The invention relates to a coal machine cable, which is formed by three copper conductive wire cores (4); insulate layer, control wire core (1) and rubber muffle, wherein the control wire core (1) is covered by insulated layer while the middle is polyester band; the control wire core (1) uses composite structure, whose center is beamed and screwed into screw copper conductor; the outer layer is high-carbon steel weave layer (2), and packed with ethylen-propylene rubber insulated layer (3); the control wire core (1) and three copper wire cores (4) form cable core; said cable core is packed with muffle (10); since it uses high-carbon steel weave layer, the anti-bend ability and anti-drawing ability of control wire core are improved, to avoid breakage. |
