Is aluminum alloy cable a substitute for copper cable? To understand this problem, it is necessary to understand the performance differences between aluminum alloy cables and copper cables, price differences, the proportion of aluminum alloy cables and copper cables used in Europe and the United States, the status quo of China's copper and aluminum production capacity, and the technical status of China's aluminum alloy cables. Now, Qingdao Tiango cable manufacturers will discuss with you whether aluminum alloy cables are alternatives to copper cables.

Aluminum alloy power cable is aluminum as the main conductor material, adding copper, iron, magnesium, silicon, zinc, boron and other alloying elements, through a special process to produce aluminum alloy as a conductor power cable.

Conductor performance improvement: Aluminum alloy power cable due to the addition of alloying elements in pure aluminum, so that the mechanical properties of aluminum alloy conductors have been greatly improved, enhanced bending, creep resistance and corrosion resistance.

Light weight: the conductivity of aluminum alloy is 61.5% of copper, and the carrying capacity is 79% of copper, the following comparison table can be seen that the weight of aluminum alloy cable with almost equal carrying capacity is only 65% of the copper core cable, and the comprehensive labor cost of transportation and engineering laying is also greatly reduced.

Low price: aluminum alloy cable carrying capacity is about 79% of copper, with aluminum alloy cable to replace the same carrying capacity of copper cable, generally increase the cross-sectional area of the copper cable 1.5 times choose aluminum alloy cable. Take the aluminum alloy cable of YJLHV-3×185+2×95 as an example to replace the copper cable of YJV-3×120+2×70.

Compared with copper core cables, aluminum alloy cables have unparalleled advantages over copper cables in terms of weight, price and installation. In other words, under the premise of the same electrical performance and better mechanical properties, the economic effect of aluminum alloy cable is obvious, and the application field is wide.

Development status of aluminum alloy cable technology in China

Foreign countries have more than 40 years of aluminum alloy cable use history, since 2006 aluminum alloy cable into China, after nearly 20 years of development, China's aluminum alloy cable from a technical point of view, or production point of view, and even construction, the technical level has been relatively mature, Tianxingcable aluminum alloy cable production also has many years of experience.

Although aluminum alloy cable has many advantages, some problems can not be ignored.

The terminal of the aluminum alloy cable may not keep up with the needs of the cable, because the particularity of the material of the aluminum alloy cable, resulting in the material selection, size, and the matching degree of the interface at the other end of the cable, there may be some trouble in the laying construction process.

The fire resistance is low, the fire resistance of the cable mainly depends on the conductor material, the cable conductor has three kinds of copper, aluminum and aluminum alloy, the melting point of copper is 1083℃, the melting point of aluminum is 660℃, in general, the alloy material is lower than the melting point of pure metal, that is to say, the melting point of aluminum alloy is lower than pure aluminum, in the fire resistance Angle, relative to pure copper or pure aluminum quality, Aluminum alloy has low fire resistance.


After the above introduction, Tianxing cable that aluminum alloy cable is the choice of replacing copper conductor cable, although there are still some problems that can not be ignored, but throughout the history of cable development in China, it can be seen that China's cable development history is the growth history of China's cable industry, this history has been moving in a good direction, copper core cable has completed the mature period, The maturity period of aluminum alloy cable is also coming.

Qingdao Tianxing Cable Co., Ltd. focuses on the production of customized wire and cable manufacturers, main: fire wire and cable, power cable, control cable and other products, exported to more than 40 countries and regions around the world, the annual production capacity of 1 billion yuan. 6000 square meters of storage, standing hundreds of millions of inventory, order demand for rapid distribution and delivery, large prices more favorable.
