Abstract
The invention discloses a rat-proof and ant-proof cable for a coal mine. The rat-proof and ant-proof cable for the coal mine comprises six sets of conductor wire cores, seven layers of outer protective layers and two lines of tensile steel wires. The seven layers of the outer protective layers are composed of a polyester fiber packing layer, an ethylene propylene rubber insulating layer, a tinning nickel strap armor layer, a cross linked polyethylene insulating layer, a silver-plated copper strip armor polyethylene sheath layer, a nonmagnetic metal armor layer and a tinning nickel plastic aluminium strip recombination sheath layer from inside to outside in sequence; the six sets of the conductor wire cores are evenly squeezed and wrapped between the ethylene propylene rubber insulating layer and the tinning nickel strap armor layer, each set of the conductor wire cores internally squeezes and wraps a galvanizing annealing copper wire drainage wire, and the two tensile steel wires are evenly squeezed and wrapped between the silver-plated copper strip armor polyethylene sheath layer and the nonmagnetic metal armor layer. The rat-proof and ant-proof cable has acid and alkali resistance and ageing resistance and can prevent from getting bitten from rats and ants, the cable is widely applied to coal mining sites, and the anti-tensile strength is strong.
Description
Technical field
The invention belongs to field of cables, particularly relate to a kind of colliery rat-and-ant proof cable.
Background technology
Cable has electric conductivity, be widely used in each different field, as petrochemical industry, the fields such as colliery underground metal mining, cable is normally by the cable of several or the stranded similar rope of several groups of wires [often organizing at least two], often organize mutually insulated between wire, and be often twisted into round a center, whole outside is surrounded by the cover layer of high-insulation.Multi rack is located at aerial or is contained in underground, the bottom, for telecommunication or electric power conveying.
Summary of the invention
In order to increase the practicality of prior art, the object of this invention is to provide a kind of good acid-alkali-corrosive-resisting and anti-aging of having, and the colliery rat-and-ant proof cable that rat-and-ant proof bites.
The present invention takes following technical scheme to realize: a kind of colliery rat-and-ant proof cable, it comprises six groups of conductor thread cores, seven layers of external protection and two tensile steel wire, seven layers of external protection are followed successively by polyester fiber packed layer from inside to outside, ethylene propylene rubber insulated layer, zinc-plated nickel strap armour, crosslinked polyetylene insulated layer, silver-plated copper strips armouring pe sheath layer, nonmagnetic metal armour and zinc-plated nickel mould aluminium strip composite jacket layer, polyester fiber packed layer is set to the central core of cable, conductor thread core is zinc-plated annealed copper conductor thread core, six groups of conductor thread cores are evenly extruded between ethylene propylene rubber insulated layer and zinc-plated nickel strap armour, often organize zinc-plated annealed copper conductor thread core inside and extrude ten zinc-plated annealed copper conductors, every root zinc-plated annealed copper conductors cross diameter length is 0.55 ㎜, outer wrapping one deck nickel strap screen of ten zinc-plated annealed copper conductors and the zinc-plated aluminium strip screen of one deck, described zinc-plated aluminium strip screen inside extrudes a zinc-plated annealing copper wire drainage thread, two tensile steel wire are evenly extruded between silver-plated copper strips armouring pe sheath layer and nonmagnetic metal armour, described tensile steel wire is set to silver-plated tensile steel wire.
The cross-sectional diameter length of described silver-plated tensile steel wire is 0.85 ㎜.
The present invention has following beneficial effect in sum: this kind of cable has acid-alkali-corrosive-resisting and anti-aging, and rat-and-ant proof bites, and be widely used in coal mining place and use, and pull resistance is strong.
