Abstract: A cable having at least one conductor and at least a fire resistant coating layer. The fire resistant coating has (a) at least an organic polymer having a combustion temperature range between a minimum value T1 and a maximum value T2; (b) at least a glass frit; and (c) at least an inert compound. The inert compound (c) has a softening point or a melting temperature of not less than 1000° C.; the glass frit (b) reaches a viscosity of between 107 poise and 108 poise in a selected temperature range including the combustion temperature range of the organic polymer (a). The selected temperature range is such that the glass frit (b) flows over the inert compound (c) and the burned organic polymer (a) so as to form a solid char fire resistant coating layer.
