Abstract

The invention discloses an aluminum alloy cable. The aluminum alloy cable is made of the following raw materials by weight percentage: 1.3-1.8 percent of Co, 1.5-2 percent of Ni, 5-7 percent of Zn, 1-4 percent of Y, 0.5-0.9 percent of Zr, 0.5-2 percent of Nb, 1-3 percent of C, 0.5-0.9 percent of Si, 10-25 percent of Cr, 5-10 percent of V and balance of Al and accompanying impurities. The purpose of the invention is to overcome the existing technical defects, and the resistivity of the aluminum alloy is between the resistivity of aluminum and the resistivity of copper, is slightly higher than the resistivity of aluminum and lower than the resistivity of copper; when the section area of the alloy conductor is 1.5 times of the section area of copper, the electrical performance is the same, i.e., the effect of same current carrying capacity, resistance and voltage loss as that of copper is realized; since the aluminum alloy cable is made of a nonmagnetic material, even though three-phase unbalanced current exists, eddy current is not produced and the line loss can be reduced.

Description

A kind of aluminium alloy cable

Technical field

The present invention relates to cable material technical field, belong to a kind of aluminium alloy cable.

Background technology

For a long time, people to the selection of low-voltage cable for building, normally based on copper.Thinking copper conductor all higher than other conductors in electric property and the degree of reliability, is the only selection being used as cable material.But copper is as tellurian a kind of scarce resource, especially in our country, ore reserve are very limited, a large amount of dependence on import of Copper Ores.Under the overall situation advocating energy-conserving and environment-protective, sustainable development, whether we should break through inertial habits of application, under the condition be suitable for, go to accept more economically and the aluminium alloy cable of environmental protection? as everyone knows, the generation of any new things, new science and technology, the interests of existing industrial economy group will inevitably be touched, so that cause a large amount of blame, gone together and rival exclusion, suppress.But understand gradually along with increasing people and accept this fangle, in the past outmoded theory in the nature of things can eliminate by the mighty torrent of history.Just as now, numerous designers and owner are based on its dependable performance, economy, the considerations such as environmental protection, start one after another to select aluminium alloy power cable, exactly illustrating that aluminium alloy power cable is applicable to Chinese market, is the product meeting very much China's actual conditions, the demand of a lot of applications can be met simultaneously, have wide market and vitality.

Summary of the invention

The object of the invention is to overcome the deficiencies in the prior art, a kind of aluminium alloy cable is provided, be made up of the raw material of following weight portion: Co 1.6%, Ni 2%, Zn 6%, Y 1.5%, Zr 0.8%, Nb1.2%, C 2%, Si 0.8%, Cr 16%, V 8%, surplus is Al and adjoint impurity composition.

The present invention adopts following technical scheme to achieve these goals:

A kind of aluminium alloy cable, be made up of the raw material of following weight percents number meter: Co1.3 ~ 1.8%, Ni 1.5 ~ 2%, Zn 5 ~ 7%, Y 1 ~ 4%, Zr 0.5 ~ 0.9%, Nb 0.5 ~ 2%, C 1 ~ 3%, Si 0.5 ~ 0.9%, Cr 10 ~ 25%, V 5 ~ 10%, surplus is Al and adjoint impurity.

Preferably be made up of the raw material of following weight percents number meter: Co 1.6%, Ni 2%, Zn 6%, Y 1.5%, Zr 0.8%, Nb 1.2%, C 2%, Si 0.8%, Cr 16%, V 8%, surplus is Al and adjoint impurity.

Compared with the prior art, beneficial effect of the present invention is as follows:

1, resistivity is between aluminium and copper, a little more than aluminium, and lower than copper.By under identical ampacity, the aluminium alloy conductor weight of equal length is only the half of copper conductor, if be 100% calculating by the conductivity of copper, the conductivity of alloy conductor is about 61.2%, the proportion of alloy is 2.7, the proportion of copper is 8.9, then the resistance of (8.9/2.7) * (0.612/1)=2 i.e. resistance of 2KG copper and 1KG alloy is suitable, therefore, when the sectional area of alloy conductor is 1.5 times of copper, its electric property is identical, namely achieves the ampacity identical with copper, resistance and the loss of voltage;

2, aluminium alloy cable is nonmagnetic substance, even if there is the unbalanced electric current of three-phase also can not produce eddy current, can reduce the loss of circuit.

Embodiment

Below in conjunction with embodiment, the invention will be further described, but the present invention is not limited only to these examples, and under the prerequisite for departing from present inventive concept, any improvement of doing all drops within protection scope of the present invention.

Embodiment:

A kind of aluminium alloy cable, is made up of the raw material of following weight percents number meter: Co 1.6%, Ni 2%, Zn 6%, Y 1.5%, Zr 0.8%, Nb 1.2%, C 2%, Si 0.8%, Cr 16%, V 8%, surplus is Al and adjoint impurity.
