国外主要用的是铝合金电缆

在供配电系统中电力电缆是输送电力的主要设备材料,国内目前常用的是铜芯电缆。而国外主要用的是铝合金电缆。国外在铝质导体的研究和应用方面, 早在40 年前就率先开发出了AA8000 系列电工级铝合金作为导体材料。目前美国90%以上的市政民用及工商建筑都采用的铝合金电缆。成功应用铝合金电缆已40多年。
In the power supply and distribution system, power cable is the main equipment and material for power transmission. At present, copper core cable is commonly used in China. The main cable used abroad is aluminum alloy cable. In the research and application of aluminum conductor abroad, aa8000 series electrical grade aluminum alloy was developed as conductor material as early as 40 years ago. At present, more than 90% of civil and industrial buildings in the United States use aluminum alloy cables. Aluminum alloy cable has been successfully used for more than 40 years.
我国铝合金电缆发展相对较慢,近10年来美国、加拿大等电缆制造商把合金电缆及其附件安装配套系统引进国内,使合金电缆得到了快速发展。同时国家及相关行业也推出相关规范:GBT 31840.1-2015 《额定电压1kV Um1.2kV 到35kV Um40.5kV铝合金芯挤包绝缘电力电缆》、GB/T30552《电缆导体用铝合金线和NB/T42051《额定电压0.6/1kV铝合金导体交联聚乙烯绝缘电缆》。
The development of aluminum alloy cable in China is relatively slow. In recent 10 years, cable manufacturers in the United States, Canada and other cable manufacturers have introduced the alloy cable and its accessory installation system into China, which has made the alloy cable develop rapidly. At the same time, the state and relevant industries have also introduced relevant specifications: GBT 31840.1-2015 aluminum alloy core extruded insulated power cable with rated voltage of 1KV um1.2kv to 35kV um40.5kv, GB / t30552 aluminum alloy wire for cable conductor and Nb / t42051 cross linked polyethylene insulated cable with rated voltage of 0.6/1kv aluminum alloy conductor.
