Abstract (en)

[origin: WO2009146858A1] The invention relates to a wire for use in electric cables, having a fire-resistant insulation based on cross-linkable polymers comprising ceramic-forming additives, said insulation surrounding a conductor (10), wherein the insulation has a first layer (11) comprised of a first composition, and a second layer (12) comprised of a second composition surrounding the outside of the first layer (11), wherein the first and the second compositions are set such that a ceramic forms in the composition constituting the second outer layer (12) at a lower temperature range than that in the composition constituting the inner first layer (11).
