Mobile storage battery flame-retardant cable for coal mine

The utility model provides a coal mine flame-retardant cable with a mobile storage battery. The cable comprises a cable core, a halogen-free flame-retardant wrapping layer, an armor layer and a halogen-free flame-retardant outer sheath layer which are sequentially arranged from inside to outside, the cable core comprises a plurality of fan-shaped wire cores, the fan-shaped wire cores are annularlyarranged, the centers of the fan-shaped wire cores are filled with first flame-retardant ropes, and flame-retardant pieces are arranged between the adjacent fan-shaped wire cores. According to the utility model, the fan-shaped cable cores can be relatively fixed, and mutual abrasion of the fan-shaped cable cores and looseness of the fan-shaped cable cores are prevented, so that the roundness andcompactness of the flame-retardant cable are improved, and the flame-retardant effect of the flame-retardant cable is improved. 本实用新型提出了一种移动蓄电池煤矿用阻燃电缆，包括由内到外依次设置的缆芯、无卤阻燃绕包层、铠装层和无卤阻燃外护套层，缆芯包括多个具有扇形线芯，多个扇形线芯呈环形布置，多个扇形线芯的中心填充有第一阻
