Abstract
The invention discloses an XL-ETFE (Cross-linked Ethylene Tetrafluoroethylene) cable for a heater, belonging to the technical field of a special cable for the heater. The XL-ETFE cable comprises a cable core, a metal wire woven armor layer and a sheath layer, wherein the metal wire woven armor layer is extruded outside the cable core; the sheath layer is extruded outside the metal wire woven armor layer; the cable core comprises at least two pieces of conductors and insulating layers which are extruded outside the conductors; the XL-ETFE cable is characterized in that each conductor is formed of a plurality of hot tinned copper wires or silver-plated copper wires with diameter of 0.1-0.6 mm by using regular twisting or compact twisting; each insulating layer is an irradiation cross-linked ethylene tetrafluoroethylene layer; and the sheath layer is an irradiation cross-linked ethylene tetrafluoroethylene layer. The XL-ETFE cable has the advantages of simple and rational structure, small size, light weight, superior flame retardant property, easiness in production and manufacturing, capabilities of guaranteeing the machining accuracy of the cable, greatly improving the high and low temperature resistance, chemical corrosion resistance and wear resistance of the cable and meanwhile greatly improving the tensile strength of the whole body of the cable.
Description
Technical field
The invention belongs to heater special cable technical field, be specifically related to a kind of heater XL-ETFE cable, be applicable to that the heater of special trades such as Aero-Space, satellite, guided missile connects lead.
Background technology
Cable is to be made by the conductor outsourcing insulation and the protective layer of one or more mutually insulated, can be with electric power or information from a lead that is transferred to another place.Cable of a great variety according to different purposes and job requirement, all has special structure and performance.In special trades such as Aero-Space, satellite, guided missiles, require standard higher to cable, particularly be applied to the connection cable on the heater in above-mentioned field, not only need to satisfy outside general heatproof, oil resistant, the resistance to chemical corrosion, also need enough tensile strength and anti-wear performance.
Cable on the existing heater that is used for special trades such as Aero-Space, satellite, guided missile is made of conductor, insulating barrier, metal wire knitted armour and restrictive coating etc., and all adopt polypropylene mostly, polyethylene layer and pvc sheath layer or the like.The resistance to elevated temperatures of these polypropylene, polythene material is not enough, easily because of hot mastication, expansion, even has the potential safety hazard that causes cable to open circuit.In addition, oil resistant, the resistance to chemical corrosion of pvc sheath layer are poor, and whole cable tensile strength and anti-wear performance are all not enough simultaneously.
In view of above-mentioned prior art, be necessary existing heater is improved with special cable, the applicant has done actively and effectively to explore for this reason, and technical scheme described below is based on producing under this prerequisite.
Summary of the invention
The objective of the invention is to provide a kind of heater XL-ETFE cable, it is not only simple in structure, volume is little, in light weight, fire resistance is superior, and manufacture easily, can guarantee the machining accuracy of cable, promote resistant of high or low temperature, chemical resistance, the anti-wear performance of cable greatly, also greatly improved the tensile strength of whole cable simultaneously.
The objective of the invention is to reach like this, a kind of heater XL-ETFE cable, comprise cable core, be extruded in the outer metal wire knitted armour of cable core and be extruded in the outer restrictive coating of metal wire knitted armour, described cable core comprises conductor and is extruded in the outer insulating barrier of conductor, the quantity of described conductor is at least two, be characterized in: it is regular stranded or press stranded forming that each conductor is by the complex root diameter that the hot tinning copper wire of 0.1-0.6 ㎜ or silver-gilt copper wire adopt, described insulating barrier is cross-linking radiation ethylene-tetrafluoroethylene copolymer (XLETFE) layer, and described restrictive coating is similarly cross-linking radiation ethylene-tetrafluoroethylene copolymer (XLETFE) layer.
In a specific embodiment of the present invention, the tin coating thickness of described hot tinning copper wire is 0.5～2um.
In another specific embodiment of the present invention, the silver coating thickness of described hot dip silver-bearing copper silk is 0.5～1um.
In another specific embodiment of the present invention, the twisting pitch of described conductor is 10～15 times of conductor diameter.
Also have in the specific embodiment of the present invention, the thickness of described insulating barrier is 0.15～0.5 ㎜.
In of the present invention and then specific embodiment, the thickness of described restrictive coating is 0.15～0.5 ㎜.
Conductor of the present invention can guarantee the machining accuracy of cable owing to adopted regular strandedly or press stranded hot tinning copper wire or silver-gilt copper wire; Select for use cross-linking radiation ethylene-tetrafluoroethylene copolymer material as insulating barrier and restrictive coating simultaneously, improved cable resistant of high or low temperature, chemical resistance, anti-wear performance and tensile strength; In addition, also have simple and reasonable, volume is little, in light weight, characteristics that fire resistance is superior.The experiment proved that above-mentioned cable does not ftracture after 313 ± 3 ℃ * 2H of high temperature reels, reel and do not ftracture to have excellent high temperature performance at low temperature-65 ℃ * 4H; Adhesion test: 230 ℃ ± 3 ℃ * 24h, adhesion; Smolder: 250 ℃ ± 5 ℃ * 15min, no visible smoke; High temperature is reeled: 313 ± 3 ℃ * 2h, electric wire does not have cracking.
Description of drawings
