This standard is revised according to the national standard formulation and revision plan of the National Quality and Technical Supervision Commission. GB/T2900.51—1998 "Electrical Terminology Overhead Lines" was referenced when revising the original standard. There are many items in the original standard, and this standard has been merged. A total of 75 items are listed in this standard, of which 25 are newly added. Appendix A and Appendix B of this standard are both prompt appendices. This standard was proposed by the former Ministry of Electric Power Industry.
This standard is under the jurisdiction of the National Technical Committee for Standardization of Overhead Lines (Electric Power Fittings). This standard was drafted by the Electric Power Construction Research Institute of the State Power Corporation. The main drafters of this standard are: Bo Tong, Xu Naiguan, Dong Ji, You Chuanyong. This standard is interpreted by the National Technical Committee for Standardization of Overhead Lines (Electric Power Fittings). 1 Scope
