Said control core is formed the tinned copper wire that control line conductor 9 forms for the bundle strand by control line conductor 9, fluoroplastics 10 and second third insulation 11; Control line conductor 9 outer fluoroplastics 10 and second third insulation 11 double hyer insulations of extruding;
Said cable core extrudes haloflex mixture inner sheath 17, and braiding aramid fiber silk reinforced layer 19, extrudes haloflex mixture oversheath 20 again.
The main insulation core: core conductor 1 adopts the 5th type of tin-coated copper monofilament of national standard, forms through bundle, strand; Conductor 1 outer wrapped semi-conductive tape 2; Extrude the layer that extrudes by conductor screen 3, second third insulating barrier 4, insulation shielding 5 three-layer co-extruded moulding more outside, structure is an insulated wire cores; Behind the outer wrapped semi-conductive tape 6 of insulated wire cores, outside being wrapped in cotton yarn 8 and tinned copper wire 7 combined knittings again,, can satisfy the supply load of rated voltage 6kV and following equipment to satisfy the performance of high voltage rubber cable.
For improving the safety in operation of cable, be convenient to the Monitoring and Controlling of equipment simultaneously, the flexible 6kV opencut of the utility model except that three main insulation cores, also is provided with ground wire, pilot wire and control line with trailing cable within it; The core of ground wire, pilot wire and control line all adopts tin-coated copper tow strand to form; The gnd conductor 15 wrapped semi-conductive tapes 16 of ground core; The control line conductor 9 outer fluoroplastics 10 and second third insulation 11 double hyer insulations of extruding of control core; Add bag semi-conductive tape 14 after extruding second third insulation 13 outside the pilot wire core conductor 12 of pilot wire, satisfied the actual needs of mining machinery.
Cable core extrudes haloflex mixture inner sheath 17, braiding aramid fiber silk reinforced layer 19, extrudes haloflex mixture oversheath 20 again, strengthened the mechanical performance of cable, has strengthened the ability that cable is resisted outer damage.
The beneficial effect of the utility model and prior art comparison is; The flexible 6kV opencut of the utility model is reliable with trailing cable light in structure coincidence reason; Ground wire, pilot wire, control line are just fallen into the gap that forms between the main insulation line; The laying up diameter theoretical value that makes cable is the circumscribed gardens of three main lines after tangent in twos, the product external diameter is significantly reduced, and save a large amount of sheath materials; Reduced product cost, structure is more reliable and stable, uses more convenient; Multiple functional, cable integrates functions such as power supply, safeguard protection, control, supervision.Can satisfy the environment for use requirement of opencut, be high-quality auxiliary products large-scale, the high voltage mining machinery.
