Abstract
The invention relates to a cable, in particular to a fiber-reinforced thin-wall high-strength multicore cable. The thin-wall high strength multicore cable comprises conductors, an insulation layer and a sheath. The cable also comprises high-strength high-modulus ultrahigh molecular weight polyethylene fibers; a plurality of polyethylene fibers and a plurality of thin conductors are twisted together; the twisted polyethylene fibers and thin conductors are extruded and coated by the insulation layer to form a core conducting wire; and a plurality of the core conducting wires are extruded and coated by the sheath. The material of the insulation layer is high-strength flame retardant polypropylene the insulation grade of which is 105 DEG C. The material of the sheath is flame retardant polyvinyl chloride the insulation grade of which is 105 DEG C. Through increasing the polyethylene fibers between the conductors and adopting high-grade insulation materials, the weight of the cable is reduced while the strength and the tensile property of the cable are improved, and the cable has good mechanical property and insulation grade.
Description
Technical field
The present invention relates to a kind of cable, especially fibre-reinforced thin-wall high intensity multi-core cable, this cable are applicable to the demanding control cable of tensile strength.
Background technology
At present, control device connects the common multicore cable of the general employing of control cable that the Be Controlled thing is used.Common multi-core cable structure is: be extruded with a layer insulating on some conductors, form a core lead, some core leads are formed a branch of, and the outside extrudes sheath again.This multicore cable is owing to will guarantee the class of insulation, and the thickness of its insulating barrier and restrictive coating is thicker, and the weight of cable is heavier.The class of insulation of common multicore cable is lower in addition, is generally 70 ℃, can not be high temperature resistant, and service condition is restricted.Thing moves if control cable is applied to Be Controlled, and its weight and tensile strength to control cable is had higher requirement.
Summary of the invention
The object of the present invention is to provide a kind of thin-wall high intensity multi-core cable, this cable is by increasing polyethylene fibre and adopting high-grade insulating material between conductor, make cable when improving intensity and anti-opening property, reduce weight, and have the favorable mechanical performance and the class of insulation.
The present invention is achieved in that a kind of thin-wall high intensity multi-core cable, comprise conductor, insulating barrier and sheath, described cable also comprises high-strength and high-modulus ultrahigh molecular weight polyethylene fibre, many thin conductors of many polyethylene fiber peacekeepings kink together, the outside extruded insulation layer of the thin conductor of polyethylene fiber peacekeeping after kinking forms a core lead, and some core leads are formed outside, a branch of back and extruded sheath again.
Described thickness of insulating layer is 0.20～0.30mm, and its material is the high-strength anti-flaming polypropylene, and this polyacrylic class of insulation is 105 ℃.
Described jacket thickness is 0.40～0.60mm, and its material is a flame-proof polyvinyl chloride, and the class of insulation of this polyvinyl chloride is 105 ℃.
The hot strength of described high-strength and high-modulus ultrahigh molecular weight polyethylene fibre is 2800～3500MPa, and modulus of elasticity is 85000～105000MPa, and molecular weight is 2,000,000～6,000,000.
The present invention has following beneficial effect: thin-wall high intensity multi-core cable of the present invention adds high-strength and high-modulus ultrahigh molecular weight polyethylene fibre, both attenuate insulating barrier and jacket thickness make cable weight saving, the intensity and anti-the opening property of cable have been improved again, this multicore cable adopts the high-strength anti-flaming polypropylene as insulating barrier simultaneously, adopt flame-proof polyvinyl chloride as sheath, cable can be used under-40 ℃ to 105 ℃ environment, have the favorable mechanical performance and the class of insulation, and fire-retardant, improved fail safe.
Description of drawings
The invention will be further described below in conjunction with the drawings and specific embodiments.
Fig. 1 is a thin-wall high intensity multi-core cable schematic cross-section of the present invention;
Among the figure: 1 insulating barrier, 2 conductors, 3 polyethylene fibres, 4 sheaths.
Embodiment
Referring to Fig. 1, a kind of thin-wall high intensity multi-core cable, comprise conductor 2, polyethylene fibre 3, insulating barrier 1 and sheath 4, polyethylene fibre 3 is a high-strength and high-modulus ultrahigh molecular weight polyethylene fibre, many polyethylene fibres 3 kink with the thin conductor 2 of Duo Gen is in the same place, polyethylene fibre 3 after kinking and thin conductor 2 outside extruded insulation layers 1 form a core lead, and some core leads are formed outside, a branch of back and extruded sheath 4 again.Insulating barrier 1 material is the high-strength anti-flaming polypropylene, and this polyacrylic class of insulation is 105 ℃.Sheath 4 materials are flame-proof polyvinyl chloride, and the class of insulation of this polyvinyl chloride is 105 ℃.The material of insulating barrier 1 and sheath 4 has the characteristics of class of insulation height, thin thickness.
Thin-wall high intensity multi-core cable of the present invention kinks polyethylene fibre 3 on conductor 2, because polyethylene fibre 3 has high strength and high-modulus, improved cable intensity and anti-opening property in attenuate insulating barrier 1 and sheath 4 thickness, thereby alleviated cable weight; Simultaneously this multicore cable adopt polypropylene flame redardant as insulating barrier, flame-proof polyvinyl chloride as sheath, cable can be used under-40 ℃ to 105 ℃ environment, have the favorable mechanical performance and the class of insulation, and it is fire-retardant, improved fail safe, applicable to the control cable of the shield door of track traffic.
