Abstract
The invention discloses a multi-aluminum-conductor twisted copper-strip armored cable, and the cable consists of aluminum conductors, a polyester fiber layer, a tin-coated copper wire shielding layer, a copper-strip armored layer, a polyvinyl chloride insulating layer, and a chloroprene rubber sheath layer. The cable has seven groups of conductor cores, and each group of conductor cores is formed by the twisting of 19 aluminum conductors. The exterior of the seven groups of conductor cores is wrapped by the polyester fiber layer, and the exterior of the polyester fiber layer is wrapped by the tin-coated copper wire shielding layer. The exterior of the tin-coated copper wire shielding layer is wrapped by the copper-strip armored layer, and the exterior of the copper-strip armored layer is wrapped by the polyvinyl chloride insulating layer. The cable is great in resistance to tear and tension, is high in performance of resisting acid and alkali corrosion, achieves low-smoke halogen-free flame-retardant performances, and has no poison gas during burning.
Description
Technical field
The invention belongs to field of cables, particularly relate to the stranded copper strips armoured cable of a kind of multiply aluminium conductor.
Background technology
At present, along with socioeconomic development, electric wire consumption increases rapidly, also constantly improves the quality requirement of cable, the cable such as used in the fields such as aviation, generating, metallurgy, chemical industry, to the power transmission capacity of cable, shielding properties, anti-tear drawing property, the requirement of acid-alkali-corrosive-resisting aspect is high all especially, only meet the requirements, fail safe when manufacturing in these fields could be improved.
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 tear resistance strong, the stranded copper strips armoured cable of the multiply aluminium conductor that acid-alkali-corrosive-resisting performance is good.
The present invention takes following technical scheme to realize: the stranded copper strips armoured cable of a kind of multiply aluminium conductor, it is by aluminium conductor, layer of polyester fiber, tinned copper wire screen, copper strips armour, polyvinyl chloride insulation layer and chloroprene rubber sheath layer composition, this cable has seven groups of conductor thread cores, often group conductor thread core is all twisted together by 19 aluminium conductors and forms, outer wrapping one deck layer of polyester fiber of seven groups of conductor thread cores, outer wrapping one deck tinned copper wire screen of described layer of polyester fiber, outer wrapping one deck copper strips armour of described tinned copper wire screen, outer wrapping one deck polyvinyl chloride insulation layer of described copper strips armour.
A copper metal hose is extruded with between described copper strips armour and polyvinyl chloride insulation layer.
The present invention has following beneficial effect in sum: anti-tear the drawing property of the present invention is strong, and acid-alkali-corrosive-resisting is strong, also has the feature of low-smoke non-halogen flame-retardant, blazes up without the advantage of poison gas.
Accompanying drawing explanation
Fig. 1 is cross-sectional structure schematic diagram of the present invention;
Wherein: 1, aluminium conductor; 2, layer of polyester fiber; 3, tinned copper wire screen; 4, copper strips armour; 5, polyvinyl chloride insulation layer; 6, chloroprene rubber sheath layer; 7, copper metal hose.
Embodiment
As shown in Figure 1, the stranded copper strips armoured cable of a kind of multiply aluminium conductor, it is by aluminium conductor 1, layer of polyester fiber 2, tinned copper wire screen 3, copper strips armour 4, polyvinyl chloride insulation layer 5 and chloroprene rubber sheath layer 6 form, this cable has seven groups of conductor thread cores, often group conductor thread core is all twisted together by 19 aluminium conductors 1 and forms, outer wrapping one deck layer of polyester fiber 2 of seven groups of conductor thread cores, outer wrapping one deck tinned copper wire screen 3 of described layer of polyester fiber 2, outer wrapping one deck copper strips armour 4 of described tinned copper wire screen 3, outer wrapping one deck polyvinyl chloride insulation layer 5 of described copper strips armour 4.
A copper metal hose 7 is extruded with between described copper strips armour 4 and polyvinyl chloride insulation layer 5.
This cable permission work maximum temperature is 75 DEG C; The shielding rejection coefficient of this cable is less than 0.7; Can stand to exchange 50HZ, 3.5Kv/5min voltage and not breakdown.
The above is embodiments of the invention, therefore all equivalences done according to structure, feature and the principle described in the present patent application scope change or modify, and are included in patent claim of the present invention.
