Lightweight detection cable for long-distance transportation for underground mining

The invention relates to a light detection cable for long-distance transmission for underground mining, which belongs to the technical field of cables and comprises a conductive cable core, a cable core insulating layer coated on the outer side of the conductive cable core, a filling layer coated on the outer side of the cable core insulating layer, a shielding layer coated on the outer side of the filling layer and a sheath layer coated on the outer side of the shielding layer. The carbon nano tubes are introduced into the conductive cable core, the conductivity of the cable is greatly improved, meanwhile, flame-retardant modified composite rubber is adopted as the filling layer, after nanoscale magnesium hydroxide is grafted with polystyrene, dispersity is better, distribution in a polymer is more uniform, the flame-retardant effect is better, in addition, ethylene-tetrafluoroethylene copolymer is used as the shielding layer, and the shielding performance of the cable is improved. The density of the ethylen
