In 1960, Liaoji Electric Power Bureau designated the safety work rules for the maintenance of high voltage overhead lines without power failure, which is called the first guiding live line work rules in China. It indicates that the live working in our country has stepped into normal. During this period, the nationwide non-stop maintenance work changed from simple technology promotion to the stage of innovation and development combined with the specific conditions and production tasks of the region. Besides indirect operation and direct equipotential operation, the maintenance method also moved towards the direction of water washing and explosion crimping lamp. The maintenance tools have changed from the original heavy tools such as support, pull and suspender to the light and rope tools. The insulated rope ladder and insulated pulley block with oriental characteristics have also been widely used. The operation project is marching towards the complex project of replacing conductor, overhead ground wire, mobile tower and transforming tower head lamp.
In November 1964, live line maintenance performance was held in Tianjin, which had a positive impact on the promotion of these new technologies nationwide.
In 1966, the production department of the former Ministry of water resources and electricity held a national live working live watching performance conference in Anshan, marking the development of live working in China to the stage of popularization, and also promoting the development of live working to a newer and deeper field.
