The cable includes cable cores, a polyester film and an external protective sleeve. The cable cores include a signal wire, power lines and a stretch resistant unit. The signal wire includes a conductor, an insulating layer and a shielding layer, wherein the insulating layer and the shielding layer are wrapped outside the conductor in order in a pressing manner. Each power line includes a power-line conductor and a power-line insulating layer, wherein the power-line insulating layer is wrapped outside the power-line conductor in a pressing manner. The polyester film and the external protective sleeve are wrapped outside the cable cores in order. The stretch resistant unit includes a stretch resistance core layer and an under layer wrapped outside the stretch resistance core layer. The beneficial effects of the low-temperature-resistant oil-resistant combination cable used for the mine are that the stretch resistant unit is added and the material of the stretch resistance core layer of the stretch resistant unit adopts aramid fiber. Because the aramid fiber is a novel high-tech synthetic fibre and has excellent properties of being ultrahigh in strength, high in modulus, high-temperature resistant, acid and alkali resistant, light in weight, insulating, aging resistant and long in life cycle and the like, the cable is long in service life and capable of adapting to a hostile environment in the pit.
