T/CAPEC 32-2023 Active

Scope: This document specifies the technical requirements for the supervision of the manufacture of enclosed busbars (including phase-separated enclosed busbars of 1kV and above, shared-box enclosed busbars, and fully insulated cast busbars). This document applies to the supervision of the manufacture of phase-separated enclosed busbars, shared-box enclosed busbars, and fully insulated cast busbars of 1kV and above. The supervision of the manufacture of other special busbars, such as insulated pipe busbars, can be referenced for implementation. This document does not apply to the supervision of the manufacture of gas-insulated metal-enclosed transmission lines (GIL) and cable-type transmission lines. Main technical content: (1) Clarifies the scope of the technical requirements for the supervision of the manufacture of enclosed busbars, which applies to phase-separated enclosed busbars and shared-box enclosed busbars of 1kV and above (including fully insulated cast busbars). The supervision of the manufacture of other special busbars, such as insulated pipe busbars, can be referenced for implementation. However, this standard does not apply to GIL and cable-type transmission line equipment. (2) Summarizes the relevant standard documents referenced in the preparation of the "Technical Requirements for the Supervision of the Manufacture of Enclosed Busbars". (3) Clarifies the supervision implementation process related to manufacturing quality. Appendix "A" includes a list of the main witness points for enclosed busbars, with a column for supervision key points.
