Abstract
The utility model discloses a flexible buffer protection cable, which belongs to the technical field of cables and comprises a cable core and a sheath layer. The cable is characterized in that the cable core is composed of three inter-twisted insulated conductor cores. The cable core is wrapped with a wrapping tape. The sheath layer composed of an inner layer, an interlayer and an outer layer is extruded on the outside of the wrapping tape. The inner layer is in the form of a nano conductive graphite shielding layer. The interlayer is in the form of a foaming buffer layer made of polyurethane material. The outer layer is in the form of an outer sheath layer and also made of polyurethane material. Gaps in the cable core are filled with fillings. According to the technical scheme of the utility model, when the above flexible buffer protection structure is adopted instead of the conventional metal armored structure, the weight and the cost of a cable product are reduced by 15-30% and 10-20% respectively. Meanwhile, the cable product is also lower in transportation cost, laying cost and other costs. The flexible buffer protection cable has the advantages of good flexibility and buffering performance, excellent tensile property, wear resistance and oil resistance, high safety performance, environmental protection and long service life.
Description
Technical field
The utility model relates to a kind of structure of cable, and especially a kind of structure of flexible buffer protection cable belongs to the cable technology field.
Background technology
For preventing from being subjected to mechanical damage, and be armoured cable at the cable that skin installs steel first protective layer additional.Its kind is divided into metal (as steel band, steel wire, aluminum pipe, aluminium wire etc.) or nonmetal (as aramid fiber, carbon fiber etc.) protective layer.Armouring also plays effects such as anti-electromagnetic interference, increase mechanical strength except above anti-mechanical damage.
Along with the development of cable cause, armoured cable is approved by society and user.And the form of armouring, from " armouring " as the term suggests expect mostly be metal, be confined on metal and the fiber.At present along with the development of the progressively boosting electric utility of mesohigh, extra-high-tension cable.Armouring class cable also acts in accordance with development of times.And along with the external diameter of cable increases gradually, the also corresponding increase of armouring thickness, and the weight metal of its armouring form also increases gradually, has all inevitably increased labour intensity from producing, transport, installing, and has increased cable cost.
Therefore, need to improve a kind of in light weight, produce easily, be convenient to the cable that transports and install.
The utility model content
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, and a kind of effect of both having played armouring is provided, and has satisfied anti-electromagnetic interference performance again, and flexible buffer in light weight, that produce easily, be convenient to transport and install is protected cable.
The purpose of this utility model is achieved through the following technical solutions: flexible buffer protection cable; comprise cable core, restrictive coating; it is characterized in that; described cable core thoroughly does away with stranded the forming of edge core by three; wrapped band on the cable core; the restrictive coating that coextrusion is made of internal layer, intermediate layer, skin on the band; described internal layer is conductive nano graphite shielding layer; the polyurethane foam resilient coating that make for expansion type polyurethane in described intermediate layer; described skin is the polyurethane outer jacket, and described cable core is provided with filler in the space.
Described insulated wire cores is made of extruded insulation layer on copper conductor or the tin-coated copper conductor.
Described filler is the flame retardant type filler.
Described band is the flame retardant type band.
Be provided with copper wire between described band and the restrictive coating and twine screen.
The utility model is for shielding (ground connection) type flexible buffer protection cable is arranged; the product structure of the inner sheath of three layers of replacement of anti-static shielding layer, polyurethane foam resilient coating, polyurethane outer jacket traditional cable that employing conductive nano graphite, the sparse winding combination of copper wire are made, armouring, oversheath; guarantee the anti-electromagnetic interference of cable and bonding effect, reduced cable weight.Traditional armouring class cable mostly is the rigid metal material; the very stiff and demanding phenomenon that when external impacts, produces; though mechanical strength height; but also be relative; might occur oversheath under external force damages; problems such as inner sheath damage and endothecium structure damage; and structure of the present utility model is applied to the polyurethane foam technology on the sheath technology; because the mechanical property of polyurethane material itself; except the mechanical performance that guarantees material; also has the excellent resilience of certain axial and compressibility radially and compression back; can play the effect of resilient coating; the alternative traditional armouring cable of the utility model, and the rigid protective of traditional cable changed into flexible protective.The tradition armoured cable causes bending radius to become big owing to adopt metal material as armouring, caused inconvenience to construction, and the utility model has adopted full flexible structure design, has increased the pliability of product, and Cable Bending Radius is less, has made things convenient for to install to lay.Flexible buffer of the present utility model protection structure can replace the metal armouring product, and the weight of cable product can reduce 15%～30%, and cost descends 10%～20%, and can be the product of cable transportation, lay etc. and to save cost.Because product is in light weight, and be the protection structure, can adjust the averag density of polyurethane foam degree control cable, can be designed to the suspension cable product of different depth, also widenable to the underwater protection product, have advantages such as shock resistance, hydraulic pressure.The utility model is flexible and shock-absorbing capacity is good, has extremely strong pull resistance, excellent wear-resisting, oil resistance, its security performance height, environmental protection, long service life.
