The utility model discloses a water-blocking, high-strength, tensile-resistant and wear-resistant shield machine cable. The cable core is twisted into a cable by insulating power cores, ground cores, and control cores. The gap between the cable cores is filled with water-blocking yarn. The cable core is wrapped with a water-blocking tape layer and extruded with an outer sheath, and the outer sheath is a polyether polyurethane outer sheath layer. , the structure of the cable has a long service life, which can meet the requirements of the safety performance and life of the cable under the complex working conditions of the shield machine.
Description
Technical field:
The utility model relates to a kind of cable, and particularly a kind of wear-resisting shield machine of high strength tension with water stop function is used cable, belongs to the electrical equipment connection and uses the cable technical field.
Background technology:
Along with the progress of science and technology, a kind of extensive utilization of novel subterranean tunnel excavating equipment shield machine has driven the widespread demand of shield machine cable.Shield machine is abominable with the environment for use of cable; Cable is often not only wanted crooked moving; Also often place grit muddy water to soak; In use cable not only will bear the crooked pulling force of powerful mechanical shearing that shield machine digging moving process produces, and hard thing extruding such as the grit rock around also receiving and muddy water soak, so cable very easily damages.Apply to shield machine on the domestic market at present and use cable, the shield machine cable that possesses the wear-resisting long life of the tension of blocking water simultaneously is few, can not satisfy market to the great demand of shield machine with cable.
Summary of the invention:
For overcoming the defective of prior art, the purpose of the utility model is to provide a kind of wear-resisting shield machine of high strength tension that blocks water to use cable, and this structural cable long service life can satisfy under the complicated working condition of shield machine the requirement to cable security performance and life-span.
The utility model technical solution problem adopts following technical scheme:
A kind of wear-resisting shield machine of high strength tension that blocks water is used cable; Cable conductor by insulation power core, core, control core be twisted into cable; Water blocking yarn is filled in the cable core gap, and said cable core is surrounded with the belting layer that blocks water outward, is extruded with oversheath, and said oversheath is the EU external sheath layer.
The conductor of said insulation power core is stranded in the same way by six types of tin-coated copper conductors and aramid fiber, and the conductor wire harness is provided with semiconductive shielding layer outward successively, EPDM rubber insulating barrier, insulated non-metal screen and metal screen layer.
The conductor of said control core is by six types of tinned conductors and aramid fiber is stranded forms; The conductor wire harness is provided with EPDM rubber insulating barrier outward successively; Water blocking yarn is filled in the cable core gap, outer wrapped belting layer and the oversheath of blocking water of cable core, and described oversheath adopts EU.
The conductor of said ground core is by six types of stranded forming of tinned conductor, and conductor is outside equipped with semiconductive shielding layer.
Compared with present technology, the beneficial effect of the utility model is embodied in:
Insulating, power core and control line core conductor adopt six types of tin-coated copper conductors and aramid fiber is stranded forms; Conductor more softness and conductor bears stretching resistance and obviously improves; Water blocking yarn and the outer wrapped band that blocks water of cable core are filled in the cable core gap; Make cable possess water stop function, oversheath adopts EU, obviously improves the tension anti-wear performance of cable.The utility model structural design, long service life can satisfy under the complicated working condition of shield machine the requirement to cable security performance and life-span.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Label among the figure: 1 insulation power core, 2 aramid fibers, 3 six types of tin-coated copper conductors, 4 semiconductive shielding layers; 5 EPDM rubber insulating barriers, 6 insulated non-metal screens, 7 metal screen layers, 8 ground cores; 9 water blocking yarns, 10 control cores, 11 belting layers that block water, 12 oversheaths.
Below pass through embodiment, and combine accompanying drawing that the utility model is described further.
Embodiment:
Embodiment: 1, a kind of wear-resisting shield machine of high strength tension that blocks water is used cable, is twisted into cable core by three insulated power cores 1, ground core 8, a control core 10, and water blocking yarn 9 is filled in the cable core gap; The outer wrapped belting layer 11 that blocks water of cable core; Outermost layer extrudes EU oversheath 12, and ground core 8 is placed in the middle of the cable core, purpose is set like this ground core is fully contacted with insulation power core; Can also effectively reduce the outside diameter of cable, improve the bending property of cable.
In specifically being provided with; The conductor of insulation power core 1 is stranded in the same way by 6 types of tin-coated copper conductors 3 and aramid fiber 2; The conductor wire harness is provided with semiconductive shielding layer 4 outward successively, EPDM rubber insulating barrier 5, insulated non-metal screen 6 and metal screen layer 7; Insulation power line core conductor screen, insulating barrier and insulated non-metal screen adopt three layers of co-extrusion, and such purpose can effectively improve the electric property of cable.
The conductor of control core 10 is by six types of tinned conductors 3 and aramid fiber 2 stranded forming; Conductor wire harness peripheral hardware has EPDM rubber insulating barrier 5, and water blocking yarn 9 is filled in the cable core gap, the outer wrapped belting layer 11 that blocks water of cable core; Cable core extrudes oversheath 12 outward, and jacket material is the EU material.
The conductor of ground core 8 is by six types of tinned conductors, 3 stranded forming, and conductor is outside equipped with semiconductive shielding layer 4.
