Abstract
The invention discloses an anti-explosion intrinsic safety armoured shield cable. The cable comprises four kinds of conductors and six outer sheath protective layers. The four kinds of conductors are respectively aluminium alloy conductors, silver plated aluminium conductors, tin plated aluminium conductors and zinc plated aluminium conductors; the six outer sheath protective layers are respectively a polyvinyl chloride (ethylene propylene) insulating layer, a silver plated annealed copper strip armouring layer, a silver plated copper strip shielding layer, a silver plated aluminium strip nickel plastic shielding layer, an aluminium plastic nickel strip composite armouring layer and an aluminium plastic armoured polyethylene sheath layer; nineteen aluminium alloy conductors are extruded in the polyvinyl chloride (ethylene propylene) insulating layer; sixteen silver plated aluminium conductors are extruded in the silver plated annealed copper strip armouring layer; twenty-four tin plated aluminium conductors are extruded in the silver plated copper strip shielding layer; and twenty-five zinc plated aluminium conductors are extruded in the silver plated aluminium strip nickel plastic shielding layer. The cable has the characteristic of low capacitance; by utilizing the reinforced shielding layer, the cable has attractive shielding property; the electric field coupling resisting property is good, the anti-freezing performance is excellent, and the cable is durable.
Description
Technical field
The invention belongs to field of cables, particularly relate to a kind of explosion-proof type intrinsic safety sheathed shielded cable.
Background technology
Cable has electric conductivity, be widely used in each different field, 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 and a kind of there is fabulous shielding properties, the explosion-proof type intrinsic safety sheathed shielded cable that the ability of anti-field coupled is good.
The present invention takes following technical scheme to realize: a kind of explosion-proof type intrinsic safety sheathed shielded cable, and it comprises four kinds of conductors and six layers of oversheath protective layer.Described four kinds of conductors are respectively aluminium alloy conductor, silver coated aluminum conductor, zinc-plated aluminium conductor and zinc-plated aluminium conductor, six layers of oversheath protective layer are respectively polychlorostyrene second propylene insulating barrier, silver-plated annealing copper strips armour, silver-plated copper strips screen, silver-plated aluminium strip nickel moulds screen, plastic-aluminum nickel strap composite armor and plastic-aluminum armouring pe sheath layer, described aluminium alloy conductor is 19 and is extruded in polychlorostyrene second propylene insulating barrier inside, described silver coated aluminum conductor is 16 and is extruded in silver-plated annealing copper strips armour inside, described zinc-plated aluminium conductor is 24 and is extruded in silver-plated copper strips screen inside, described zinc-plated aluminium conductor is 25 and is extruded in silver-plated aluminium strip nickel and moulds screen inside, the silver-plated aluminium strip nickel of outer wrapping one deck of described silver-plated copper strips screen moulds screen, described silver-plated aluminium strip nickel moulds outer wrapping one deck plastic-aluminum nickel strap composite armor of screen, outer wrapping one deck plastic-aluminum armouring pe sheath layer of described plastic-aluminum nickel strap composite armor.
