Description
The present invention divides an application, and the original bill application number is " 200810036628.1 ", and the applying date is " on 04 25th, 2008 ", and denomination of invention is " novel alloy conductor, its preparation technology and relevant cables ".
Technical field
The present invention relates to the conductor material technical field, be particularly related to the alloy conductor material technical field, more specifically, refer to its preparation technology of a kind of novel alloy conductor and relevant cables, the performance of this novel alloy conductor surpasses general aluminium widely, can replace copper, be widely used among the cable of various models, various uses, all size.
Background technology
Along with the Chinese national economy sustainable development, cable work had been the second largest industry that is only second to automobile industry in the machinery industry already, and also being only second in the world the U.S. becomes world's second largest electric wire producing country.China's cable copper consumption generally accounts for the 65%-70% of the total copper consumption in the whole nation.Successively rise with copper, aluminium amount in recent years.Used copper amount is 3,500,000 tons in 06 year cable product, is 1,100,000 tons with the aluminium amount.Be divided into two at 1,100,000 tons of aluminium ingots.One is 900,000 tons and is used in the aerial condutor of doing steel reinforced aluminium conductor and so on, and one is 200,000 tons and is used in and does cable core.And before 06 year, the cable core of China is with 100,000 tons of aluminium quantity not sufficients, because 06 year copper valency is skyrocketing, cable core just rises to nearly 200,000 tons with the aluminium amount, only accounts for 5.7% of copper consumption then.This situation, the one, reflected that China's cable industry is backward in technique, the 2nd, it is not enough to cable product understanding to have reflected us, and the 3rd, to a kind of blindness demand of copper precious resources.
We know that copper is one of important strategic materials of country.China is the very weary country of plaque of copper ore resource, the used copper of China dependence on import all more than 70%.At the beginning of 21 century, copper, aluminium price generally differ between 2000-3000 yuan/ton, only differ in the time of minimum about 1000 yuan/tons, and copper is slightly higher.Since 04 year, the copper valency rose on the way, and particularly from 06 year Spring Festival, short some months rose violently 81900 yuan/tons from nearly 40000 yuan/tons of straight lines, has gone up nearly 2 times, and the trend that the aluminium valency rises is more steady, and the highest also only have about 24000 yuan/tons.Calculate from direct economic benefit, the proportion that also will add copper is 8.89g/cm
3, and the proportion of aluminium is 2.7g/cm
3,, a cable of same length increases by 3.3 times with copper than with aluminium again on weight, add the price multiple, and the height of the price of copper core cable is well imagined.Therefore how cable core is actively developed with new material and is replaced copper, and construction has important strategic importance and huge economic implications to the Chinese society doctrine.
Summary of the invention
Main purpose of the present invention is exactly the problems and shortcomings for above existence, a kind of novel alloy conductor is provided, and the charge is small for it, lightweight, lay conveniently, construction cost is low, and comparing to common aluminum steel has resistivity low, and conductance is good, tensile strength is high, the advantages such as elongation is large can replace copper, are widely used among the cable of various models, various uses, all size.
