The cable has improved reaction to fire performances, in particular a reduced or null dripping under fire, which render it compliant with the requirements of the more recent international standards.
