Umbilical cable and preparation method thereof

The invention provides an umbilical cable and a preparation method thereof. The umbilical cable comprises a cable core; the bearing layer is coated on the periphery of the cable core; the outer protection layer is coated on the periphery of the force bearing layer; the elastic protection structure is located at the end of the umbilical cable, the elastic protection structure comprises a bearing part and an elastic supporting part, the elastic supporting part comprises an elastic supporting piece, the bearing layer with the first preset length is fixedly connected with the bearing part, and the cable core with the second preset length is installed on the elastic supporting piece and forms an elastic structure; when the umbilical cable is subjected to a mechanical load, the elastic configuration can stretch out and draw back under the mechanical load. According to the technical scheme, the umbilical cable can solve the problems that when an existing umbilical cable is applied to a large-water-depth environment,
