T/CAPEC 16-2020 Electric power industry DC wall penetration insulation tube manufacturing supervision technical requirements

Scope

Scope: This document specifies the basic technical requirements for equipment supervision services related to the manufacturing process and quality of DC wall-penetrating bushings. This document is applicable to the supervision of the manufacturing of DC wall-penetrating bushings using gas insulation, paper-wrapped insulation, and resin insulation materials in ultra-high voltage DC projects. Conventional DC projects can refer to this document for implementation. Main technical content: (1) This standard specifies the basic technical requirements for equipment supervision services related to the manufacturing process of DC wall-penetrating bushings for DC projects, and is applicable to the equipment manufacturing supervision activities carried out by equipment supervision units for DC wall-penetrating bushings, including basic requirements for supervision services, pre-production inspections, technical document inspections, sampling inspections of raw materials and components, quality supervision during the manufacturing process, witnessing of tests, inspection of packaging and shipment, progress control, and supervision information management. (2) To standardize and unify important terms and definitions related to the supervision of DC wall-penetrating bushings and other related equipment, this document proposes relevant terms and definitions for the supervision of DC wall-penetrating bushings. (3) The supervision implementation process related to manufacturing quality is clearly defined. Appendix "A" is the main witnessing point project list for the supervision of DC wall-penetrating bushings, and Appendix "B" is a reference template for various forms used by supervision units during the supervision process.
