Cable is no stranger to the people speaking, in contemporary life, this is to a few or several groups of mutually insulated conductor wire for transmitting information through the use of a protective layer made of a now widely used in power systems, information transmission systems,s and instrumentation systems. We can even say a cable has been everywhere, did not play a huge role in the cable, normal human life will be a huge impact.
Time cable is very early in the Qing dynasty, Shanghai had already seen the first root of the power cable, with the rapid development of technology, more and more types of cables: power cables, control cables, computer cables, signal cables, mining cables, AAAC conductor and so on, of which AAAC conductor particularly rapid development in recent years, rapid increase market share.
AAAC conductor is aluminum alloy material as a conductor, through a special deal with the production from the new power cable. Class cable greatly improves the flexibility is poor, low elongation of original AAAC conductor and other shortcomings, enhance the continuity and reliability of the connection. In addition, the conductivity of the AAAC conductor is also higher than a lot of the materials of the cable, compared to copper cables, in addition, its lightweight, has low installation costs, has low wear, and the price is relatively cheap.
These features are also fully demonstrated the advantages of the AAAC conductor. Due to its good mechanical and electrical properties, AAAC conductors in a variety of buildings, factories, entertainment use, even in metallurgy, iron and steel, petroleum, aerospace, military, and other important sectors play a huge role.
Good creep resistance of AAAC conductor, alloy material with special treatment to promote aluminum can handle it in a variety of environments, resist the "creep"; secondly, his tensile strength and elongation are higher than the aluminum conductor a lot; in addition, the thermal expansion coefficient of aaac conductor, connectivity, weight-bearing capacity, corrosion prevention aspect, flexibility, armored characteristic, pressed characteristics also has more obvious advantages over other materials cable.
According to the relevant cable company noted more attractive AAAC conductor in addition to the performance, their cost advantage is its ability to successfully seize important market reasons. The study demonstrated that AAAC conductor service life improved significantly. The main factors affecting the life of the cable insulator are corrosion and high temperatures causing aging.
The AAAC conductor is due to the addition of rare earth elements, with strong corrosion resistance. After the corrosion resistance of aluminum alloy cables for analyzed, the results showed that underwater, in high temperatures, and in another harsh environments, the earth's aluminum alloy corrosion rate is minimal, almost zero. Due to increased service life, costs will be reduced, which is one reason why more and more aluminum cable industry pro-Lai.
