Aluminum alloy cable will have greater effect in the low voltage distribution field

Since 1968, the Southern Cable Company of the United States began to develop and produce aluminum alloy cables. By the 1970s, the United States, Europe, and other countries and regions began to promote the use of this new type of cable conductor. Today, aluminum alloy cables occupy an absolutely dominant position in the fields of municipal, civil, industrial, and commercial construction in the United States.

At present, domestic aluminum alloy cables have been used for several years, users have consistently given high praise to this emerging product, and the cable has been used with good results. Under the premise of ensuring product quality and safe use, aluminum alloy cable manufacturers provide customers with the most economical and practical power supply solutions.

There is no problem in the field of low-voltage power distribution, high pressure is not yet mature

Facts have proved that the use of aluminum alloy cables in the field of low voltage power cables on the demand side of the power system does not present any problems in safety and that cost savings are significant. Through decades of actual use verification, aluminum alloy cables have replaced low-voltage power copper cables on the demand side of the power system, providing the best power supply solutions for residential buildings, office buildings, industrial plants and public facilities. At present, in order to cater for marketing, some domestic companies have begun to supply aluminum alloy conductors with power cables above 10KV to the market without fully grasping the technology and production process and application technology of aluminum alloy low-voltage power cables. Aluminum alloy conductors are used to make fabric wires (BV lines), and even some companies have proposed the concept that "aluminum alloys can completely replace copper" in order to cater to marketing. In fact, this concept is not scientific.

Aluminum alloy cable should follow safety science substitution rules

As a person who has been engaged in the manufacture and application of aluminum alloy cables and has a North American background and has brought in mature aluminum alloy cable technology and advanced production technology from North America to insist on being a fine-quality lead alloy industry, he said, “We want to With a scientific and prudent attitude, we have the responsibility and obligation to guide the market to scientifically and reasonably select aluminum alloy cables." Some unrealistic publicity and the promotion and application of security risks are both irresponsible to users and irresponsible to the aluminum alloy cable industry. Aluminum alloy power cables are generally considered to replace copper-core power cables in markets such as civil buildings, municipal engineering, and industrial and commercial buildings without problems due to performance and safety considerations. Aluminum alloy cable instead of copper core cable should respect the fact that the electrical properties of the two materials are different, and should be used in accordance with the replacement of the copper cable by about 1.5 times the section of the copper cable cross-section in order to meet the electrical properties after replacement. There can be no domestic flair for the design of electrical designers in design. If there is an original design plan, it should be calculated and verified according to the original design.

Aluminum alloy cable is not the best choice for special occasions

Mr. Wang, the chief marketing director of the leading brand Shang Shanxing Alloy Cables, pointed out that the alloy cable is a revolutionary breakthrough compared to the pure aluminum cable and solved the fatal flaw of the pure aluminum cable. In most common situations, such as residential, commercial buildings, municipal civil engineering and other fields can completely replace the copper cable to use. In some important places and special places such as fire fighting, mines, and urban power grids, aluminum alloy cables are not the best choice. In this case, it is better to use the national standard high-quality copper cables as the first choice.

The biggest advantage of aluminum alloy cable is the installation. The chain armor structure provides better and more complete protection for cable insulation and can withstand greater longitudinal pull than copper cables. The aluminum alloy cable can be used in the room with a line card to apply along the wall, saving the installation cost. This is what the copper cable can't do anyway. However, due to the special nature of the aluminum alloy cable, the connection technology is more demanding than the copper cable. At present, only a few leading brands such as Shang Shanxing alloy cable have mastered the technology.

Aluminum alloy cable connection terminal problem is a major problem in the industry to be overcome

At present, the difficulty of using aluminum alloy cables lies in the fact that domestically, apart from the use of Sunstar alloy cables, it has inherited the successful experiences and standard practices of the safe use of aluminum alloy cables in North America and other countries for the past 50 years, and is the first to successfully develop aluminum alloy copper connections that are consistent with its cable performance. Terminals, with the ability to provide aluminum alloy cable full set of technical products, the other brands in the industry do not have the ability to match the aluminum alloy copper connection terminal products with the performance of aluminum alloy cables, these brands are usually helpless, but also the original use of the wrong Copper-aluminum transition terminals for aluminum cables and so-called alloyed alloy transition terminals introduced by some domestic manufacturers recently. (The chemical composition, electrical properties, mechanical properties, and compressive creep properties of alloy terminals of such alloy transition terminals are desirable. The performance of the aluminum alloy cable connected does not match) As the aluminum alloy cable connection terminal, this is a wrong practice and recognition, because the presence of aluminum in the terminal (or alloy with the aluminum alloy cable does not match the performance), all aluminum cable Deficiencies and safety hazards still exist, making the advantages and value of using aluminum alloy cables Can be truly played and embodied, which is different from the direct use of aluminum cable? Aluminum alloy cable in the application without matching aluminum alloy copper cable connector can be connected with the performance of the aluminum alloy copper joint problem is the aluminum alloy industry to be solved of. This directly reflects the correct application of aluminum alloy cables.

Aluminum alloy cable will have greater effect in the low voltage distribution field

It can be foreseen that aluminum alloy cables will account for an increasing proportion of low-voltage distribution in civil buildings and factory buildings. The use of aluminum alloy cables in these areas has significant advantages over copper cables, and their cost performance is much higher than that of copper cables. However, in the field of high-voltage, ultra-high-voltage and cloth-wires above 10KV, copper cables will not be replaced by aluminum alloy cables. As an aluminum alloy cable manufacturer, it is necessary to treat aluminum alloy cables and copper cables scientifically, which neither exaggerates the advantages of aluminum alloy cables nor hides the deficiencies of their application fields, and guides users to scientifically and reasonably select aluminum alloy cables to provide users with safety The reliable, cost-effective power supply solution.

Recently, a cable industry professional once said in an interview with reporters: “At present, the use of aluminum alloy conductor cables has become a major trend in the world. In this respect, it has been practiced in many countries, and our country should also try.” The concept of aluminum alloy cable has been gradually accepted by the domestic market, and the market usage has grown rapidly. The application of aluminum alloy cable in China will continue to increase, and there will be greater efforts in the field of low voltage distribution.

National policy level strongly supports the development of aluminum alloy cables

At home, because of history, technology and other reasons, copper-core cable has become the most well-known, it almost occupies the entire cable market, can be described as "distinguished." Copper core cable has the characteristics of high strength and large current-carrying capacity, which is unquestionable. The problem is that China’s copper resources are intrinsically scarce. In recent years, the contradiction between supply and demand in the market has become prominent, leading to the soaring price of copper, plus copper. Cable installation is difficult to install, high installation costs, easy to steal, easy to aging and other shortcomings, the industry's voice for the replacement of copper cables with alloy cables is growing louder and louder. To this end, the national level has also begun to make strategic arrangements for the development of aluminum alloy cable technology. Aluminum alloy cables have been explicitly included in the National Industrial Adjustment Catalog. Recently, the State Grid Corporation of China officially responded to the 12th session of the National People's Congress No. 9887, "Proposal on Expanding the Application of Aluminum Alloy Cables in the Electric Power Industry," and the State Grid Corporation stated clearly in the "Reply" that the wire and cable "is based on aluminum. "Copper" has important strategic significance. To further promote the application of aluminum alloy cables in power systems, it has been incorporated into the 2014 version of the State Grid Corporation's new technology catalog. As the electrical properties and excellent mechanical properties of aluminum conductors are gradually recognized by users, the price is about 20% lower than copper cables. Therefore, in the laying of power cables, the proportion of aluminum alloy cable usage has increased significantly. It will usher in a huge opportunity for development. As a country with a shortage of copper resources, actively developing and producing qualified aluminum alloy cables and supporting fittings with the same performance as the cables serve the power transmission and distribution industry. Not only does it have a huge market space, but also the cable industry is building “resource-saving and environment-friendly”. "Friendly" society's due responsibilities and obligations.

The development of aluminum alloy cables and aluminum alloy connection terminals is an urgent practical issue.

Some experts predict that in the next five years, China's aluminum alloy cable market will form a market size of over 300 billion yuan. This is considered to be a "gold mine" to be developed in China's cable market. The domestically developed favorable policies have also provided guarantees for the promotion of aluminum alloy cables. Because many companies do not pay attention to their own conditions, have launched aluminum alloy cable projects, most companies do not even connect the conductor aluminum alloy technology, application of aluminum alloy cable manufacturers to provide supporting aluminum alloy connection terminals and other issues To understand this, blindly investing in equipment, thinking that there is equipment that can produce alloy cables, is still used to thinking about copper cables. As the situation continues to develop, the aluminum alloy cable market will not take years and even within 1-2 years, counterfeit products will be flooded. Because the unqualified aluminum alloy cable is not mastered due to its alloy technology and the production equipment is not professional, the electrical performance of this aluminum alloy cable is not as good as that of the aluminum cable, and the mechanical performance may not be improved. In fact, it is not as good as the aluminum cable. The unsolved problem of aluminum alloy connection terminals will make it difficult for the application of aluminum alloy cables to remain hidden. If such products flood the market with blind applications, there is no doubt that the market will lose confidence in the alloy cables.

At present, there are only a handful of domestic production companies that have the ability to produce aluminum alloy cable products. It is known that only those companies that truly possess the mature technology and production capacity of American alloy cables are only a few leading companies such as Shang Shanxing alloy cables. At the same time with the ability to support mature aluminum alloy connection terminals, it is understood that only lead the brand on the good star alloy cable. Therefore, Chinese aluminum alloy cable manufacturers have a correct understanding of the value and application conditions of aluminum alloy cables. How to invest more human and material resources in the research and development of aluminum alloy cables and aluminum alloy connection terminals is an urgent practical issue. The future will win the reality of the vast market.
