<p>The cable, which has increased resistivity to fire propagation and/or the cable being able to operate during fire, consisting of a core (7), formed by at least one conductor (3), where the outer surface of said core (7) can be wrapped around by a foil (5), said cable core (7) being enveloped by a sheath (6). The space inside the sheath (6), enveloping the core (7) with at least one conductor (3) being formed by a central portion (1) and insulation (2), is filled with filling composition (4) in a form of a granulated material composed of 60 to 62 wt. % of SiO2, 29 to 31 wt. % of MgO, 1.25 wt. % of Al2O3, at most 1.0 wt. % of Fe2O3 and of trace elements such as Zn, Ti, Ba and Zr in a form of oxides, the amount of which is at most 1 wt. %.</p> |
