Abstract
The invention discloses a two-core pair-twisted special cable. The two-core pair-twisted special cable comprises main cable cores, a wrapping tape layer, waterproof layers, a shielding layer and a protective sleeve, wherein the number of the main cable cores is three, each main cable core is formed by twisting two tinned insulating cable cores in pairs, a reinforcing plate is arranged in the wrapping tape layer, the cross section of the reinforcing plate is formed by intersecting three insulating plates at one end, the wrapping tape layer is evenly divided into three window grids, the main cable cores are located inside the three window grids respectively, and a metal layer is arranged between the shielding layer and the protective sleeve. The two-core pair-twisted special cable is good in electricity conductivity, long in service life, resistant to high temperature, fireproof, resistant to oil, resistant to corrosion, waterproof, resistant to oxidation, high in shielding performance and resistant to dragging, and is mainly applied to the fields of computers, communication, electricity generation, chemical engineering petroleum and the like, and the cable cores are firm.
Description
Technical field
The invention belongs to field of cables, relate in particular to a kind of two core pair twist special cables.
Background technology
At present, along with developing rapidly and the raising day by day of scientific and technological level of Chinese national economy, accelerate the growth of cable consumption, equally the quality requirement of cable has also constantly been improved.The cable using in the fields such as computer, communication, generating, chemical petroleum, to the fire resistant of cable, shielding insulation performance, the requirement of the aspects such as waterproof oil resistant is all high especially.But present general cable exists, shielding properties is not high, anti-pulls a series of problems such as strong, core is firm not, waterproof is inadequate.Only meet the requirements, the fail safe could improve production and application in these fields time.
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 of good conductivity, anti-pulling, two core pair twist special cables of the advantage such as core is firm, and fire resistant is strong, and shielding insulation performance is excellent, waterproof oil resistant.
The present invention takes following technical scheme to realize: a kind of two core pair twist special cables, it comprises master core, belting layer, watertight composition, screen and protective sleeve, described master core is three groups, described master core is to be formed by two zinc-plated insulated wire cores pair twists, described zinc-plated insulated wire cores is by fine copper inner wire, the outer conductor composition of interior skinning cortex and the braiding of albronze silk, described belting layer inside is provided with a stiffener, described stiffener cross section intersects at one end by three eradication listriums and forms, described belting layer is divided into three panes, described master core lays respectively at three pane inside, between described screen and described protective sleeve, be provided with metal level.
Described screen is made up of the crosslinked outer shielding layer of internal shield, and described internal shield is to hold silicon rubber braiding by nickel-clad copper aluminum-alloy wire to form, and described outer shielding layer is to be formed by the anaerobic outer aluminium foil braiding of zinc-plated fine steel wire of annealing.
Described protective sleeve is to be made up of the pvc material that adds organic silicon ribbon, ceramic fibre, fluorescent glue.
Described stiffener is made up of the center outsourcing polyurethane of the zinc-plated ultra-fine soft proof copper-wire braided of multiply high strength 99.99% anaerobic annealing.
The present invention has following beneficial effect in sum: this cable conduction is good, long service life, fire resistant, oil resistance anticorrosion erosion, is mainly used in the fields such as computer, communication, generating, chemical petroleum, waterproof is anti-oxidant, shielding properties is strong, anti-pulling, simultaneously, cable core is firm, core can effectively resist extraneous push, pull etc. do not depart from former desired location.
