Model-specific type test
KYN28A-12
Type-test report matched to the stated 12 kV model and reference rating.
Quality that can be audited
Quality & delivery assurance
Evidence, manufacturing controls and witnessed release are treated as one continuous chain.
Standards and verification framework
Requirements are mapped to the offered product
Standards listed here are project compliance references, not blanket certification claims. Existing reports may be based on corresponding GB/T standards; applicability is verified during qualification.

Manufacturing quality control
Fabrication and assembly share one quality chain
Approved drawings, BOM and material specifications lead into cutting, punching, bending, welding, structural inspection, busbar work, device installation, wiring and routine verification.
Project-specific witness points and test scope follow the approved ITP and contract documents.
International delivery readiness
Documents and release practices prepared for export projects
These capabilities describe document preparation and factory release practices. The current website does not claim an overseas project reference.
Controlled submittalsAvailable by project
Drawings, data sheets, component schedules and document registers can be prepared for review against the agreed project scope. Final format and submission schedule follow the contract document requirements.
Inspection planningAvailable by project
An inspection and test plan can identify hold points, routine checks, applicable evidence and required release records. Witness points and third-party involvement are confirmed for each project.
FAT and release recordsAvailable by project
Factory acceptance testing can follow an approved procedure with results, observations and punch-list status included in the project dossier. The final FAT scope follows approved specifications and procedures.
Export handoverAvailable by project
Final documentation, packing marks, shipping data and the agreed handover package can be checked before release for export. Packing and documentation requirements are confirmed before manufacturing release.
