Abstract

The utility model discloses a corrosion-resistant and flame-retardant cable. The cable comprises conductors, insulation layers and an outer sheath. Each conductor is externally provided with one corresponding insulation layer through extrusion, so that the conductor and the insulation layer can form an insulation wire core through extrusion; two insulation wire cores are twisted, and two edge gaps are filled with one filling bar respectively, one tensile-resistant fiber rope being externally provided with an elastic material through extrusion so as to form the filling bar; three sets of twisted pairs are twisted so as to form a cable core; three edge gaps are respectively filled with one filling bar, three tensile-resistant fiber ropes being externally provided with an elastic insulation material through extrusion to form the filling bar; the cable core is externally provided with a wrapping tape through extrusion; the wrapping tape is externally provided with a copper wire shielding layer through braiding; and the copper wire shielding layer is externally provided with the polyurethane outer sheath through extrusion. The cable is advantages in excellent wear resistance and bending resistance, high conductivity and the like.

Description

A kind of corrosion-resistant flame retardant type cable

Technical field

The present invention relates to field of cables, particularly relate to a kind of corrosion-resistant flame retardant type cable。

Background technology

In current commercial production, the development of automatization is maked rapid progress。Functions of the equipments develop to multifunctional integrated direction, and the information transmission between equipment components needs the support of drag chain technology。Cable-pulling chain technical development, it is possible to realize the fully automation of equipment manufacture, is developed to FMC, CIM, CIMS by single plane automation, improves machining accuracy, efficiency, reduces and manufacture finished product。The high-tech such as the production of Digit Control Machine Tool, machining center, automated machine, robot are widely applied in processing, package system, logistic production line, the fast development of science and technology has benefited from electromechanical integration technology and combines closely, while cable carries the electric power transmission between connection running device, signal control, also need to move back and forth, play safety and the effect of guiding, in this case, because the fault of cable result in production, break occurs repeatedly, causes very big loss to manufacturer。This use is novel provide special carry out moving back and forth with drag chain and the nonabradable drag chain cable with performances such as hypervelocity softness, low temperature flexibility be good, the damage of wearability, mechanical resistant, oil resistant, acid and alkali resistances, meet the movement equipment demand to high performance cable。

Summary of the invention

In order to overcome the defect of above-mentioned prior art, it is an object of the invention to provide a kind of corrosion-resistant flame retardant type cable。

The present invention takes techniques below scheme to realize: corrosion-resistant flame retardant type cable, it is characterised in that: it includes conductor, insulating barrier and oversheath, extrudes the insulating barrier on described conductor outside described conductor；Described conductor and insulating barrier extrude composition insulated wire cores；Described two insulated wire cores groups strand is incorporated in gap place, both sides and respectively fills one by the packing extruding elastomeric material outside a traction-resistant fibre rope；Described three groups of twisted pair wire groups are twisted into cable core, and gap place, three limits respectively fill one by 3 traction-resistant fibre ropes outside extrude the packing of elastomeric insulating material；It is extruded with band outside described cable core；One layer of brass wire shielding is woven outside described band；Polyurethane oversheath is extruded outside described shielding layer of copper wires, described insulating barrier is elastic body insulated layer, described packing is the packing extruding elastomeric material composition outside traction-resistant fibre rope, and described band is slim polyester belt, and described screen layer is thin copper wire braid shielded。

The method have the advantages that this cable has good anti-wear performance, resist bending performance and conductivity advantages of higher in sum, also there is the performances such as hypervelocity softness, wearability, mechanical resistant damage, oil resistant and acid and alkali-resistance simultaneously。

Wherein: 1, conductor, 2. insulating barrier, 3. packing, 4. band, 5. woven shield, 6. oversheath。

Detailed description of the invention

As it is shown in figure 1, the corrosion-resistant flame retardant type cable of the present invention, adopt and extrude elastic body insulated layer 2 outside 6 class soft copper conductors 1；Cable is made to have good pliability and elasticity, so that cable has longer service life；Packing 3 is filled at described core group strand and gap place, stranding limit, stranded lay ratio when group strand and stranding is 6～8 times, to meet in cable laying installation process the requirement to bending radius, the packing 3 extruding elastomeric insulating material outside by traction-resistant fibre rope is filled, it is ensured that the rounding of cable at gap place, limit；The polyester belt 4 that cable core outer cladding is slim；One layer of woven shield 5 is woven outside band；Polyurethane oversheath 6 is extruded outside woven shield 5, the excellent performances such as this bi-material has superelevation pliability, wearability, resistance to indentation, resistance to cutting, low sticks, oil resistant and chemical resistance, it is possible to make cable possess and bigger use space, higher service efficiency and longer service life。

The above is the embodiment of the present invention, therefore all equivalences done according to the structure described in the present patent application scope, feature and principle change or modify, and are all included within the scope of present patent application。
