Coal cutter reinforced cable
2012
The utility model discloses a coal cutter reinforced cable. A cable core is formed by stranding an insulating power line core, a ground wire core, and a control wire core group. A netted nylon reinforced layer, is woven outside the cable core. An inner sheath is extruded outside the netted nylon reinforced layer. A bullet wire reinforced layer is winded or woven outside the inner sheath. An outermost layer of the cable is extruded with an outer sheath. The high-strength and good toughness bullet wires are used as the reinforced layer in the cable, thereby effectively offsetting shear forces and bending forces on the cable caused by frequently turning around, bending and moving excavation equipment, thereby obviously prolonging service life of the cable.
