Abstract
The invention discloses a high-temperature-resistant drag-resistant double-shielded reinforcing cable for an instrument. The cable comprises a cable core set, a tape wrapping layer, an insulating layer, a shielding layer and a protective jacket. The cable core set is formed by a main cable core, a grounding cable core, an externally wrapping skinning layer, an inner shielding layer and an inner insulating sleeve, an insulation reinforcer is arranged between the main cable core and the grounding cable core and is made of polyvinyl chloride, a steel wire rope is wrapped in the center of the polyvinyl chloride, a metal layer is wrapped in the position between the shielding layer and the protective jacket, the shielding layer is formed by a weaving layer and an aluminum foil layer, the weaving layer is formed in the mode that nickel plating aluminum wires are wrapped with steel wires, the protective jacket is made of fluoroplastics, and expanded perlite, waterproof paste and mica organosilicone are added to the fluoroplastics. The cable is good in conductivity, resistant to high temperature, oil-proof, acid-proof, widely applicable to instruments in the fields of steelworks, power plants, ships, aviation and the like, drag-resistant, high in anti-interference and firm.
Description
Technical field
The invention belongs to field of cables, relate in particular to the high temperature resistant anti-double shield that pulls of a kind of instrument and strengthen cable.
Background technology
At present, along with developing rapidly of Chinese national economy and improving constantly of living standards of the people, accelerate the growth of cable consumption, the quality requirement of cable has also constantly been improved.Such as, the cable using in the fields such as steel plant, power plant and boats and ships aviation is all very high to the each side quality requirement of cable, not only require cable will possess high temperature resistant, anti-pulling, conduct electricity very well, but also to possess anti-interference, insulation property height etc. characteristic.Only meet the requirements, just can better ensure the production and application of cable.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide a kind ofly conduct electricity very well, anti-ly pull, core is firm, the high temperature resistant anti-double shield reinforcement cable that pulls for instrument of high temperature resistant, double shield.
The present invention takes following technical scheme to realize: a kind of instrument is strengthened cable by the high temperature resistant anti-double shield that pulls, and it comprises core group, belting layer, insulating barrier, screen and protective sleeve.Described core group is made up of skinning cortex, internal shield, the insulation inner sleeve of master core, ground connection core and outsourcing; between described master core, ground connection core, be provided with insulating strength part; described reinforcement material is the polyvinyl chloride of center wrapped wire rope; coated metal layer between described screen and described protective sleeve; described screen is made up of braid and the aluminium foil layer of nickel plating aluminium wire Covered with Angles silk, and described protective sleeve material is to add expanded perlite, waterproof and the organosilyl fluoroplastics of mica.
Described metal level is for plating paper tinsel magnesium rod outsourcing ultra-fine anaerobic annealed wire, according to 36/0.20(root/millimeter) weave and form, described metal layer thickness is 3.8 millimeters.
Described belting layer inside is surrounded by three copper wire drainage threads.
The present invention has following beneficial effect in sum: this cable conduction performance is good, high temperature resistant, and oil resistant is acidproof, be widely used in the fields such as steel plant, power plant and boats and ships aviation in instrument, anti-pulling, anti-interference strong, meanwhile, core is firm, effectively prevents extraneous strong extruding.
