Abstract
The invention discloses a multi-conductor twisted insulating sheath cable, and the cable consists of aluminium alloy conductors, a silicone rubber insulating layer, a polyester fiber layer, a chloroprene rubber sheath layer, and a low-smoke halogen-free polyolefin sheath layer. The cable has seven groups of conductor cores, and each group of conductor cores is formed by the twisting of 19 aluminium alloy conductors. The exterior of the seven groups of conductor cores is wrapped by the silicone rubber insulating layer, and the exterior of the silicone rubber insulating layer is wrapped by the polyester fiber layer. The exterior of the polyester fiber layer is rapped by the chloroprene rubber sheath layer, and the exterior of the chloroprene rubber sheath layer is wrapped by the low-smoke halogen-free polyolefin sheath layer. The cable is good in insulating property, 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 a kind of multiply conductor strand insulating sheath cable.
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, insulation property, 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 acid-alkali-corrosive-resisting performance excellent, tear resistance is strong, the multiply conductor strand insulating sheath cable that shielding insulation performance is good.
The present invention takes following technical scheme to realize: a kind of multiply conductor strand insulating sheath cable, it is by aluminium alloy conductor, silicone rubber insulation layer, layer of polyester fiber, chloroprene rubber sheath layer and low-smoke halogen-free polyolefin restrictive coating composition, this cable has seven groups of conductor thread cores, often group conductor thread core is all twisted together by 19 aluminium alloy conductors and forms, outer wrapping one deck silicone rubber insulation layer of seven groups of conductor thread cores, outer wrapping one deck layer of polyester fiber of described silicone rubber insulation layer, outer wrapping one deck chloroprene rubber sheath layer of described layer of polyester fiber, outer wrapping one deck low-smoke halogen-free polyolefin restrictive coating of described chloroprene rubber sheath layer.
The present invention has following beneficial effect in sum: the present invention has excellent insulation property, and anti-tear drawing property 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 alloy conductor; 2, silicone rubber insulation layer; 3, layer of polyester fiber; 4, chloroprene rubber sheath layer; 5, low-smoke halogen-free polyolefin restrictive coating.
Embodiment
As shown in Figure 1, a kind of multiply conductor strand insulating sheath cable, it is by aluminium alloy conductor 1, silicone rubber insulation layer 2, layer of polyester fiber 3, chloroprene rubber sheath layer 4 and low-smoke halogen-free polyolefin restrictive coating 5 form, this cable has seven groups of conductor thread cores, often group conductor thread core is all twisted together by 19 aluminium alloy conductors 1 and forms, outer wrapping one deck silicone rubber insulation layer 2 of seven groups of conductor thread cores, outer wrapping one deck layer of polyester fiber 3 of described silicone rubber insulation layer 2, outer wrapping one deck chloroprene rubber sheath layer 4 of described layer of polyester fiber 3, outer wrapping one deck low-smoke halogen-free polyolefin restrictive coating 5 of described chloroprene rubber sheath layer 4.
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.
