A kind of electric wire and cable conductor
Technical field
The present invention relates to the electric wire that a kind of electric wire and cable conductor is suitable for various voltage class.
Background technology
Existing wires and cables industry is in order to improve current-carrying capacity, cost declining, it is proposed that high-strength copper-coated aluminum cable conductor, expansion Footpath steel-cored aluminium strand, hollow core cable, high voltage hollow cable, combined conductor power cable, multiple fission copper or aluminium busbar.But also It is not find a more effective fruit cost declining, improve the method for current-carrying capacity.It is copper, aluminium, copper that the conductor of above-mentioned series products, which uses, There is the conductor being dielectrically separated between alclad, copper aluminium, its shortcoming:
1. copper current-carrying capacity is small, temperature rise is of high cost.
2. aluminium current-carrying capacity is small, temperature rise, aluminium conductivity is with copper than relatively poor and oxidizable.
It is that metallurgical binding (match somebody with somebody by prior art copper and aluminium 3. copper clad aluminum current-carrying capacity is small, temperature rise, copper clad aluminum complex process It must be metallurgical binding to close use, not so there is electrochemical reaction), the adhesiveness of copper aluminium is that copper is not stratified with aluminium, is an entirety, Electric current distribution is uneven.For isometrical copper wire compared with copper-clad aluminum conductor, copper wire is bigger than copper-clad aluminum conductor current-carrying capacity, isometrical copper-clad Aluminium cable is not energy saving compared with copper cable, and waste and old CCA electric wire, in recycling, copper aluminum separation technique is complicated, pollution Seriously.
4. the shortcomings that multiple fission copper or aluminium busbar:Current-carrying capacity is small, temperature rise, is dielectrically separated between copper aluminium, copper aluminium electrification 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.
