Wonderful quotation: as a manufacturer, we should be responsible for the rational selection of aluminum alloy cable in the market. Some unrealistic propaganda, the promotion and application of security risk is not responsible for the users, but also irresponsible to the aluminum alloy cable industry. Considering the performance and safety of the aluminum alloy, it is not a problem that the pure aluminum cable is completely replaced.
Since the beginning of 1968, the southern wire and cable company has begun developing aluminum alloy power cables, and began to popularize this new cable conductor in many countries and regions in the Americas and Europe in the 70s of last century. Today, aluminum alloy power cable occupies an absolute dominant position in the field of municipal civil, industrial and commercial buildings in the United States.
Facts have proved that the use of aluminum alloy cables in the low-voltage power cable area on the demand side of the power system has no safety problems, and the cost saving effect is obvious. Through the actual use of decades of verification, Aluminum Alloy replace copper cable in power system provides power supply demand side, the best solution for residential, office buildings, industrial buildings and public facilities. In China, aluminum alloy cables have been developed from the initial low-voltage power cables to the current medium voltage cables, and even some enterprises have put forward the concept of "aluminum alloy can completely replace copper" in order to cater for marketing. This concept is not scientific.
In a scientific and prudent manner, we have the duty to guide the market to choose aluminum alloy cables reasonably. Some unrealistic propaganda, the promotion and application of security risk is not responsible for the users, but also irresponsible to the aluminum alloy cable industry. After all, aluminum alloy is aluminum alloy. In terms of performance and safety, it is not a problem to completely replace pure aluminum cable. However, some properties of aluminum alloy are only close to copper, not more than copper. Aluminum Alloy cable use field, it can not replace the copper in all areas.
Compared with foreign countries, aluminum alloys in China have certain particularities, not only in municipal and civil fields, but also in iron and steel, petrochemical, business entertainment and highway areas. Quite a few of them are aluminum alloy medium voltage cross-linked cables. Representative projects include Liaoning, Lingyuan, Ningxia iron and steel pagoda energy, Chengdu Happy Valley, Lu'an Jinling joy world. On these projects, it is often the use of millions, even thousands of yuan of aluminum alloy cables. After several years of use, the customer has given a high degree of evaluation to this new product, and the use of the cable is good. Aluminum alloy cable manufacturers provide the most economical and practical power supply solutions to customers on the premise of ensuring the quality and safety of the products.
Compared with pure aluminum cable, it has been a revolutionary breakthrough, which has solved the fatal defect of pure aluminum cable. In most common situations, such as residential, commercial buildings, municipal civil engineering can completely replace the use of copper. But in some important places and special places, such as urban power supply main line, large power plant, heavy polluting environment and difficult maintenance environment, aluminum alloy cable is not the best choice. These places highlight the safety and reliability of power supply, and the demand for power supply stability is very high. In this case, the problem does not exist originally in ordinary places Aluminum Alloy cable risk is highlighted, recommend the use of more security cable as a first choice.
The biggest advantage of aluminum alloy cable lies in the installation. The chain armored structure can provide better, more comprehensive protection for cable insulation, and can withstand not too much longitudinal tension. Aluminum Alloy cable can use the card along the wall surface in the interior, the cost of installation, which is impossible in any case of copper.
It is foreseeable that the aluminum alloy cable will be more and more high in the middle and low voltage distribution of civil buildings and factory buildings. In these areas the use of Aluminum Alloy copper cable compared advantages, its price is much higher than that of copper. However, in high pressure, high voltage, power lines, the main city of heavy pollution conditions, copper will not be replaced Aluminum Alloy cable. As a Aluminum Alloy cable manufacturer, to treat scientific Aluminum Alloy cable with copper, neither exaggerate the advantages of Aluminum Alloy, also do not cover up its shortcomings. Guide users, rational selection of aluminum alloy cable to provide users with a safe, reliable, cost-effective power supply solution.
