The utility model discloses a multi-core mobile type rubber jacketed flexible cable, which comprises a cable core. A belting layer is wrapped outside the cable core. An inner sheath is extruded outside the belting layer. A braid ply is braided outside the inner sheath. An outer sheath is extruded at the outermost layer of the cable. The cable core is composed of a hollow-core pipe arranged at the center of the cable core, and a plurality of insulated wires inter-twisted at the periphery of the hollow-core pipe. The hollow-core pipe is composed of a tubular thermoplastic elastomer insulated body and an aramid yarn directly-towing structure. According to the technical scheme of the utility model, the center of the cable is provided with the aramid yarn directly-towing type PTE insulated hollow-core pipe, so that the cable can be applied in usage environments of higher requirements. Therefore, the cable is effectively improved in tensile strength, anti-compression property, anti-torsion property and mechanical stress. The cable can be frequently moved in the field or at a building site.
