Abstract
The invention provides a highly flexible non-twisting control cable, and belongs to the technical field of cables. The cable comprises a left and right bi-directionally twisted cable core; a foamed polyethylene buffer layer is externally extruded and covered on the cable core, a tin-plated copper band shielding layer wraps the foamed polyethylene buffer layer, and an external protection layer is externally extruded and covered on the tin-plated copper band shielding layer; the cable core comprises four groups of wire cores, filling materials and a PP lapping band, wherein the PP lapping band wraps the four groups of wire cores and the filling materials; and the cable core also comprises a conductor and a crosslinking polyethylene insulation layer externally extruded and covered on the conductor. The cable has the advantages of high electric performance, shielding performance, mechanical properties such as tensile property and twisting resistance, thermal resistance and ageing resistance, environmental resistance, chemical corrosion resistance and fire resistance, convenient use, no limitation of laying drop heights and the like; and the cable can be laid in fixed places, such as rooms, tunnels, cable trenches and tubes, where the shielding requirements are high, and the cable can be widely used and has better social and economic benefits.
Description
Technical field
The present invention relates to a kind of highly flexible non-twisting control cable structure, belong to the cable technology field.
Background technology
At present, along with the high speed development of China's industry, the electric automatization degree is in the popularization and application of every profession and trade.Traditional cable all adopts a kind of strand to---dextrad when stranding basically, and this cable is because core closely twists together entirely, and when cable work, it was in bad order to dispel the heat, the ampacity decline of cable, thus influence the electric conductivity and the running quality of cable.
Summary of the invention
In order to overcome the deficiency of existing cable at aspects such as non-twisting, tension and shielding propertiess, the invention provides a kind of antitorque, corrosion-resistant, ageing-resistant, the highly flexible non-twisting control cable of shielding properties and satisfactory mechanical property.
The object of the present invention is achieved like this, highly flexible non-twisting control cable comprises the two-way stranded cable core in the left and right sides, and described cable core extrudes the polyethylene foamed resilient coating outward, the outer wrapped zinc-plated copper strips screen of polyethylene foamed resilient coating, zinc-plated copper strips screen extrudes outer jacket outward; Described cable core comprises four groups of cores, inserts and PP twining package tape, the wrapped periphery at four groups of cores and inserts of PP twining package tape; Described every group of core comprises conductor respectively and is extruded in the outer crosslinked polyetylene insulated layer of conductor.
In view of the deficiency of traditional cable, the present invention adopts soft junction structure conductor and the two-way strand of stranding, makes the core structure no longer so tight, thereby has improved the radiating effect of cable, and this has good flexibility and non-twisting performance.On the special equipment, pitch and stranded power in accordance with regulations, disposable whole piece completes.Thisly be stranded on pitch and the uniformity all to be consistent, pitch variation or degree of tightness non-uniform phenomenon can not occur.Employing extrudes the mechanical performance that the polyethylene foamed resilient coating strengthens cable.Oversheath adopts quality cables material such as flame-proof PVC or low smoke and zero halogen, has high flame retardant and environmental-protecting performance.Broad market prospect.
Conductor is the oxygen-free copper conductor, adopts 5 classes or 6 class soft junction structures.Insulating layer material is the XLPE cable material, and lapping layer is PP, and cushioning layer material is for extruding polyethylene foamed.Described polymeric barrier layer materials is zinc-plated copper strips shielding.Described outer sheath material adopts flame-proof PVC or polyolefin.The combination ideally of maturation process and quality material makes cable that good electrical properties, shielding properties and mechanical performance be arranged, thereby makes cable have good electrical conductivity, good noiseproof feature and the non-twisting characteristic of tension.
The present invention's tube rational in infrastructure is single, manufactures easily.Advantage such as dielectric loss is little, transmittability is strong, good in anti-interference performance, tension are non-twisting, can be widely used in important economic departments such as various industrial and mining enterprises, communications and transportation, as enterprises such as power plant, transformer station, power circuit and petrochemical industries, aspect safe power supply and production system, its function even surpass the power cable of backbone.Along with the raising day by day of automaticity in the industrial and agricultural production, the consumption of this series products will be more and more many.
According to user's needs, in the described zinc-plated copper strips screen seven copper wire drainage threads are set in addition, my company adopts in the zinc-plated copper strips shielding to add seven copper wire flow guiding structures on this novel cable basis, for suppress High-frequency Interference, static discharges and is highly profitable.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
Among the figure: 1, core; The 1-1 conductor; The crosslinked polyetylene insulated layer of 1-2; 2, inserts; 3, PP twining package tape; 4, polyethylene foamed resilient coating; 5, zinc-plated copper strips screen; 6, copper wire drainage thread; 7,8, outer jacket.
Embodiment
As shown in Figure 1, being highly flexible non-twisting control cable, is to comprise the two-way stranded cable core in the left and right sides, and cable core comprises four groups of cores 1, inserts 2 and PP twining package tape 3, PP twining package tape 3 wrapped peripheries at four groups of cores 1 and inserts 2.Every group of core 1 is made up of the copper wire stranded conductor 1-1 crosslinked polyetylene insulated layer 1-2 outer with being extruded in conductor 1-1 respectively.Cable core extrudes polyethylene foamed resilient coating 4 outward, and polyethylene foamed resilient coating 4 outer wrapped zinc-plated copper strips screens 5 are provided with seven copper wire drainage threads 6 in the zinc-plated copper strips screen 5, the zinc-plated copper strips screen 5 outer outer jackets 7 that extrude.
