Aluminum alloy cable showcases the market opportunity of productsIssuing time:2022-09-09 16:59 According to the director, a recent internal meeting in the industry believes that the possibility of the introduction of the national standard for aluminum alloys is low before the first half of next year, and it will take time for the standard to be formulated. Secondly, in practical application, the scale of aluminum alloy replacement for copper may be limited. The person in charge of aluminum alloy cable companies generally said that aluminum alloy and copper have their own scope of application, which is not as rumored on the market "aluminum combination" The golden cable can be fully rolled out." Although the electrical performance of aluminum alloy cables has been improved compared with aluminum wires, there is still a gap with copper, and copper cables are still in places with high temperature, humidity, changeable surrounding environment, buried ground, and corrosion resistance irreplaceable; In terms of civil low-voltage cross-linked cables, buyers will also prefer to choose copper core cables. The real possibility of large-scale substitution effect is in the high voltage and ultra-high voltage of 10KV-35KV and above, but the state has strict control over cables above 35 thousand volts, so this piece of aluminum alloy cable needs to be further developed. Aluminum alloy cables first originated in the North American market, in the sixties and seventies of the last century, as the earliest inventor of aluminum alloy cables, the United States began to vigorously promote aluminum alloy cables in the North American market, as aluminum Alloys replace copper or pure aluminum as conductors for cable products. Aluminum alloy cables are mainly used in construction projects such as airports, military bases, office buildings, residences, hotels, supermarkets, colleges, stadiums, hospitals, factories, etc. United States Aluminum alloy cables have been successfully applied for nearly 50 years, and there have never been any safety accidents. Since aluminum alloy cables have entered the State Grid new technology catalogue, the market is highly concerned, and exhibitors at the China International Wire and Cable Exhibition have come up with their own aluminum alloy cable display products to gain market opportunities. However, after in-depth understanding with engineers from relevant enterprises, it was found that there are still bottlenecks in the promotion and application of domestic aluminum alloy cables. First of all, the national standard for aluminum alloy cables, which has attracted a lot of attention in the market, has been difficult to introduce, but some detailed standards are constantly being announced. For example: aluminum alloy conductors, alloy rod standards. "This is also a compromise to deal with the current situation of domestic aluminum alloy cables," said a director of the research institute involved in the formulation of the national standard for aluminum alloys There are more than 100 companies with aluminum alloy cables, but less than 10% of them can really produce products that meet foreign standards or higher domestic standards. Although the composition of aluminum alloy cables is public, foreign advanced production technology is right China is still in a state of blockade, and domestic enterprises mainly rely on their own research and development. Due to the lack of close cooperation between domestic enterprises and insufficient research and development efforts, there are many factory labels on the market, and these standards are uneven and increasing The difficulty of formulating aluminum alloy cable standards in line with national conditions. ” |
