Abstract
The utility model discloses a copper stranded wire. The copper stranded wire comprises a plurality of copper wires, The center of the copper wires is provided with a metal wire, the copper wires are divided into internal layer copper wires and external layer copper wires, the internal layer copper wires are stranded in the shape of a spiral, the internal layer copper wires are wound and completely wrapped on the surface of the metal wire, the amount of the external layer copper wires is three, and the external layer copper wires are wound on the surfaces of the internal layer copper wires. According to the utility model, by the cooperation of the metal wire and the copper wires, not only is the copper stranded wire provided with a good transmission performance, but also the intensity of the copper stranded wire is enhanced, and the copper stranded wire is provided with a good mechanical property.
Description
Technical field
The utility model relates to field of cables, relates in particular to a kind of copper stranded conductor.
Background technology
The copper stranded conductor that the electric equipments such as the transformer of prior art are used is all to adopt structure to meet the copper stranded conductor of GB GB3953, and this GB GB3953 copper stranded conductor that meets is by many stranded formation of strand, and each root strand is by many stranded formation of copper cash.But due to each root strand by many stranded formation of copper cash, this is less and stranded technique causes the pitch diameter of strand, therefore the strand of this copper stranded conductor is relatively hard, the copper wire diameter of the strand of this copper stranded conductor is larger in addition, make whole copper stranded conductor relatively hard, affect the assembly performance of the electric equipments such as transformer.And current copper stranded conductor is all only by zinc-plated or silver-coated copper wire stranded forming simply, mechanical performance is poor, in use is very easy to fracture.
The utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide the copper stranded conductor that a kind of intensity is high, be not easy to fracture.
For achieving the above object, the utility model provides following technical scheme: a kind of copper stranded conductor, comprise many copper cash, described copper cash center also is provided with wire, described copper cash is divided into internal layer copper cash and outer copper cash, described internal layer copper cash is stranded in the shape of a spiral, and the internal layer copper cash is wound around and complete covering metal silk surface; The quantity of described outer copper cash is 3 and is wrapped in the internal layer copper line surface.
By adopting technique scheme, copper cash is divided into internal layer copper cash and outer copper cash, the internal layer copper cash is stranded in the shape of a spiral to be arranged in outer copper cash, wire is placed in the internal layer copper cash, the three forms copper stranded conductor together, under copper cash and acting in conjunction wiry, has strengthened the transmission performance of copper stranded conductor, also strengthen the mechanical performance of copper stranded conductor, made copper stranded conductor be difficult for being fractureed.
The utility model further is set to: described material wiry is titanium alloy.
By adopting technique scheme, titanium is a kind of important structural metal, and intensity is high, corrosion resistance good because having, the thermal endurance high is widely used in every field for titanium alloy.The wire that adopts titanium alloy to make also has the performances such as intensity is high, corrosion resistance good, thermal endurance is high, has greatly strengthened the mechanical strength of copper stranded conductor.
The utility model further is set to: described internal layer copper cash and outer copper line surface are equipped with tin coating.
By adopting technique scheme, tin coating has good antioxygenic property, and the protection copper cash is not by the outside air oxidation, even, in the situation that dark moist environment or bad weather also can be protected copper cash, play antirust, anti-oxidation effect; In addition, tin coating has also strengthened the aesthetic property of copper stranded conductor.
The utlity model has following advantage: by wire and coordinating of copper cash not only having good transmission performance, and strengthened the intensity of copper stranded conductor, had good mechanical performance.
The accompanying drawing explanation
Fig. 1 is the cutaway view of the utility model copper stranded conductor;
Fig. 2 is the left view of copper stranded conductor shown in Figure 1.
In figure: 1, internal layer copper cash; 2, wire; 3, tin coating; 4, outer copper cash.
Embodiment
Referring to figs. 1 through shown in Figure 2, the copper stranded conductor of the present embodiment, comprise many copper cash, described copper cash center also is provided with wire 2, described copper cash is divided into internal layer copper cash 1 and outer copper cash 4, and described internal layer copper cash 1 is stranded in the shape of a spiral, and internal layer copper cash 1 is wound around and complete covering metal silk 2 surfaces; The quantity of described outer copper cash 4 is 3 and is wrapped in internal layer copper cash 1 surface.
By adopting technique scheme, copper cash is divided into internal layer copper cash 1 and outer copper cash 4, internal layer copper cash 1 is stranded in the shape of a spiral to be arranged in outer copper cash 4, wire 2 is placed in internal layer copper cash 1, the three forms copper stranded conductor together, under the acting in conjunction of copper cash and wire 2, has strengthened the transmission performance of copper stranded conductor, also strengthen the mechanical performance of copper stranded conductor, made copper stranded conductor be difficult for being fractureed.
The material of described wire 2 is titanium alloy.
By adopting technique scheme, titanium is a kind of important structural metal, and intensity is high, corrosion resistance good because having, the thermal endurance high is widely used in every field for titanium alloy.The wire 2 that adopts titanium alloy to make also has the performances such as intensity is high, corrosion resistance good, thermal endurance is high, has greatly strengthened the mechanical strength of copper stranded conductor, and in the present embodiment, the material of wire 2 is preferably titanium alloy.
Described internal layer copper cash 1 and outer copper cash 4 surfaces are equipped with tin coating 3.
By adopting technique scheme, tin coating 3 has good antioxygenic property, and the protection copper cash is not by the outside air oxidation, even, in the situation that dark moist environment or bad weather also can be protected copper cash, play antirust, anti-oxidation effect; In addition, tin coating 3 has also strengthened the aesthetic property of copper stranded conductor.
The utlity model has following advantage: by wire 2 and coordinating of copper cash not only having good transmission performance, and strengthened the intensity of copper stranded conductor, had good mechanical performance.
The above is only preferred implementation of the present utility model, and protection range of the present utility model also not only is confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, in the some improvements and modifications that do not break away under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
