The invention discloses a silicone rubber cable for rail transit and an intelligent silicone rubber preparation method of the silicone rubber cable. The silicone rubber cable comprises a conductor and an insulation layer, wherein the outer side of the conductor is covered with the insulation layer, n raised strips adopting the same structure are arranged on the surface of the insulation layer, an included angle between adjacent raised strips is 40-60 degrees, and each raised strip is 0.1-0.5 mm high. The silicone rubber is applied to insulation and jacket materials of high-temperature cables of rail transit vehicles, and the performance of the cable can meet the requirements for indexes of a jumper cable at a joint of carriages and a power cable of a traction motor in a bogie. The performance of a traditional silicone rubber cable material is improved, the silicone rubber cable has excellent performance including high strength, high-temperature resistance, cold resistance, ageing resistance, water resistance, moisture resistance, long service life and the like, normal power supply performance of the cable in a longer time can be guaranteed under a flame condition, and a flame retarding effect is realized. Intelligent mixing and production are adopted for preparing the novel silicone rubber cable material, labor cost is saved, precise mixing can be realized, and the uniformity of batches is met.
