High-strength communication cable for coal mine

The utility model discloses a high-strength communication cable for a coal mine, which comprises an insulation cable core. An inner insulation protective sleeve is wrapped outside the cable core; an outer protective sleeve is wrapped outside the inner insulation protective sleeve; at least one reinforcing rib arranged longitudinally is arranged between the inner insulation protective sleeve and the outer protective sleeve; an armored shielding layer is arranged between the inner insulation protective sleeve and the outer protective sleeve; and a core body of the cable core is made by mixing and twisting a steel wire and a copper wire. The high-strength communication cable for the coal mine is capable of not only bearing frequent pulling and bending, prolonging the service life of the communication cable, but also increasing anti-interference and anti-corrosion capabilities of communication cable transmission signals. Besides, the communication cable can be directly laid inside a level and a sloping lane which
