Problems solved by technology
[0002] Electrical control technology is of great significance in coal mine production. With the continuous improvement of coal mine mechanization and automation, unmanned operation and intelligence will be used in coal mining projects. Control cores and optical fiber units need to be added to cables. Towing photoelectric composite cables, due to the complexity of the working conditions, the cables are in a moving, dragging and bending state for a long time, so the mechanical life of the cables is very short

Embodiment 1
[0060] See figure 1 , The towing photoelectric composite cable for ground mining engineering of the present invention includes a main core 1, a monitoring core 2, a center filling 3, a control core 4, an optical cable 5, a ground core 6, a reinforcing layer 7 and an outer sheath 8.
[0061] See figure 1 , there are three main cores 1, and the three main cores 1 have the same structure, and are provided with a main core conductor 1-1, a main core insulating layer 1-2 and a shielding layer 1-3 sequentially along their respective radial directions from inside to outside.
[0062] The main core conductor 1-1 is formed by twisting and re-twisting several tinned copper wire bundles. The main core insulating layer 1-2 is made by continuous vulcanization of ethylene-propylene rubber with a hardness of 60A to 80A, and the main core insulating layer 1-2 is extruded outside the main core conductor 1-1.
[0063] See figure 1 , the shielding layer 1-3 includes a braided shielding layer ...

The invention discloses a dragging photoelectric composite cable for overground mining engineering. The dragging photoelectric composite cable is characterized by comprising a main wire core, a monitoring wire core, a center filler, control wire cores, an optical cable, a ground wire core, a reinforcing layer and an outer sheath. And the main wire core conductor is formed by stranding and re-stranding a plurality of tinned copper wires. The main wire core insulating layer is made of ethylene propylene rubber through continuous vulcanization, and the main wire core insulating layer is extrudedoutside the main wire core conductor. The shielding layer comprises a braided shielding layer and a wrapping shielding layer. And the braided shielding layer is formed by compositely braiding a strandof braided conductors serving as braided wires and nylon yarns outside the main wire core insulating layer. And the semi-conductive nylon tape is wrapped outside the braided shielding layer to form awrapped shielding layer. A saddle-shaped core pad is adopted for the center filler, and the saddle-shaped core pad is formed by extruding a semiconductive rubber or neoprene rubber material outside the monitoring wire core. And the outer sheath is extruded outside the three main wire cores, the control wire core, the optical cable, the ground wire core and the central filler which are stranded into the cable by adopting a chloroprene rubber material. The reinforcing layer is arranged in the outer sheath.
Description
technical field [0001] The invention relates to the technical field of power cables, in particular to a towed photoelectric composite cable for ground mining engineering and a production process thereof. Background technique [0002] Electrical control technology is of great significance in coal mine production. With the continuous improvement of coal mine mechanization and automation, unmanned operation and intelligence will be used in coal mining projects. Control cores and optical fiber units need to be added to cables. Towing photoelectric composite cables, due to the complexity of the working conditions, the cables are in a moving, dragging and bending state for a long time, so the mechanical life of the cables is very short. Contents of the invention [0003] The object of the present invention is to provide a drag photoelectric composite cable for ground mining engineering with simple structure and beneficial to prolong service life and its production process.
