Description

High and low temperature resistant aluminum alloy power cables

technical field

The utility model relates to a power cable, in particular to a high and low temperature resistant aluminum alloy power cable. the

Background technique

With the international copper price rising all the way, many manufacturers in my country's wire and cable industry have been miserable. A few days ago, a senior expert in my country's nonferrous metal industry said that replacing copper with aluminum for wires and cables is a development trend, but there is still a long way to go to achieve the desired application effect. The voice of experts not only pointed out the problems existing in the wire and cable industry, but also affirmed that the replacement of copper with aluminum is an inevitable choice for the development of the industry. my country is a country with a shortage of copper resources, and the output rate of refined copper is only 40%. It accounts for 25% of the consumption of copper resources, while aluminum reserves are abundant and the price is low. Using aluminum as a substitute product has become a way out for many industries. In the 1970s, aluminum replaced copper for the first time in the automotive radiator (water tank) market, and now it has basically realized the replacement of all cars; in 2006, Alcoa Chairman Belda made it clear in the company's second quarter earnings conference call The heat exchanger products are completely made of aluminum, so they have built new factories in the United States and Europe. In the home appliance industry, in 2007, 12 large air-conditioning companies consumed 10 million sets of copper-aluminum connecting pipes for air conditioners, replacing 11,000 tons of copper; and according to the international KFB survey report, companies including Carrier, LG, and Japan In 2007, the utilization rate of copper-aluminum connecting pipes for air conditioners in the world was 55%. the

Through scientific research, the "high and low temperature aluminum alloy power cable" has been developed, which has great value in popularization and application, and can achieve the purpose of "replacing copper with aluminum", greatly saving the scarce copper resources in our country and creating a huge economic society. benefit. Different from the traditional copper core cable, this aluminum alloy cable is made of high-elongation aluminum alloy material. By adding iron and other materials into pure aluminum, and undergoing compression stranding process and special annealing treatment, the gaps in the alloy aluminum "Extrusion" cleanly reduces the cross-sectional area and has good flexibility; the insulating material is made of silicone rubber or fluoroplastic, and the steel wire braided armor structure is used. the

According to experts, the safety performance of the high and low temperature aluminum alloy cable is better than that of the copper core cable. When its surface is in contact with the air, it will form a thin and strong oxide layer, which can withstand various corrosions. Because of the high creep properties due to the addition of iron, the connection is guaranteed to be stable even under prolonged overload and overheating. the

In addition, the rebound performance of this aluminum cable is 40% smaller than that of copper cables, and its flexibility is 24% higher than that of copper cables. Because the weight of high and low temperature resistant aluminum alloy cables is only 50% of that of copper cables, it can also effectively reduce installation costs. the

It is reported that aluminum alloy cables are widely used in many famous engineering projects in the world due to their advanced and mature technology, such as Atlanta Olympic venues, Washington Convention and Exhibition Center, New York Airport, etc. The use shows that the aluminum alloy cables produced and installed according to the specifications have never had any failures in use. the
