Abstract
The utility model discloses an aerial insulated cable, including the conductor, the conductor outside is by interior shielding layer, insulating layer and the weatherability protective layer that sets gradually outside to, the conductor includes compound core of fibre reinforced resins base and a plurality of the setting in the heat -resisting aluminium alloy single line in the compound core outside of fibre reinforced resins base. This cable has the characteristic that the quality is light, tensile strength is high, the electric property is good, heat stability is good, the creep properties is good, the weatherability is good.
Description
Technical field
The utility model belongs to field of cable technology, is specifically related to a kind of aerial insulated cable.
Background technology
Conventional overhead insulated cable adopts aluminium stranded conductor as conductor usually, and wear well polythene is as the simple structure of insulating material, because the metal activity of aluminium is comparatively strong, and creep properties is poor.Therefore, its shelf life and fail safe are all unsatisfactory.Common aerial insulated cable have drop in mountain area or physical features and the larger place of span is laid time, cable often because self overweight generation is seriously dangled, and cannot normally run.
The features such as at present both at home and abroad cable enterprise all forms and replaces conventional overhead insulated cable actively finding new material, and that what first aerial cable was considered is exactly is lightweight, good corrosion resistance, weatherability are good.
Summary of the invention
According to above the deficiencies in the prior art, technical problem to be solved in the utility model proposes a kind of aerial insulated cable, to reach the light object of cable weight.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of aerial insulated cable; comprise conductor; the screen set gradually from inside to outside outside conductor, insulating barrier and weather resistant protection layer, described conductor comprises fiber reinforced resin based composite core and some heat-resisting aluminium alloy single lines be arranged at outside fiber reinforced resin based composite core.
Preferably, described fiber reinforced resin based composite core and heat-resisting aluminium alloy single line are concentric stranding structure.
Preferably, described screen is Graphene compound height semiconductive semicrystalline polyolefin conductive material.
Preferably, described insulating barrier is 125 DEG C of cross-linking radiation polyolefin.
Preferably, the material of described weather resistant protection layer is weatherability crosslinked polyolefin materials.
The utility model beneficial effect is: 1, conductor adopts fiber reinforced resin based composite core to be that carrying core and Duo Gen heat-resisting aluminium alloy single line concentric stranding form, fiber reinforced resin based composite core intensity reaches as high as 2400MPa, it is the twice of general energy steel core intensity, and its density is only 1/4 of steel core, therefore quality is lighter.Use it to replace the steel core load-bearing of conventional overhead twisted wire, both alleviated cable body weight, and turn increased its mechanical performance.And heat-resisting aluminium alloy single line has the characteristic such as high creep resistance, high-tensile, high-elongation, deadweight bearing capacity is strong, Corrosion Protection is excellent, high-flexibility, switching performance safety and stability simultaneously.
2, semiconductive conductor screen material adopts Graphene compound height semiconductive semicrystalline polyolefin conductive material, Graphene is a kind of Novel Carbon Nanomaterials, compared with traditional semiconductive material, it has higher dielectric constant, better can reduce specific insulation, improves homogenizing electric field, realize conductor screen and the smooth gapless effect that insulate.
4, insulate employing 125 DEG C of irradiation crosslinked polyolefin insulating material, and IXPE is after electron beam to irradiate crosslinked, and mechanical performance improves greatly, guarantees that cable has excellent electric property, mechanical performance.The long-time running temperature of cable is at 125 DEG C, and compared with common cable, the mechanical and physical performance of cable is excellent, and ampacity improves greatly, and useful life rises appreciably.
5, outermost layer adopts weatherability crosslinked polyolefin materials to use as protective layer, and it has excellent weatherability, avoids insulating material and directly contacts with external environment condition, substantially increase the useful life of cable.
Accompanying drawing explanation
Below the content expressed by this Figure of description and the mark in figure are briefly described:
Fig. 1 is the structural representation of embodiment of the present utility model.
In figure 1, fiber reinforced resin based composite core, 2, heat-resisting aluminium alloy single line, 3, screen, 4, insulating barrier, 5, protective layer.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, embodiment of the present utility model is as the effect of the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part and operation principle, manufacturing process and operation using method etc., be described in further detail, have more complete, accurate and deep understanding to help those skilled in the art to inventive concept of the present utility model, technical scheme.
As shown in Figure 1; a kind of aerial insulated cable; comprise conductor; the screen 3 set gradually from inside to outside outside conductor, insulating barrier 4 and weather resistant protection layer 5, described conductor comprises fiber reinforced resin based composite core 1 and some heat-resisting aluminium alloy single lines 2 be arranged at outside fiber reinforced resin based composite core.
Conductor is formed by fiber reinforced resin based composite core 1 and Duo Gen heat-resisting aluminium alloy single line 2 concentric stranding; Graphene compound height semiconductive semicrystalline polyolefin conductive material forms conductor shield; 125 DEG C of irradiation crosslinked polyolefin insulating material form insulating barrier, and weatherability crosslinked polyolefin materials is as protective layer.
Corresponding vibrational power flow and Material selec-tion are respectively:
Conductor is that fiber reinforced resin based composite core 1 and Duo Gen heat-resisting aluminium alloy single line 2 concentric stranding are formed, conductor layer any surface finish, impulse-free robustness;
Screen 3 adopts Graphene compound height semiconductive semicrystalline polyolefin conductive material;
Insulating barrier 4 adopts 125 DEG C of irradiation crosslinked polyolefin insulating material, and surface should bright and clean, smooth, the defect such as bubble-free, crackle, impurity, mechanical damage;
Protective layer 5 adopts and extrudes weatherability crosslinked polyolefin materials, and surface should the defect such as bright and clean, smooth, bubble-free, crackle, impurity, mechanical damage.Cable lettering should correct, clear, scuff.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technical scheme is carried out; or design of the present utility model and technical scheme directly applied to other occasion, all within protection range of the present utility model without to improve.The protection range that protection range of the present utility model should limit with claims is as the criterion.
