Description
技术领域technical field

目前，国内外低压电力用电线电缆要求多种多样，要求也更苛刻，既要求电缆安全地传输电能，有要求电缆尽量节约材料，特别是“铜”等贵金属材料。在这种矛盾的情况下，现有技术的低压电力电缆已不完全适应时代的发展。目前国内外还没有这方面技术报道，就是既能满足电力传输的要求，又能节约贵金属铜的用量以及具有防火等特殊要求的低压电力电缆的技术。世界已探明的铜储量仅约9.4亿吨，其中可供开采的仅为4.7亿吨，所以铜的资源有限，而地球上含量最多的金属-铝Al，占整个地壳重量为8％。At present, there are many kinds of low-voltage power wires and cables at home and abroad, and the requirements are more stringent. Not only the cables are required to transmit electric energy safely, but also the cables are required to save materials as much as possible, especially precious metal materials such as "copper". In this contradictory situation, the low-voltage power cables of the prior art are not fully adapted to the development of the times. At present, there is no technical report in this area at home and abroad, which is a technology that can not only meet the requirements of power transmission, but also save the amount of precious metal copper and low-voltage power cables with special requirements such as fire prevention. The world's proven copper reserves are only about 940 million tons, of which only 470 million tons can be mined, so copper resources are limited, and the most abundant metal on the earth - aluminum Al, accounts for 8% of the entire crustal weight.
