Abstract
The invention relates to a high strength corrosion resisting coaxial cable, which comprises an inner conductor, an insulating layer, an outer conductor and a sheath layer arranged from inside to outside, the insulating layer comprises an internal insulating layer and an external insulating layer, a polyester film layer is provided between the internal insulating layer and the external insulating layer; a plurality of steel wire cord threads can be provided in the polyester film layer, and the sheath layer is a polyurethane sheath layer. The saline-alkaline tolerance communication cable has the advantages of simple structure, convenient production, low cost, high tensile strength and good anti-corrosion effect; the internal polyester film layer can effectively inhibit infiltration of saline moisture to direction of the conductor, the external polyurethane sheath further increases the external saline-alkaline tolerance performance, a plurality of steel wire cord threads are embedded in the polyester film layer, the tensile strength performance of the coaxial cable can be greatly increased, and the high strength corrosion resisting coaxial cable is suitable for using in zones with high saline-alkaline degree such as seaside and bad natural conditions.
Description
Technical field
The present invention relates to the cable technology field and establish, particularly a kind of high-strength corrosion-resisting coaxial cable.
Background technology
Along with China's rapid development of economy, cable all plays important role as the main media of modern communication in all trades and professions, use coaxial cable in a large number in the communications industry at present, but the intensity of present coaxial cable and barrier propterty are obviously not enough; Such as the cable of coaxial cable as the transmission communication signal, in sweltering heat and humid area, in case by moisture, moisture and saline and alkaline erosion, oxide etch will take place in conductor, thereby causes signal transmission errors, influences the normal operation of communications service; The tensile strength of its two present coaxial cables is not enough, when use in the area of constructing and natural conditions are abominable, is damaged easily.
The utility model content
At the defective of prior art, the purpose of this utility model is to provide a kind of high-strength corrosion-resisting coaxial cable, to solve existing communication cable easily by saline alkali corrosion and the not enough defective of tensile strength.
The utility model is to be achieved through the following technical solutions: comprise inner wire, insulating barrier, outer conductor and restrictive coating that from-inner-to-outer arranges, described insulating barrier comprises inner insulating layer and external insulation layer, be provided with laminated polyester film between the two, many all-steel cords of setting-in in the laminated polyester film; Described restrictive coating is the urethane jacket layer.
Described inner insulating layer is the teflon insulation layer, and external insulation layer is ethylene propylene rubber insulated layer.
Described inner wire is silver-coated copper wire, and described outer conductor is zinc-plated seamless copper tube.
The utility model is simple in structure, easy to make, with low cost, tensile strength is high and anticorrosion ability is good; Laminated polyester film by inside can effectively suppress saline and alkaline moisture to the infiltration of conductor direction, and the polyurethane jacket of outside has further improved the performance of the outside anti-saline alkali corrosion of coaxial cable simultaneously; Embedded by many all-steel cords at laminated polyester film in addition, increased the tensile property of coaxial cable greatly, be very suitable for saline and alkaline height and the abominable area uses of natural conditions such as seashore.
Description of drawings
Figure l is generalized section of the present utility model;
Among the figure: 1, urethane jacket layer, 2, zinc-plated seamless copper tube, 3, ethylene propylene rubber insulated layer, 4, laminated polyester film, 5, the teflon insulation layer, 6, silver-coated copper wire, 7, all-steel cord.
Embodiment
With reference to figure 1, a kind of high-strength corrosion-resisting coaxial cable comprises inner wire, insulating barrier, outer conductor and restrictive coating that from-inner-to-outer arranges, and insulating barrier comprises inner insulating layer and external insulation layer, be provided with laminated polyester film 4 between the two, many all-steel cords of setting-in 7 in the laminated polyester film 4; Restrictive coating is urethane jacket layer 1; Inner insulating layer is teflon insulation layer 5, and external insulation layer is ethylene propylene rubber insulated layer 3; Inner wire is silver-coated copper wire 6, and outer conductor is zinc-plated seamless copper tube 2.
The utility model is simple in structure, easy to make, with low cost, tensile strength is high and anticorrosion ability is good; Laminated polyester film by inside can effectively suppress saline and alkaline moisture to the infiltration of conductor direction, and the polyurethane jacket of outside has further improved the performance of the outside anti-saline alkali corrosion of coaxial cable simultaneously; Embedded by many all-steel cords at laminated polyester film in addition, increased the tensile property of coaxial cable greatly, be very suitable for saline and alkaline height and the abominable area uses of natural conditions such as seashore.
