    摘要: The present invention relates to a cable comprising one or more insulated conductors which are embedded in a bedding composition, which comprises a) a polymer resin (A) and b) an inorganic filler (B), wherein the polymer resin (A) comprises an olefin homo- and/or copolymer (A.1) which has a weight average molecular weight Mw of 10,000 g/mol or more and a molecular weight distribution MWD of 4.5 or lower and, in a second aspect, to a cable comprising one or more insulated conductors which are embedded in a bedding composition, which comprises a) a polymer resin (A) and b) an inorganic filler (B), wherein the heat release rate HRR of the composition at any time within is the period from 0 s to 200 s after ignition does not exceed a maximum of 80 kW measured with cone calorimetry according to ISO 5660-1. The bedding may also comprise a bedding layer provided between said one or more insulated conductors and an outer sheath layer, wherein the bedding layer comprises the above bedding composition.
