Abstract
The utility model relates to an anti-strong interference and water stopping type high-speed remote signal transmission cable for coal mining, which belongs to the technical field of a cable. The utility model is composed of insulated cores composed of double layers of insulating layers lapped on a conductor by high-fire retardant, non-halogen and low-smoke polyolefin tapes and extruded on the conductor by high-fire retardant, non-halogen and low-smoke polyolefin materials. Every two insulated cores are pair-twisted into groups with different pitches, and isolating layers with polyester tapes are lapped on the groups which are twisted and made into a cable core after a screening layer is lapped by tinned copper foil. After double layers of polyester isolation tapes are wound, a total screen is longitudinally wrapped by the tinned copper foil, and an inner sheath made of water-stopping type polyolefin by squeeze is tightly wrapped on the outer side of the screening layer of the cable core. Double layers of composite water-stopping tapes are tightly lapped on the outer side of the inner sheath, and finally an outer sheath made of mixing materials of polyolefin, nanometer talcum powder and nanometer magnesium hydroxide is squeezed. The utility model has the advantages of electromagnetic interference and electrostatic interference prevention, favorable water-stopping effect, high signal-transmission speed, flame retardancy and explosion protection. The utility model meets the requirement of a signal transmitting cable for coal mining.
Description
Technical field
The utility model relates to the structure of a kind of colliery with anti-strong jamming waterproofing type two-forty distant signal transmission cable, belongs to the cable technology field.
Background technology
Along with the fast development of modernization, as the coal and mining industry of the basic industry of the energy, country constantly strengthens regulation and exploitation dynamics; Particularly in recent years, because part construction of coal mine and development management are lack of standardization, gas explosion took place repeatedly and stepped on the well accident, caused the heavy losses of property and casualties.In order to strengthen the strick precaution of the dangerous accident of colliery, according to supporting needs of particularity such as safety monitoring systems in the colliery complex environment, make the colliery of its research and development have property, require high especially the insulation of cable, pair twist, shielding, waterproof, various aspects of performance such as fire-retardant, explosion-proof with anti-strong jamming waterproofing type two-forty distant signal transmission cable.The mining signal cable used of ordinary practice was by the insulated wire cores that is surrounded by insulating barrier on the conductor in the past, many cable cores to the insulated wire cores stranding, screen and oversheath etc. constitute, be used for transducer and display controller connecting line in the down-hole, owing to be subjected to electromagnetic interference under the colliery, electrostatic interference, moist, the influence of weather and unfavorable factor such as inflammable and explosive, usually cause signaling rate and quality, proof voltage and decay resistance, waterproof and explosion-proof performance descend, and obviously descend useful life, brings for colliery security monitoring effect and safety monitoring system construction cost and be difficult to estimation effect.
Summary of the invention
The purpose of this utility model is the deficiency that exists at existing mining signal cable, by improving design, provide that a kind of antijamming capability is strong, good water-proof effect, signaling rate are fast, the colliery of flame-resistant explosion-proof type is with anti-strong jamming waterproofing type two-forty distant signal transmission cable.
The purpose of this utility model is to realize like this, colliery is with anti-strong jamming waterproofing type two-forty distant signal transmission cable, comprise the insulated wire cores that is surrounded by insulating barrier on the conductor, many cable cores to the insulated wire cores stranding, screen and oversheath, it is characterized in that being provided with a plurality of cable cores of forming cable by the insulated wire cores twisted pair wire, the line group is provided with wrapped polyester band separator and the vertical bag of zinc-plated Copper Foil screen, is provided with the double-deck polyester band separator of winding on the cable core from inside to outside successively, the total screen of zinc-plated Copper Foil of vertical bag, the waterproofing type polyolefin inner sheath that extrudes, the oversheath that the two-layer compound of twining blocks water the strap water blocking layer and extrudes.
Described insulated wire cores is the wrapped high flame resistance, low smoke halogen-free polyolefin band of elder generation on conductor, extrudes the core that double insulating layer is arranged of high flame resistance, low smoke halogen-free polyolefin CABLE MATERIALS again.Described oversheath is that polyolefin tightly is coated on the water blocking layer with the material that nanomete talc powder, nano-sized magnesium hydroxide mix.
The utility model is rational in infrastructure simple, manufactures easily, and cost is low, and serviceability is good.Conductor is provided with double hyer insulation, and two eradication edge cores are stranded to be the line group, wrapped polyester band separator and zinc-plated Copper Foil screen on the line group; Double-deck polyester band separator, total screen, water blocking layer and interior oversheath are arranged on the cable core.Guarantee the anti-electromagnetic interference of cable, electrostatic interference, good water-proof effect, signaling rate is fast, and flame-proof explosion-proof satisfies the requirement of colliery with signal-transmitting cable, and the excellent popularization using value is arranged.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1 conductor, 2 double insulating layers, 3 separators, 4 screens, 5 double-deck polyester band separators, 6 total screens, 7 inner sheaths, 8 water blocking layers, 9 oversheaths.
Embodiment
The wrapped high flame resistance, low smoke halogen-free polyolefin band of elder generation extrudes the core that high flame resistance, low smoke halogen-free polyolefin CABLE MATERIALS constitutes double insulating layer 2 again on conductor 1.Per two thoroughly do away with the edge cores to being twisted into the line group, carry out stranding behind wrapped polyester band separator 3 and the zinc-plated Copper Foil screen 4 of vertical bag on online group.Twine double-deck polyester band separator 5 on the cable core from inside to outside earlier, the total screen 6 of the vertical zinc-plated Copper Foil of bag on separator 5, after extruding waterproofing type polyolefin inner sheath 7 on total screen 6, twine the two-layer compound strap water blocking layer 8 that blocks water again, at last the composite material with polyolefin and nanomete talc powder, nano-sized magnesium hydroxide extrudes oversheath 9, makes oversheath tightly be coated on water blocking layer.
