Abstract
The invention discloses an anti-explosion intrinsic safety multi-layer insulated cable. The cable comprises three kinds of conductors and six outer sheath protective layers. The three kinds of conductors are respectively zinc plated aluminium conductors, tin plated nickel conductors and silver plated copper conductors; the six outer sheath protective layers are respectively an ethylene propylene rubber insulating layer, a chloroprene rubber insulating layer, a silicon rubber insulating layer, a silver plated aluminium alloy strip armouring layer, an aluminium plastic nickel strip combined armouring layer and a copper plastic composite membrane belting sheath layer; ten zinc plated aluminium conductors are extruded in the ethylene propylene rubber insulating layer; forty tin plated nickel conductors are extruded in the chloroprene rubber insulating layer, and twenty-five silver plated copper conductors are extruded in the silicon rubber insulating layer. The cable has the characteristic of low capacitance; by utilizing the reinforced insulating layer, the cable has attractive insulating 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 Multi-layer insulated 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 are fabulous insulation property, the explosion-proof type intrinsic safety Multi-layer insulated 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 Multi-layer insulated cable, it comprises zinc-plated aluminium conductor, zinc-plated nickel conductor, silver-plated copper conductor and six layers of oversheath protective layer, six layers of oversheath protective layer are respectively ethylene propylene rubber insulated layer, neoprene insulating barrier, silicone rubber insulation layer, silver coated aluminum alloy strip armour, plastic-aluminum nickel strap composite armor and copper mould composite membrane band restrictive coating, described zinc-plated aluminium conductor is 10 and is extruded in ethylene propylene rubber insulated layer inside, described zinc-plated nickel conductor is 40 and is extruded in neoprene insulating barrier inside, described silver-plated copper conductor is 25 and is extruded in silicone rubber insulation layer inside, outer wrapping one deck silver coated aluminum alloy strip armour of described silicone rubber insulation layer, outer wrapping one deck plastic-aluminum nickel strap composite armor of described silver coated aluminum alloy strip armour, outer wrapping one deck copper of described plastic-aluminum nickel strap composite armor moulds composite membrane band restrictive coating.
The present invention has following beneficial effect in sum: this kind of cable has the feature of low electric capacity, owing to have employed reinforced insulation layer, makes it have fabulous insulation property, and the ability of anti-field coupled is good, and anti-freezing property is excellent, durable in use.
