一、概述电缆的冷压连接是一项较为先进的工艺。在过去,电缆连接基本上都是采用锡焊焊接。这虽然满足运行要求,但焊接工艺存在着操作技术要求高,劳动条件差,不安全及接头允许短路温升较低等缺点。而冷压连接工艺具有工艺简单,性能稳定可靠,生产率高,劳动条件好,允许短路温升较高,节省有色金属等优点,特别对战时抢修电缆和实现船舶总段建造工艺具有重要意义。因此,近年来,许多国家都对电缆冷压连接工艺进行了研究,并越来越广泛地应用到生产中去。我国的造船工业,在十几年前就开始采用电缆冷压连接工艺,上海沪东造船厂1964年在120毫米~2以下的电缆上采用了这种工艺,取得 First, an overview of the cable cold connection is a more advanced technology. In the past, cable connections were basically soldered. Although this meets the operational requirements, there are some shortcomings in the welding technology, such as high technical requirements for operation, poor working conditions, unsafe conditions, and low allowable short-circuit temperature rise of joints. However, the cold-pressed connection process has the advantages of simple process, stable and reliable performance, high productivity, good working conditions, high short-circuit temperature rise, and non-ferrous metal saving, especially for repairing cables during wartime and realizing the construction process of the ship segment. Therefore, in recent years, many countries have studied the cable cold connection process, and more and more widely applied to the production. China’s shipbuilding industry, more than a decade ago began to use cable cold connection process, Shanghai Hudong Shipyard in 1964 120 mm ~ 2 in the following cable using this technology to obtain
