Abstract
The present invention relates to the field of the power transmission and transformation device, and especially to a good conductive copper aluminum compound socket. The socket comprises an aluminium layer, an internal layer grapheme layer, a copper layer and an external layer grapheme layer from inside to outside. The conductive performance of the compound grapheme in the copper aluminum compound socket can be greatly improved, the usage amount of the copper can be effectively reduced, and at the same specification, the excellent conductivity can be ensured, and more requirements can be satisfied.
Description
Technical field
The present invention relates in power transmission and transforming equipment field, especially a kind of strong conductive copper aluminum composite bar.
Background technology
Copper-Aluminum compound row is commonly called as copper-clad aluminum conductor, and its meaning occurred is primarily to reduce the consumption of copper material.China belongs to
The country of lean copper richness aluminum, copper ore resource 70% relies on import, therefore vigorously advocates producer's research and development Novel copper-aluminium in National 863 plan
Composite, reduces China's consumption for copper material with this, reaches the strategic purpose of " saving copper with aluminum ".Additionally, due to copper material
Compare aluminium and want expensive many, so another remarkable effect of copper clad aluminum wire is exactly to reduce material cost for enterprise.Electrical resistance
The copper clad aluminum wire that energy is identical, about the 50% of its price only tradition fine copper row.On the premise of ensureing quality, it can be enterprise
Producing original benefit, the appearance of copper clad aluminum wire meets the Strategic Demand of country thus, meets the theory of social energy conservation consumption reduction,
Also comply with the demand of each Reducing Cost in Enterprises.
But owing to the electric conductivity of aluminum comes its electric conductivity under same size effect less than copper, conventional Copper-Aluminum compound
It is less than copper bar.
Summary of the invention
The present invention is directed to the problems referred to above and propose a kind of strong conductive copper aluminum composite bar, it is possible to effectively promote Copper-Aluminum compound row's
Electric conductivity.
To achieve these goals, the used technical scheme of the present invention is, a kind of strong conductive copper aluminum composite bar, from inside to outside
For aluminium lamination, internal layer graphene layer, layers of copper, outer layer graphene layer.
The described proportion shared by layers of copper is 5～20 %.
Described internal layer graphene layer and outer layer graphene layer thickness are 0.2～2 mm.
Graphene has perfect two dimensional crystal structure, and its lattice is the hexagon surrounded by six carbon atom, thickness
It it is an atomic layer.Between carbon atom bonded by σ, combination is sp2 hydridization, and it is the most excellent that these σ keys impart Graphene
Different mechanical property and structural rigidity.The iron and steel that the hardness ratio of Graphene is best is strong 100 times, diamond to be exceeded.At stone
In ink alkene, each carbon atom has the p electronics of a non-bonding, and these p electronics can move freely in crystal, and motion speed
The 1/300 of the degree up to light velocity, imparts the electric conductivity that Graphene is good, and under room temperature, its electron mobility is more than 15000cm2/V·
S, again ratio CNT or silicon wafer height, and resistivity about 10-6Ω cm, lower than copper or silver, minimum for world resistivity
Material.
In Copper-Aluminum compound is arranged, add Graphene can be greatly promoted its electric conductivity, can effectively reduce the use of copper
Amount, and under same size, it is ensured that superior electric conductivity, more demand can be met.
Accompanying drawing explanation
Fig. 1 is that Copper-Aluminum compound of the present invention arranges sectional view
1 is aluminium lamination, and 2 is layers of copper, and 3 is internal layer graphene layer, and 4 is outer layer graphene layer.
