国外带电作业的发展情况
Development of live working abroad
目前，世界上已经有80多个***开展了带电作业的研究与应用，其中美国、中国、前苏联、日本、加拿大、法国、英国、德国、瑞士、比利时、意大利以及澳大利亚等40多个***已广泛应用带电作业技术。
At present, more than 80 countries in the world h***e carried out the research and application of live working, including the United States, China, the former Soviet Union, Japan, Canada, France, the United Kingdom, Germany, Switzerland, Belgium, Italy and Australia, more than 40 countries h***e widely used live working technology.
带电作业技术的发展，是从配电线路上开始的，然后到输电线路，再向变电站延伸，再到超高压输电线路和特高压输电线路，并且由交流到直流，逐渐成熟。YCB扁电缆 国外带电作业的发展情况

美国的带电作业
Live working in the United States
美国式***早开展带电作业的***。1923年，美国开始在34KV配电线路上探索进行带电作业。美国人当时使用的是木质操作棒，采用地电位方法进行作业。干燥的木质棒，由于其绝缘性能良好，完全能够耐受相对地电压，尽管当时制造的工具显得粗糙且笨重，但毕竟开创了带电作业的先河。YCB扁电缆 国外带电作业的发展情况
The United States is the first country in the world to carry out live working. In 1923, the United States began to explore live working on 34kv distribution lines. At that time, the Americans used wooden operating rods and ground potential method. The dry wooden rod, due to its good insulation performance, can fully withstand the relative ground voltage. Although the tools made at that time were rough and cumbersome, it was the first time for live working after all.
