Technical field
The invention belongs to the manufacture technology field of electric wire and cable material, and in particular to a kind of low-resistivity electric wire and its making
Technique.
Background technology
Wire, the wire especially containing aluminium and aluminium alloy, cupric and copper alloy has superior electric conductivity due to it, resistance to
Corrosivity, lightweight and good thermal conductivity, superior intensity and fatigue proof performance, obtain the common extensive of current social
Application.In power Transmission, power consumption is mainly on resistance.Meanwhile, in high voltage power transmission, aerial condutor is built on stilts electric power
The main building block of circuit, it is transmission electric current that it, which is acted on, conveys electrical power.Due to being erected above shaft tower, wire will be born
The imposed load such as deadweight and wind, snow, ice, while also suffering from the erosion of chemical substance contained by surrounding air.Therefore, do not require nothing more than
Wire has good electric property, enough mechanical strengths and resistance to corrosion, also requires light weight as far as possible and inexpensive.
Generally, in addition to outdoor transmission electric wire, wire in miscellaneous equipment using copper or copper alloy wire as
Main, this is primarily due in the wire of same diameter, and the conductance of copper or copper alloy is far above other metals.As electrical equipment is set
Standby increase, it is also increasing as the copper of wire or the consumption of copper alloy, and traditional copper alloy it is in use the drawbacks of also get over
Come more, maximum of which shortcoming is that resistivity is too high, causes most electricity to be lost in transmitting procedure, causes economy, the energy
Waste.
In summary, accordingly, it would be desirable to which a kind of electric wire of more preferable low-resistivity improves the deficiencies in the prior art, so as to push away
The development of dynamic electric wire industry.
