Abstract
The utility model discloses a carbon fiber composite strengthening core energy-saving conductor. The carbon fiber composite strengthening core energy-saving conductor comprises an outer twisted aluminum layer which is formed by twisting first aluminum wires, an inner twisted aluminum layer which is formed by twisting second aluminum wires and a carbon fiber composite core wire. The inner twisted aluminum layer is positioned between the carbon fiber composite core wire and the outer twisted aluminum layer. The cross sections of the first aluminum wires and the second aluminum wires are ladder-shaped, and the twisting directions of the outer twisted aluminum layer and the inner twisted aluminum layer are opposite. A glass fiber layer is further arranged between the inner twisted aluminum layer and the carbon fiber composite core wire. The carbon fiber composite strengthening core energy-saving conductor disclosed by the utility model has the advantages of high tensile strength, light weight, good durability and difficult aging, can be used in harsh environments, has the effect of energy saving, can effectively replace the existing steel core aluminum twisted wire, and can well adapt to the development demand of the electric power industry, thus national resources are effectively saved.
Description
Technical field
The utility model relates to a kind of link of carbon fiber composite core wire, the special-purpose splicing fitting of especially a kind of carbon fiber composite core wire.
Background technology
Along with the development of China's economic construction, electricity needs constantly increases, and cable is increasing as the critical piece demand of delivery of electrical energy, and China is used for construction and the transformation of thousands of kilometers transmission line every year with 1,000,000 tons wire.Mostly the cable conductor of present domestic usefulness is steel reinforced aluminium conductor and aluminium alloy conductors steel, the weight of these wires is larger, resistance is larger, from and cause the transmission of electricity expense high, and operating temperature is lower, can not adapt to the operation under hot conditions, so electric power transfer becomes " bottleneck " of electric power industry development, the overhead cable wire is being studied to replace traditional steel reinforced aluminium conductor by various countries.
Thus, people have invented the tensile strength height, quality is light, the carbon fiber composite core wire of good endurance, but studies show that because the carbon fiber composite core wire structure has particularity, existing splicing fitting should not use, it is relatively poor to connect effect, in use exist the unstable problem of connection, also inconvenience is installed simultaneously, therefore be necessary to invent a kind of special-purpose gold utensil that connects better effects if.
Summary of the invention
The purpose of this utility model is design for the deficiency that solves above-mentioned technology a kind of easy for installation, connect better effects if the special-purpose splicing fitting of carbon fiber composite core wire.
The special-purpose splicing fitting of carbon fiber composite core wire that the utility model is designed, comprise outer tube and hookup, described hookup is positioned at the outer tube middle part, the both sides of hookup are provided with two wedge shape holders in the described outer tube, described wedge shape holder is provided with back-up ring away from a side of hookup, is provided with the wedge grip that clamps for carbon fiber complex core in the described wedge shape holder; The taper end of described wedge grip is exposed described wedge shape holder, and described hookup is connected with the wedge shape holder by bolt; The outside at described back-up ring is provided with internal lining pipe.Preferably the two ends of described hookup are provided with the screw thread of opposite direction.
The special-purpose splicing fitting of the carbon fiber composite core wire of the utility model gained, during connection, the carbon fiber core of two ends docking puts respectively the wedge shape holder, insert the wedge shape holder after again wedge grip being clamped carbon fiber core, then by bolt wedge shape holder and hookup are tightened docking, put at the internal lining pipe, the outer tube that penetrate in advance wire at last and carry out crimping, will carry out to the two ends symmetry from the central point of splicing fitting all the time during crimping.The special-purpose splicing fitting of this carbon fiber composite core wire, adopt the fit structure of wedge shape holder and wedge grip, can realize self-locking, the effect that in use has " drawing tighter and tighter ", therefore connect better effects if, connect more firm, thereby so that carbon fiber composite core wire can use in power industry better.
