The invention provides a multi-layer rubber cable. A lot of thermal energy and expensive heating devices are not needed, and crack of a coating layer is not easy. The multi-layer rubber cable (100) comprises a wire (101), an inner coating layer (102) formed at the periphery of the wire (101), and an outer coating layer (103) formed at the periphery of the inner coating layer (102). The inner coating layer (102) is prepared from halogen-containing rubber containing silane crosslinking groups. The outer coating layer (103) is formed by a material. The material is placed in a state of application of a load of 7N/cm<2> at a temperature of 40 DEG C for 24h, and the permanent deformation rate of after load release is less than 5%. |
