Scope: This document specifies the basic technical requirements for equipment supervision services related to the manufacturing process and quality of optical fiber composite overhead ground wires (OPGW) used in transmission line projects with voltages of 500kV and above. This document applies to the supervision of the manufacturing of optical fiber composite overhead ground wires (OPGW) for transmission line projects with voltages of 500kV and above. Other voltage levels of optical fiber composite overhead ground wires (OPGW) can be referenced for implementation. Main technical content: (1) Standard preparation principles: Referencing GB/T 19001 *Quality Management Systems – Requirements* (idt ISO 9001) and GB/T 19016 *Quality Management Systems – Guidelines for Project Quality Management*, as well as GB/T 26429-2010 *Specification for Equipment Engineering Supervision*, the standard adopts a process-based approach, considers the characteristics of service products, and is formulated based on the requirements of relevant product standards for optical fiber composite overhead ground wires (OPGW) and the characteristics of the OPGW supervision industry. This standard primarily regulates the behavior of equipment supervision units during the implementation phase of OPGW manufacturing supervision services, that is, the requirements for equipment supervision services after accepting the commission and signing the contract. (2) Scope and reference basis of the standard: On the basis of the requirements of GB/T 26429 *Specification for Equipment Engineering Supervision*, the standard specifies terms and definitions related to manufacturing quality, basic requirements for equipment supervision services, key points of witnessing and control methods for the manufacturing process, and requirements for supervision materials. The standard is drafted in combination with the relevant contents of current standards such as GB/T 1179 *Round Conductor with Centric Stranding*, GB/
