T/CAPEC 21-2020 Electricity industry transmission line power fittings manufacturing supervision technical requirements
Basic Information
Scope
Scope: This document specifies the basic technical requirements for equipment supervision services related to the manufacturing process and quality of power fittings used in 500kV and above transmission line projects. This document applies to the manufacturing supervision of power fittings used in 500kV and above transmission line projects. The manufacturing supervision of power fittings used in transmission line projects of other voltage levels can be implemented with reference to this document. Main technical content: (1) Standard preparation principles: Refer to GB/T 19001 "Quality Management System - Requirements" (idt ISO 9001) and GB/T 19016 "Quality Management System - Project Quality Management Guide" (idt ISO 10006), as well as GB/T 26429-2010 "Specification for Equipment Engineering Supervision". The process approach is adopted, considering the characteristics of service products, and the requirements of relevant product standards for power fittings are taken into account to formulate this standard according to the characteristics of the power fittings supervision industry. This standard mainly regulates the behavior of equipment supervision units in the implementation phase of power fittings manufacturing supervision services, that is, the requirements for equipment supervision services after accepting the entrustment and signing the entrustment contract. This standard divides the power fittings manufacturing supervision services into several links: raw material entry, processing procedures, factory acceptance, and supervision information. It includes terms and definitions related to manufacturing quality, basic requirements for equipment supervision services, supervision during the manufacturing phase, requirements for supervision materials, and basic requirements and witnessing points and control methods for the specific manufacturing process. (2) Scope and reference basis of standard preparation: On the basis of the requirements of GB/T 26429 "Spec
