Description :

　　Aluminum clad steel core aluminum stranded wire is an overhead conductor composed of aluminum clad steel wire as a reinforcing core and hard aluminum wire twisted together. Compared with ordinary steel cored aluminum stranded wire, aluminum clad steel cored aluminum stranded wire is 5% lighter in weight, 2-3% higher in current carrying capacity, 1-2% less sag, 4-6% less power loss, and has good anti-corrosion performance, long service life, simple structure, easy installation and maintenance, and large transmission capacity. It is widely applicable to transmission lines of various voltage levels and transmission lines that require an increased aluminum steel section ratio. It can also be used for transmission lines in coastal areas, saline alkali beaches, and third - and fourth level industrial pollution areas.

　　Aluminum clad steel wire and its characteristics

　　Aluminum clad steel wire is a bimetallic wire that is uniformly, continuously, and tightly wrapped around a round steel wire with a layer of aluminum. Aluminum has relatively low strength but is relatively light, with a density of about one-third that of copper. Its electrical conductivity is relatively high, ranking third after silver and copper. Aluminum has better corrosion resistance: steel has higher strength, but lower electrical conductivity and corrosion resistance. Therefore, aluminum clad steel wire is the product of the strong combination and strong weak complementarity of aluminum and steel. It has the following characteristics:

　　(1) The adjustable range of size and performance for aluminum clad steel wire is relatively large.

　　(2) The bonding between steel and aluminum belongs to metallurgical bonding, so the bonding strength is good, which is conducive to the strength advantage of aluminum clad steel wire.

　　(3) Compared with galvanized steel wire, it has better heat resistance because the melting point of aluminum is higher than that of zinc, and the melting point of steel is even higher.

　　(4) Baosteel wire has good corrosion resistance. If aluminum clad steel wire is twisted together with aluminum wire or aluminum alloy wire and applied on overhead transmission lines, there is no problem of electrochemical corrosion. But galvanized steel wire has this problem. Thus, anti-corrosion isolation protection is used.

　　(5) The cross-section of a wire can be made into complex shapes. For example, aluminum clad steel contact wires (tram wires) used in electrified railways. Its shape is an "8" shape, and one of its manufacturing methods is to use the Conform continuous extrusion method to form it in one go.

　　(6) Aluminum plated steel wire, like galvanized steel wire, is manufactured using the pre immersion method and is a reinforcing material, not a conductive material. Aluminum coated steel wire has lower strength than zinc coated steel wire due to the higher temperature of hot-dip coating compared to galvanized steel wire. In addition, the plating process requires high standards, which can easily cause discontinuous "pinhole" defects. This actually accelerates corrosion. After the 1960s, relevant units in China carried out some work on the development of aluminum plated steel wire. But in fact, industrial production has not been achieved, so it has not been widely promoted and applied in China. In addition, aluminum coated steel wire faced strong competition from aluminum coated steel wire during the same period. Aluminum coated steel wire has obvious performance advantages, and it is expected that aluminum coated steel wire will not have any improvement in its application in transmission lines in the future.

　　powder metallurgy

　　Powder metallurgy is a process technology for producing metal powders or using metal powders (or mixtures of metal powders and non-metal powders) as raw materials, forming and sintering them to manufacture metal materials, composite materials, and various types of products. The powder metallurgy method has similarities with the production of ceramics, both of which belong to powder sintering technology. Therefore, a series of new powder metallurgy technologies can also be used for the preparation of ceramic materials. Due to the advantages of powder metallurgy technology, it has become the key to solving new material problems and plays a crucial role in the development of new materials.

　　Powder metallurgy includes powder production and finished products. Among them, powder production is mainly a metallurgical process, which is consistent with the literal meaning. Powder metallurgy products often go far beyond the scope of materials and metallurgy, and are often interdisciplinary technologies (materials and metallurgy, machinery and mechanics, etc.). Especially modern metal powder 3D printing, integrating mechanical engineering CAD、 The integration of reverse engineering technology, layered manufacturing technology, numerical control technology, materials science, and laser technology has made powder metallurgy product technology a modern comprehensive technology that spans more disciplines.
