Abstract
The utility model discloses a durable cable, comprising an insulating outer protection sleeve and a plurality of conductor cable cores disposed in the insulating outer protection sleeve. Each conductor cable core is wrapped by an insulating inner protection sleeve. A shielding layer is disposed between the insulating outer protection sleeve and the insulating inner protection sleeve. Each conductor cable core is winded by at least three conductors in a weaving manner. Reinforcement cores are disposed in the insulating inner protection sleeves. The reinforcement cores are aramid fiber bundles. Tensile property and flexibility of the durable cable are improved, and the cable cores can be extended, thereby ensuring the cable cores would not break when the cable moves repeatedly, bends, winds, and flexibly stretches in a power-on operating state, so service life of the cable is improved.
Description
Technical field
The utility model relates to a kind of cable, especially relates to a kind of durable cable.
Background technology
, industrial automation flourishing at the manufacturing industry height flourish today, the direction that the variation in market, the replacement of technology are not all affecting industrial automation and advance all the time.And user demand and the use habit of relying on the user, the main flow that is fit to field movable equipment and has become undoubtedly numerous industrial automation supplier is selected.
In the face of the service condition in all parts of the country such as the north of China's severe cold, damp and hot south and the great Northwest of temperature difference drastic change drying and environment not only badly but also harsh, weather conditions are changeable, the landforms variation abnormality, Marsh Wetland, hard rock ground or desert are arranged, therefore the product of automation equipment is applied widely, and this just requires, and matching used cable can (temperature be one 50 ℃ one 70 ℃ at full weather conditions; Relative humidity is 95% ± 3%) under carry out rapidly take-up and unwrapping wire, lay and work, guarantee the safe transmission of circuit.Therefore, for above-mentioned particular surroundings requirement, a kind of tension, wear-resisting, withstand voltage and shock-resistant, lightweight, soft is provided, especially to have fabulous Flexural fatigue, with adapt to frequently, retractable line rapidly, and oil resistant, anti-ozone, corrosion-resistant, the cable new product prospect of high flame retardant characteristic will be very wide.
The utility model content
Technical problem to be solved in the utility model is: a kind of durable cable is provided, pull resistance and pliability have been improved, can make again core realize elongation, guarantee cable repeatedly move, crooked, reel and deflect the continuous core of cable under the energising running status of stretching, thereby the useful life of improving cable.
For solving the problems of the technologies described above; the technical solution of the utility model is: a kind of durable cable; comprise the insulation outer jointing jacket; be provided with some conductor thread cores in described insulation outer jointing jacket; described every conductor thread core is by an insulation internal protective cover parcel; be provided with screen between described insulation outer jointing jacket and insulation internal protective cover parcel; described every conductor thread core is formed with the weaving manner coiling by at least three wires; be equipped with strengthening core in all described insulation internal protective covers, described strengthening core is the aramid fiber bundle.
Preferably, be provided with filler between described screen and insulation internal protective cover.
Preferably, described filler is unvulcanized natural rubber.
Preferably, described insulation internal protective cover is that polyethylene is made.
Preferably, described insulation outer jointing jacket is that polyvinyl chloride is made.
Adopted technique scheme, the beneficial effects of the utility model are: the utility model is applicable to repeatedly move, crooked, reel and deflect stretching, be equipped with strengthening core in the insulation internal protective cover, to improve the tensile property of conductor thread core; Conductor thread core adopts weaving manner, has both improved the pliability of core, can make again core realize elongation, guarantee cable repeatedly move, crooked, reel and deflect under the energising running status of stretching, the continuous core of cable, thereby the useful life of improving cable.
