Problems solved by technology

Due to frequent bending, coal stamping, various mechanical extrusion, stretching and other stresses during the operation of the cable, it is easy to cause the conductive core in the control line to break. Once the conductive core breaks, it will lose the monitoring and protection function. , causing the equipment to stop rotating, seriously affecting normal production and causing great ec...

Abstract

The invention provides a shielding rubber-jacketed flexible cable for a coal cutter. The shielding rubber-jacketed flexible cable comprises power line cores, a control line core, a ground wire core, wrapping tape and an outer sheath. Each power line core comprises a power line core conductor and a power line core insulation body wrapping the power line core conductor in an extrusion mode, and insulated shielding layers wrap the power line core insulation bodies in an extrusion mode. A control line core conductor is an electricity-conducting wire core composed of mild steel wires or aramid fiber yarn, and a knitted copper braided wire outside the core is reinforced. The cable has the advantages of being high in strength, stretchability and wear resistance, being resistant to oil and heat, protecting the environment, and the like.

Description

technical field [0001] The invention relates to a cable, in particular to a shielded rubber-sheathed flexible cable for a coal mining machine. Background technique [0002] The control line in the shearer cable mainly plays the role of signal monitoring. The core of the control cable in the traditional shearer cable adopts a bundle twisted structure. Due to frequent bending, coal stamping, various mechanical extrusion, stretching and other stresses during the operation of the cable, it is easy to cause the conductive core in the control line to break. Once the conductive core breaks, it will lose the monitoring and protection function. , causing the equipment to stop rotating, seriously affecting normal production and causing great economic losses. In addition, the sheath neoprene or chlorinated polyethylene rubber compound in the traditional shearer cable contains not only halogens, but also heavy metals such as lead and cadmium, which will generate a large amount of corr...
