The invention discloses a cable material which comprises the following raw materials: PVC (polyvinyl chloride)-SG1, PVC-SG2, silicon rubber, coumarone resin, dioctyl sebacate, trioctyl phosphate, epoxy n-butyl stearate, trimethyl phosphate, hexanediamine, phenylurea, ethyl acetate, maleic anhydride, poly-L-lactic acid, styrene, a silane coupling agent KH-560, ammonium persulfate, antimony oxide, oxidized paraffin, barium stearate, nano-sized aluminum nitride, wood fiber powder, calcium carbonate, glass fibers, nano-sized magnesium oxide, pot clay, bisphenol A, polysiloxane, ammonium polyphosphate, paraffin oil, a silane coupling agent KH-550 and wollastonite. The cable material is prepared by the following steps: mixing basic materials, all modified materials and accessories, stirring andheating the mixture, increasing pressure, discharging rubber, preparing a film and the like. The invention also provides a low temperature resistant cable and a low temperature resistant three-core super-flexible cable that are prepared from the cable material. The cables provided by the invention have low temperature resistance and high temperature resistance and are excellent in toughness.
