GB/T 18857-2019 Active

This standard specifies the general requirements, work system, operating methods, technical requirements, testing and transportation of tools and equipment, precautions for work, and typical work items for live working on distribution lines with voltages of 10 kV to 35 kV.
This standard applies to live maintenance and repair work on distribution lines with voltages of 10 kV in areas with altitudes of 4,500 m or lower, and distribution lines with voltages of 20 kV to 35 kV in areas with altitudes of 1,000 m or lower. Live working on 3 kV and 6 kV lines can refer to this standard.
Note: Given the variety of electrical equipment types, significant differences in the layout of equipment on poles, and a wide range of work items, this standard only provides guiding principles for work items and operating methods.
