江苏春晨电缆有限公司生产春晨YCB扁电缆3*4+2*3卷筒扁电缆，

1956年，进一步发展到带电更换44~66KV的木质直线杆、横担和绝缘子。

In 1956, it was further developed to replace 44-66kv wooden straight pole, cross arm and insulator with electricity.

1957年10月，东北电业局设计类套220KV高压输电线路带电作业工具，春晨YCB扁电缆3*4+2*3卷筒扁电缆并成功应用于220KV高压输电线路的带电作业。同时3.3~33KV木杆和铁塔线路的全套检修工具，也得到了改进和完善，这就为各级电压线路推进不停电检修尊定了物质和技术基础。

In October 1957, Northeast Electric Power Bureau designed the first set of live working tools for 220kV high-voltage transmission line, which was successfully applied to live working of 220kV high-voltage transmission line. At the same time, the complete set of maintenance tools for 3.3 ~ 33kV wooden poles and tower lines have also been improved and improved, which lays a material and technical foundation for promoting the maintenance of all levels of voltage lines without power failure.

1958年，当时的沈阳中心实验所开始了人体直接接触导线检修的实验研究。在学习国外经验的基础上，解决了高压电场的屏蔽问题，并在试验场成功地进行了我国次人体直接接触220KV带电导线的等电位实验，次在220KV线路上完成了等电位作业和修补导线的任务。这次等电位带电作业的实验成功，了中国带电作业的新篇章。从此等电位作业技术在中国带电作业中得到了广泛应用。

In 1958, the Shenyang Central Experimental Institute began the experimental research on the maintenance of human direct contact wire. On the basis of learning foreign experience, the shielding problem of high-voltage electric field is solved, and the first equipotential experiment of human body directly contacting with 220kV live wire in our country is successfully carried out in the test field, and the task of equipotential operation and wire repair on 220kV line is completed for the first time. The success of this equipotential live working experiment has opened a new chapter of live working in China. Since then, equipotential operation technology has been widely used in live working in China.

1959年前后，鞍山局又在3.3~220KV户外输配电装置上，研究出了一套不停电检修变电设备的工具和作业方法至此，中国带电作业技术已发展成为3.3~220KV包括输电、变电、配电三方面的综合性检修技术。

Before and after 1959, Anshan Bureau developed a set of tools and operation methods for non-stop maintenance of substation equipment on 3.3-220kv outdoor transmission and distribution equipment. So far, China's live working technology has developed into a comprehensive maintenance technology of 3.3-220kv, including transmission, transformation and distribution.
