Abstract
The utility model relates to a high and low temperature resistant fifth type cable for field operation. The utility model belongs to the technical field of an electric cable. The utility model comprises a cable core, an insulation and a protective sleeve, wherein, a plurality of strands of tinning copper wires are hinged to form the cable core. The periphery of the multi-strand hinged tinning copper wire is provided with the insulation 3 made of neoflon (abbreviated FEP) material, and the outermost layer is provided with the protective sleeve 1 made of silicon rubber material. The inner part of a protective sleeve layer is longitudinally and uniformly provided with high intensity aramid fiber reinforced polymer 2. The utility model has the advantages of reasonable and simple structure, easy production and fabrication, low cost, small volume, light weight and long service life. A conductor of the cable core adopts the multi-strand hinged tinning copper wire, which improves the transmission performance of the electric cable. The insulation structure adopts the neoflon (FEP) for insulation, which leads the electric cable to have good low smoke flame retardant properties. The protective sleeve made of silicone rubber has very high heat resistance, freezing resistance and aging resistance and has good insulating performance. The cable is formed in a star quad mode, transmission performance is stable, declining consumption is low, and performance of crosstalk interference is little. The high and low temperature resistant fifth type cable for field operation is suitable for being used for field mobility busywork.
Description
Technical field
The utility model relates to the structure of cable, and particularly the cable of high-low temperature resistant specification requirement belongs to cable
Technical field.
Background technology
Along with rapid development of social economy, worldwide " information superhighway " makes the mankind enter the information age, and broadband networks has become the new focus that network service already develops.The broadband has entered fast-developing track in the world, and the development of domestic broadband has also had very big starting.Along with the fast development of China's industry, the five class cables that many particular job field need be used are the high and low frequency superior performance not only, and the anti-collision performance that requires cable to have good high and low temperature resistance, excellence, can be adapted at mobile occasion and use.Five traditional class cables are made up of polyethylene (PE) insulation and polyvinyl chloride (PVC) sheath, but because polyethylene insulation and pvc sheath environmental resistance are poor, can only be applicable to place uses such as indoor.
The utility model content
The purpose of this utility model is exactly to lay to conform and require the shortcoming of difference to improve for overcoming existing five class cables, provides a kind of bigger serviceability temperature scope, transmission performance is stable, anti-collision performance is excellent high-low temperature resistant field work with five class cables.
The realization of the utility model purpose is by the improvement of existing five class cables is finished.High-low temperature resistant field work is with five class cables, comprise cable core, insulation and sheath, it is characterized in that cable core 4 is the strands tinned copper wire, strands tinned copper wire periphery is provided with perfluoroethylene-propylene (being called for short FEP) insulated with material 3, outermost layer is provided with the sheath 1 of silastic material, vertically evenly is laid with high strength aramid fiber 2 in the restrictive coating.Said strands tinned copper wire is a star quad stranding formula strands structure.
The utility model is rational in infrastructure, simple, manufactures easily, and cost is low, and volume is little, in light weight, the life-span is long.The cable core conductor adopts the strands tinned copper wire, can increase the softness of cable, reduces the decay of cable under the high-frequency digital signal transmission, improves the transmission performance of cable; Insulation system adopts perfluoroethylene-propylene (FEP) insulation, makes cable have good high-low temperature resistant and low-smoke and flame retardant performance; Silicone rubber jacket makes cable have very high thermal endurance and excellent cold resistance, and ageing-resistant and excellent insulation property can be used under-90～+ 250 ℃ situation for a long time; Adopt star quad stranding formula stranding, transmission performance is stable, and attenuation is low, and the cross-talk performance is little; Silicon rubber directly is extruded on the insulation stranding, makes cable have stronger elasticity and flexibility, and evenly places aramid fiber in silicone rubber jacket, strengthens the tensile strength of cable, is suitable for open-air mobility operation and uses.Excellent popularization using value and market prospects are arranged.
Description of drawings
Accompanying drawing is a structural representation of the present utility model, 1 sheath, 2 aramid fibers, 3 insulation, 4 cable cores among the figure.
Embodiment
With the tinned copper wire is cable core 4 conductors, adopt the star quad stranding formula to be twisted into cable core, perfluoroethylene-propylene (being called for short FEP) insulated with material 3 is set in the outside of multiply tinned copper wire, in the periphery of insulating barrier silastic material sheath 1 is set, high strength aramid fiber 2 vertically evenly is set in the silicone rubber jacket layer.
Claims (2)
1, a kind of high-low temperature resistant field work is with five class cables, comprise cable core, insulation and sheath, it is characterized in that cable core (4) is the strands tinned copper wire, strands tinned copper wire periphery is provided with perfluoroethylene-propylene, is called for short FEP insulated with material (3), outermost layer is provided with the sheath (1) of silastic material, vertically evenly is laid with high strength aramid fiber (2) in the restrictive coating.
