Reaction solves, but copper, aluminium are two independent conductors, not equipotential, and the electromagnetic field between two conductors interferes with each other, mutually drop
Low current-carrying capacity.
The content of the invention
The shortcomings that the purpose of the present invention is overcoming the prior art, propose the bulk oxidation layer (oxidation for retaining copper and aluminium alloy
Very thin, the resistance very little of layer) isolated protective layer is used as, prevent electrochemical reaction, (such as almag, rare earth aluminium close copper with aluminium alloy
Gold) to coordinate be that overlap joint combines, by the division of isolated protective layer, copper, aluminium alloy formed two it is relatively independent but current potential is equal
Conductor, will not produce electromagnetic interference between each other, and electric current distribution even results greatly improve.
Realize the technical solution of the object of the invention:A kind of electric wire and cable conductor of the present invention is to be used for:Conductor is led using outer layer
Body is that copper, inner conductor are aluminium alloys, has copper sheathing as isolated protective layer, conductor structure by the use of the bulk oxidation layer of copper, aluminium alloy
Aluminium alloy bars (major diameter is rod, and diameter is line less than 5mm), copper twist aluminium alloy wire, expanding copper twists aluminium alloy stranded conductor, copper twists steel core
Aluminium alloy stranded conductor, expanding copper twist steel core aluminum alloy stranded wire;Above-mentioned conductor is needed according to voltage class can the additional insulation on conductor
Layer or shield dielectric layer.
The beneficial effects of the invention are as follows:A kind of electric wire and cable conductor is by the use of the bulk oxidation layer of copper and aluminium alloy as isolating
Protective layer, it is that overlap joint combines that copper coordinates with aluminium alloy, and electric current distribution even results are than copper, aluminium, copper clad aluminum (copper metallurgy of aluminium knot
Close), there is the conductor being dielectrically separated to get well between copper aluminium.1. isometrical copper wire is compared with copper sheathing aluminium alloy wire, copper sheathing aluminium alloy wire
Current-carrying capacity is big, and temperature rise is low;2. isometrical copper rod, compared with copper sheathing aluminium alloy bars, copper sheathing aluminium alloy bars current-carrying capacity is big, and temperature rise is low;③
Isometrical copper stranded conductor is compared with copper twists aluminium alloy wire, and copper strand aluminium alloy wire current-carrying capacity is big, and temperature rise is low.A kind of electric wire and cable conductor ratio
Have that the conductor current-carrying capacity being dielectrically separated from is big, and temperature rise is low between copper, aluminium, copper clad aluminum, copper aluminium.Metal oxide layer does isolated protective layer
Improve that current-carrying capacity, temperature rise be low, energy-saving effect of cost declining using realizing.
