Abstract
The invention discloses a flexible rubber-sheathed cable capable of resisting salts and repeated bending, which comprises a plurality of cable cores, an elastomer composite sheath layer coated outside the cable cores and a synthetic fiber core column, wherein the cable cores are uniformly twisted on the core column; each cable core comprises a flexible tinned copper fine wire conductor formed by twisting and a silicon rubber insulating layer coated on the flexible tinned copper fine wire conductor. The synthetic fiber core column in the invention has the advantages of extremely-high strength, light weight and wide range of continuous service temperature. According to the flexible rubber-sheathed cable disclosed by the invention, a layer of silicon oil is coated on the silicon rubber insulating layer; when the cable does repeated bending motion, various parts synchronously move, and thus the bending tensile strain performance is improved and annular stress in the bending process of the cable is facilitated to be absorbed, relieved and reduced; and the service life of the cable is prolonged; meanwhile, a salt resisting layer is coated on the elastomer composite sheath layer so as to form the effect of resisting salts; and the flexible rubber-sheathed cable is especially suitable for ports and docks at seasides, ship building, logistics centers, construction projects and other industrial and mining establishments.
Description
Technical field
The present invention relates to the cable of a kind of signal monitoring or electric energy transmitting, particularly a kind of salt tolerant and anti-alternating bending rubber sleeve flexible cable.
Background technology
In the industrial and mining enterprises; Be widely used like apparatus for hoisting such as port and pier portal jib crane, drivings; Because they are in the operational environment that frequently moves back and forth, for motor cable requirement softness wherein, anti-flexural fatigue, tension, but such cable that uses at present is short general useful life; Copper conductor wherein is bent too early easily and destroys and fracture, can not adapt to the needs of production.As the service cable of electric energy transmitting, because port and pier are near the seashore, salt content is higher in the seawater; Lake surface or the seawater top cable surface that is laid in is easy to salt crust; And can tie thicker and thicker, cable be corroded in the not only corresponding deadweight that increases cable easily; And influence the cable heat radiation, finally its consequence can only reduce the useful life of the ampacity and the cable of cable conductor
Summary of the invention
Technical problem to be solved by this invention is in order to overcome above-mentioned weak point, and provide that a kind of anti-bent fatigue behaviour is good, tensile strength is high, the salt tolerant of long service life and anti-alternating bending rubber sleeve flexible cable.
Technical problem to be solved by this invention can realize through following technical scheme:
Salt tolerant and anti-alternating bending rubber sleeve flexible cable; Comprise the elastomer composite restrictive coating that some cable cores are outer with being coated on said some cable cores; It is characterized in that also comprise a synthetic fibers stem stem, said some cable cores are stranded on the said synthetic fibers stem stem in uniform way.
Each root cable core is made up of stranded zinc-plated soft copper fine rule conductor that forms and the silicone rubber insulation layer that is coated on the said zinc-plated soft copper fine rule conductor, on said silicone rubber insulation layer, is coated with one deck silicon layer.
In a preferred embodiment of the invention, on said elastomer composite restrictive coating, be coated with one deck and hate salt deposit.
The present invention is owing to adopt above architecture advances, and the synthetic fibers stem stem in the cable core has high intensity, is 5～6 times of high-quality steel; Toughness is 2 times of steel, and weight is merely 1/5 of steel, continuously the serviceability temperature wide ranges; Shrinkage is little; High temperature is difficult for down decomposing, fusing, Heat stability is good, and have good insulation performance property and corrosion resistance.Apply one deck silicone oil on the silicone rubber insulation layer of cable core; Can follow slippage when cable is crooked; Each several part is made same moved further during the operation of cable cyclic bending, more is rich in high resiliency, improves the bend tension strain property; Help absorbing, alleviating and reduce the circumference stress in the cable BENDING PROCESS, prolong cable useful life.The elastomer composite restrictive coating has mechanical performance and elasticity preferably; Coat one deck at the elastomer composite restrictive coating simultaneously and hate salt deposit; Make elastomer composite restrictive coating smooth surface such as mirror; The effect of salt is hated in formation, is particularly suitable for industrial and mining enterprises such as seashore port and pier, shipbuilding, logistics center, architectural engineering and uses.
Description of drawings
Fig. 1 is an end face structure sketch map of the present invention.
Embodiment
Combine the accompanying drawing illustrated embodiment that the present invention is made detailed description at present.
As shown in Figure 1, salt tolerant shown in the figure and anti-alternating bending rubber sleeve flexible cable comprise synthetic fibers stem stem 5, the stem stem that synthetic fibers stem stem 5 is processed for aramid fiber.Stranded in uniform way on synthetic fibers stem stem 5 have 8 cable cores, is coated with elastomer composite restrictive coating 4 at 8 cable cores, and elastomer composite restrictive coating 4 is the chlorinated polyethylene rubber restrictive coating, is coated with one deck at elastomer composite restrictive coating 4 and hates salt deposit 3.
Every cable core is restrainted the stranded conductor that forms 1 in the same way by the zinc-plated soft copper fine rule of annealing and is constituted with the silicone rubber insulation layer 2 that is coated on the zinc-plated soft copper fine rule conductor 1, on the silicone rubber insulation layer 2 of every cable core, is coated with the silicon layer 6 of one deck lubricate.
Claims (3)
1. salt tolerant and anti-alternating bending rubber sleeve flexible cable; Comprise the elastomer composite restrictive coating that some cable cores are outer with being coated on said some cable cores; It is characterized in that also comprise a synthetic fibers stem stem, said some cable cores are stranded on the said synthetic fibers stem stem in uniform way.
2. salt tolerant as claimed in claim 1 and anti-alternating bending rubber sleeve flexible cable; It is characterized in that; Each root cable core is made up of stranded zinc-plated soft copper fine rule conductor that forms and the silicone rubber insulation layer that is coated on the said zinc-plated soft copper fine rule conductor, on said silicone rubber insulation layer, is coated with one deck silicon layer.
