Low cost aluminum alloy cable

Single joints of aluminum core wire and multi-stranded copper core wire with relatively large cross-sectional dimension of copper coarse wire should use hexagonal hydraulic connection pad method for joints with large difference in cross-sectional dimension of copper coarse wire. Should not use clamp crimping method. For example: 16mm and 30mm copper wire connection. For this purpose, it is also possible to hydraulically connect branched connectors. Newly built overhead insulated distribution lines with a rated voltage of 1 kV and below cannot be wound, but should be connected using clips and connection pipes. When the line is a LGJ-400/65 or less wire, a 100t class hydraulic press is used for the crimping work. For a LGJ-500/45 or less wire, a 200t class hydraulic press is preferred for crimping. The upper and lower molds should be aligned during the hydraulic connection. The tube should be flat and the nozzle and seal should be coincident. After the pipe has been pressed, it should be scraped and polished. There should be no obvious distortion and bending of the pipe after it is pressed, otherwise it should be straightened. For overhead lines that cannot be clamped by crimping or hydraulic connections, the explosion pressure method may be used, but the lines must be highly clean.

To achieve the same electrical performance, the direct purchase cost of aluminum alloy cable is 20% lower than that of copper cable, and the construction and installation cost of 1KV power cable can save more than 20%. As copper resources gradually deplete and cable demand continues to increase, aluminum alloy cables can not only save a lot of investment, but also have an inestimable effect on creating a conservation-oriented society.

There is a basic relationship between the channel bandwidth measured in MHz and the information transmission capability or data transmission rate measured in Mb/s. The traffic flow on the freeway mainline can be used to visualize the relationship between bandwidth and data transmission rate concepts. The bandwidth can be compared to the number of lanes on the highway and the data transmission rate can be compared to traffic flow or the number of vehicles per hour. One way to increase traffic flow is to widen the highway. The failure of high-voltage power cables is mostly caused by fire and the other is to improve the road quality and remove bottlenecks. Similarly, it is also possible to carry more information bit amounts per Hz frequency within the available bandwidth frequency, but this requires a better signal-to-noise ratio.

In the course of circuit design, the capacity of the site should be accurately verified, and the possibility of adding capacity in the future should be fully considered, and the appropriate type of wire should be selected. Large capacity, should choose thicker wire. Line design and reasonable selection are the key steps in preventing overload. If the type of design is not properly selected, it will leave behind congenital risks that are difficult to rectify. Certain small projects and sites are not carefully designed and selected. It is very dangerous to choose and lay the line at will. Newly added electrical appliances and electrical equipment should fully consider the bearing capacity of existing lines. If the original line does not meet the requirements, it should be redesigned and reformed.

In 2012, Changfeng Cable introduced the American 8000 series aluminum alloy cable conductor production technology and aluminum alloy cable manufacturing technology through the United States Jiayilun Cable Co., Ltd., and invested a large number of technical personnel and capital equipment, after long-term independent research and development and trial and error , Now available to the Chinese market with 35kV and below armored aluminum alloy cable, non-armored aluminum alloy cable, sheathed aluminum alloy cable, pre-branched aluminum alloy cable and various types of copper cable. Jiayilun Marketing Center has an industry-leading marketing elite team, a number of highly sophisticated talents, with standardized market management and professional marketing capabilities, with unique industry forward-looking and accurate market analysis capabilities. Jia Yilun also has direct service agencies and spot warehouses in Beijing, Tianjin, Shanghai, Chongqing, and Heilongjiang to ensure the speedy response and rapid and timely logistics and distribution capabilities of Katherine. At present, China's cable industry is relatively weak, so it is necessary to have a number of backbones and always concentrate on the development of the cable industry. To enhance competitiveness with innovation and reputation with quality, it is hoped to support the banner of the cable industry. Jiayilun aluminum alloy cable will become a dazzling star in the cable industry.
