【Summary description】 The State Grid Corporation has included high-speed aluminum alloy cable in the 2014 edition of the new technology list.

The State Grid Corporation has included high-speed aluminum alloy cable in the 2014 edition of the new technology list. This itself is the cable user department attaches great importance to aluminum alloy cable, and provides a technical basis for the development and application of medium and low voltage aluminum alloy cable for cable manufacturing enterprises and cable user departments. This will certainly have a positive effect on Chinese medium and low voltage cable market. From historical experience, any new wire and cable products, if not recognized by the user department, it is difficult to promote. Although cable development companies think this is a good new product, but users do not dare to use or unwilling to use, and it is impossible to promote. In previous years, for example, mineral insulated cables were not used in large numbers until the building department issued an official installation map. While the cable industry considers good products, such as nylon sheathed wire and crosslinked polyethylene insulated low-voltage cloth wire, although there is a national standard, the construction department has not clearly indicated that they can be used, but can not be promoted.

For aluminum alloy cable, the user department has done a good job in promoting the application of technology. China Building Standard Design and Research Institute has issued the "Aluminum Alloy Cable Laying and Installation - National Building Standard Design Reference Drawing" (10CD106), in order to standardize the laying and installation process of aluminum alloy cable. In addition, aluminum alloy rod and aluminum alloy cable national standards have been promulgated, the State Grid Company from the user's point of view, aluminum alloy cable into the new technology directory to promote. It was fully explained that in our country, aluminum alloy cable research, manufacturing, sales and use of each link, had formed a firm industrial chain.

Some people pointed out that aluminum alloy cable into the State grid new technology catalog temporary limited impact. This is a good point, but it lacks long-term strategic vision and is too eager to achieve quick results. Over the past 30 years, our cable industry has developed so many new products, none of which is "immediately produced and sold" after being developed by their own brains, all of which require certain technology and market preparation time. Even if the market needs a product, it must be certified and approved by users. What is said in "Southern Cable Review: Aluminum alloy cable is listed in the State Grid new technology directory to usher in the market spring with aluminum instead of copper" is put forward from the perspective of development. At the same time, some factors that are not conducive to the promotion of aluminum alloy cable are briefly described.

As for the aluminum alloy manufacturing industry, it is reported that the Chinese Society of Rare Earth pointed out that "the annual production of rare earth aluminum alloy in China is about 380,000 tons. From high-grade aluminum alloy used in missiles to ordinary daily aluminum products, from aluminum cable/aluminum pipe weighing up to a ton to aluminum foil, rare earth aluminum alloys are widely used. The annual production of rare earth aluminum alloy is expected to reach 500,000 tons by 2020. This is the same concept as the high-speed aluminum alloy used in modern aluminum alloy cables. Modern rare-earth aluminum cables use AA8000 series of high iron aluminum alloys. The US and Canada use the AA8000 series of high iron aluminium alloys for electrical aluminium, which are not restricted by rare earths. Therefore, we do cable product market forecast, to aim at the direction of development, do not do those meaningless look around, to have their own backbone.

No far-off plan has near worries. State Grid Corporation has not bid for aluminum alloy cable today, does not mean that tomorrow, the day after tomorrow will never bid, there should be a short preparation process. The technical policy of "replacing copper with aluminum" has strong vitality and guiding significance. We do not want to see in the "temporary" or "long-term" issue, spend too much energy on the discussion, but should be by the cable manufacturers to ponder, judge, and take appropriate action. However, it must be pointed out that if cable manufacturers do not seize the opportunity to prepare for all aspects of technology, it is bound to lose the opportunity of aluminum alloy cable market.
