With the continuous development and progress of the economy, society and electrification era, the role of cables in people’s production and life continues to increase. At present, in any large public building, electrical investment basically accounts for about 10% of the total project investment, and the proportion of cables in the entire electrical investment budget is basically more than 50%. Traditional cables are made of copper. Core-based. In recent years, with the continuous acceleration of my country’s modernization, various public infrastructures, commercial buildings, and high-rise residential buildings have been launched in large numbers. Over 70% of these buildings use copper-core cables. my country is a copper-deficient country. The stock of copper ore resources is about 36 million tons. The import dependence of refined copper ore is much higher than that of iron ore and oil by more than 70%. The large-scale use of copper core cables and wires has led to a rise in copper prices, while copper prices have risen sharply It will cause the increase of social costs and even the repeated theft of cables. These problems make us urgently need to find a product that can replace copper core wires and cables

Aluminum alloy cableshave been widely used in overseas markets

Copper is an important international commodity. The high price of copper will not only affect China, but will have a greater impact on some European and American countries. Therefore, they have already begun research on “substituting aluminum for copper”. At present, in the United States, Canada and other developed countries, a kind of aluminum alloy as the conductor, cross-linked polyethylene insulation, interlocking aluminum alloy tape armored low voltage cable is widely used. This metal armored cable has been installed and operated in the North American market for nearly 40%. year.
Aluminum alloy cable not only completely replaces traditional copper core cable in terms of electrical performance and safety performance, but more importantly, it is lower than 50% of the cost of traditional copper core cable under the premise of meeting the same electrical performance, which saves engineering investors. A large amount of power facility investment costs, and in practical applications, aluminum alloy cables have half the weight of copper core cables under the equivalent premise, and have good flexibility (the bending radius is half smaller than copper cables, and copper cables are 15–20 times The outer diameter of the AAAC Conductor is only 7–8 times the outer diameter), the installation is more labor-saving and labor-saving, the installation period is advanced, and the installation cost is also greatly reduced. Because of its reliable connection, light weight, small bending radius, convenient installation, good heat dissipation, bridge saving, resource saving, low smoke and halogen free, it is widely used in airports, military bases, offices, residences, hotels, supermarkets, colleges, sports Venues, hospitals, industrial plants, data processing centers, prisons and other places.
The quality of China’s aluminum alloy cables has reached the international leading level

In the past few years, China’s aluminum alloy cable businesshas made remarkable progress, and aluminum alloy cable technology and products have gradually been accepted by domestic users. Nowadays, aluminum alloy cable technology is playing an increasingly important role in the implementation of the country’s vigorously promoted “replacement of copper with aluminum” in the practice of building a resource-saving society in the field of medium and low voltage power distribution. The aluminum alloy cable industry and market are also about to enter Flourishing stage.
